It’s a silly system, where everyone has to invest their time (optimizing for rewards, avoiding interest) in an ultimately negative sum game. I hate it so much.
The intuition being: people who carry balances and pay interest don't actually spend very much; they are not wealthy.
That's the interchange income corresponding to wealthy people. Interchange is paid by the card-accepting business, not by the buyer. The buyer pays interest and other fees and that graph looks very different.
From that original study the full picture table says in % of ADB that the "poorest" (below 620 FICO) pay ~45% interest and fees but bring only 2% additionally in interchange income. The wealthy (at 800+) pay ~10% interest and fees but bring another almost 10% interchange income, on 4 times higher spending, and 3 times higher rewards (so the wealthy get ~12 times higher rewards in $ value than the "poor").
Just the percentages paid by each group more than offset the difference in spending. There are also way more "poor" accounts than wealthy accounts. Intuitively you can tell that the banks are effectively subsidizing the fees and interest for the wealthy with the income from the poor, for the sake of the interchange income which is mostly generated by the wealthy but doesn't come from their pocket.
Those poorest of people (<620 FICO) pay more interest and fees (percentage and absolute terms) than any other group. There's a range in the middle on the wealth scale where the customers are actually a net loss for the banks (the 660-760 FICO range).
The most recent I've seen otherwise is this Federal Reserve study[0] from 2022. It finds that the marginal return on swipes is actually slightly negative because of how juicy rewards have gotten, and 80% of their profitability comes from interest (with most of the rest fees):
> we find that, on average, the credit function makes up approximately 80 percent of the credit card profitability, whereas the contribution of the transaction function is slightly negative, as rewards and other expenses on credit card transactions outpace banks' interchange revenues.5 In addition, fees—in particular late fees—comprise approximately 15 percent of credit card profitability.

Capital One also is supposedly huge on car loans; I'd imagine the interest from those would comprise a big chunk of that revenue.

Now I just use my apple card everywhere, pay it off every month and get whatever rewards I get.
It feels like a weird situation, those that stand to gain the most from credit cards are also the ones that should feel a difference of under $100 in rewards the least.
The one exception I see is bonus sign up rewards since those can be fairly significant, or making sure you use an airline card at the airline since those bonuses can be fairly significant (with sometimes other benefits). But outside of those exceptions, just choose a card with good rewards and stick with that and pay it off every month.
So like, I have a card that's 6% on groceries, another that's 3% on gas and restaurants, Apple Card does 2% on Apple Pay transactions, and I have a 1.5% card for everything else.
On the one hand, relative to our income it's not so important, but on the other it feels bad leaving $3k on the table.
You can just opt out of using credit cards.
You can still implement “if I can’t afford something, I don’t buy it” with a cc. I pay mine off every month so it’s financially the same s a debit card but use a premium card for its purchase benefits.
I always get my money back when this happens with a credit card purchase. I've also had to dispute things occasionally, and I almost always get refunded.
Opting out doesn't save you from those costs.
I never understood why whole nation wants to live in debt just to have one extra month of cash flow (which they’ll probably squander soon).
https://en.wikipedia.org/wiki/List_of_countries_by_household...
Rational if you want a mortgage in the US at least.
Currently you're keeping money in the bank accruing the bank interest to occasionally pay for stuff.
With a credit card you would get various bonuses/cashback/gameified returns by owing them money, and it costs you nothing as long as you pay them back once a month interest free.
If you however slip up/miss a payment it will cost you a lot.
Both cases suck, but the latter saves you money if you play that game.
That's from a EU perspective. From a US perspective you also require it from a credit score perspective, which EU thankfully hasn't adopted... yet.
The entire credit card industry is set up to squeeze out as much profit from people as possible. They offer discounts as an incentive, but it is a huge trap that many, many people fall into. I'm not interested in risk. I'm interested in simplicity.
It's participating in the credit card industry that is foolish.
I see many commercials for local banking up here that pulls out 30-40+ year members of the banks boasting about the prosperity the bank provided them, but at the same time, when they'd walked into the bank back in the day A Guy just said "yeah he's good for it" and wrote out the loans they needed.
You can't opt out of the modern credit scoring system and if you fuck it up even once with a bad line item you're out of the running for quite a few things and become virtually poor.
That’s why businesses eat the credit card fees.
For the consumer the reason is that this is revolving credit. If you pay next month you can have stuff today. That's a small relief, unless it turns into a carried balance and then it's an ongoing burden, but you don't think about that burden at first because you're naturally optimistic.
It is risky and it is very easy to lose great amounts of money on a bad decision when credit is involved. Arguably that makes it bad. But still not negative sum.
I love it. As someone who never carries a balance I get paid by banks for doing pretty much nothing at all.
And I don't worry about US retailers, I don't live there.
I should add that rewards are not the best benefits. Sign up bonuses are much more lucrative, running to hundreds of dollars per card, and can often be repeated. Same applies to bank accounts.
And it may not work the way you expect. Retailers may favor credit card users if they tend to spend more. There are substantial costs associated with handling cash, so cash users may end up paying more.
But of course banks make huge amounts of money from poor customers via various fees and interest payments. It warms my heart that I get some of those ill gotten gains insead of the evil banks.
Borrowers can also keep from overextending their credit and go on debit cards instead…
Obviously these things can have an impact on people but before the 80s credit cards were not widely available to people with high credit risk and the world still functioned.
Of course there’s going to be a a cost to spending beyond your means.
I don’t have any data, but my intuition is that overall high-fee, high-reward cards increase propensity for consumer spending by at least a few % beyond the fees/rewards.
The merchants think so, too, or they wouldn’t accept the processors that let their banks hand out these cards.
Visa / Mastercard / American Express all have lines of premium credit cards (Visa Infinite, World Elite Mastercard, Amex Platinum), and they're very much too big to ban. You'd just be left with one processor in the US (Discover, now owned by Capital One).
If they’re truly too big to give up no matter the fees they charge, they’re leaving money on the table.
Of course, they can’t. If Chase started handing college students a 3% card, the merchants would riot.
In recent years, all of my utilities have added 3%+ credit card surcharges, so I pay most of my household expenses with debit cards/ACH now.
Tmobile, Comcast, Verizon, ATT, Target, grocery store, electric utility and water utility (government), annual vehicle tax (government), auto body shop, daycare, and any home repair contractors all charge 3%+ (or give a discount, same thing), so I basically only use credit cards for other retail stores and travel and restaurants.
One of the most corrupting yet hidden forces in America today are the payment networks MC/Visa etc. due to their bribing and corruption of the government in order to prevent things like making payment processor fees separate/independent of the cost, i.e., similar to how taxes are added after the fact, not included in the price; and also preventing merchants from having two different prices, cash vs card.
I’m a bit surprised that HBR does not seem to even really have an accurate mental model if the matter, unless they’re making an editorial choice to speak in vernacular turns to relate it to the audience.
The problem is not really the cards, it even credit cards, it’s actually the payment processing networks that are the corrupting force.
If America has a legitimate government, there would have been a federal alternative payment processor that charges nothing as an accompaniment and based on the authority to mint the currency, which is what a payment processor today is, a digital currency mint.
To put it into perspective, when you purchase something by credit card, a merchant may have to l pay a little under 3% on a $100 purchase. When you purchase something cheaper let’s say $5, a merchant may pay 6.5%. And no, they don’t just say “awe shucks, I guess I’ll lose that money”, They increase the prices by some averaged amount.
Some may say that they can’t do that because competition, well, because there is no real competition and because the payment processor de facto monopoly/cartel has basically every single company in lockdown and you have no real alternatives, especially in places like Europe where they’ve foolishly and enthusiastically started forcing everyone into digital payment, all the merchants simply roll what is effectively a kind of organized crime/mob extortion into the prices of the goods and services the common person pays and never knows is paying.
That is not a positive. I'm fine with splitting up a price if you want to show how much tax gets added, but having to continuously do the mental math of "no this item is 10.99 it's 10.99 + tax" is very frustrating. When I pick up a $11 item, I want to spend $11.
In Europe (or at least the EEA, but the UK and I think Switzerland have their own capping) card interchange is capped at, generally, 0.3%.
>When merchants raise prices for all consumers in response to these costs, users of low-cost payment methods (e.g., cash and debit) cross-subsidize high-reward credit card users who shop at the same merchant"
Cash handling is not a low-cost payment method, Cash handling can cost businesses between 4% and 15% of each transaction, when factoring in labor, security, bank fees, and risks like theft and counterfeit bills.
One could argue that credit card users have been lowering prices for cash payers as business avoid cash handling pitfalls and get their funds safer and faster.
So in US card processing is x5-x10 more expensive.
At least we have cheap gas? farts
Healthcare, education, and housing are expensive in the US for the same primary reason: political interventions that simultaneously subsidize demand and restrict supply.
e.g. https://documentscontractuels.orange.fr/les-offres-orange-mo...
Canadians like myself have ~40% of our provincial taxes spent on healthcare, so in my case about ~8% of my gross income. Somewhere in the tune of $20k/yr. While I was living in Seattle and filing American, quite a bit less of my gross income went to healthcare. Just food for thought.
Well, maybe I spoke too soon, because my private American healthcare turns out to also be about 8% of my gross income (of $60k)(before copays and my deductible)(and also it's crap). Twinsies!
But yes I agree that it would be awful to have my health needs taken care of and a mere ~160k USD left to spend on everything else.
That does even begin to touch on crazy laws banning people from setting up their own ISP to compete: https://www.techdirt.com/2024/11/07/16-u-s-states-still-ban-....
Debit card fees are capped in the US, yet I’ve never received a discount from a merchant for paying with debit instead of credit.
As such, I just pay with credit and have never understood this argument.
Because the merchant pass the higher processing cost to all customers.
Second thing: interchange fees are not the only fees that your typical store has to pay, the total fees are much higher. I think the EU essentially capped Visa/Mastercard profit in the EU, more than they capped small business fees for card payment.
This feels like a potential arbitrage opportunity... I live in Sweden, but if I can use a US credit card I can get high rewards?
You will probably not see rates that are even competitive with a dodgy FX cash place at an airport, let alone with the numbers you've seen on financial networks for what FX transactions by banks cost, but you feel happy because there was "no fee".
The card companies always add a margin to FX conversions, usually in the 0.5% range. This is fairly benign since the market rate can move between the transaction and the settlement, so sometimes you save money.
You see at the bottom of restaurant menus a note stating this.
It also applies to Danish business credit cards, as those aren't covered by the consumer credit card fee limits.
E.g. for now I have the most premium card offered by my bank (50€/mo), and it gets me extra product insurance, rental car insurance, travel insurance, free lounge access, and some other things like that, but no cashback or similar.
I think some premium cards do offer cashback nowadays, but they are in the minority. Some cards also offer airline reward points. My experience is limited to Finland, though.
Some weird crypto stuff can give more cashback, but it mostly for scheming nerds.
There are some specific discounts and benefits but not cash rewards.
It is illegal (not banks will not let you, actual legislation) here to charge more for card payments or discount for cash or bank transfer.
There is a lot that goes into it, and it is interesting how customers like me who literally never have carried interest and have to made thousands of $ in rewards over the years still make the banks money....
https://www.bitsaboutmoney.com/archive/anatomy-of-credit-car...
They are a way for airlines to create value out of thin air with their own fiat currency. For the average consumer the miles create less of a pure economic efficient benefit and more of a psychic benefit - funny money bucket that accumulates to defray some trip expenses. Economically they'd be best off with an outright 2% back card.
For the minority of customers who are flexible on dates/locations and willing to plan in advance - most airline/hotel programs have sweet spots at the more premium level.
I use them to fly overseas business class refundable fares at discount. It's not free, but the taxes paid + foregone $ I could have gotten with a cash-back card ends up being 2-3x economy non-refundable fare instead of the 5-7x listed cash price if I bought the business class ticket outright.
It's generally a time-vs-money thing though in that to maximize airline/hotel programs you need to pay attention to various limited time offers for signup bonuses, spending bonuses, conversion bonuses, redemption bonuses, etc. Without those it's a very uphill battle.
Credit card hotel booking portals are often much worse than what's available too.
For example, you might end up paying 30-100% more for a hotel booked through Chase Travel. At the very least you'll have way less selection. Even if price matching exists, you could still end up paying more.
I am traveling to Mexico next month and I do have a Chase Sapphire Preferred card (the one with the $95 annual fee). You get $100 in hotel credits per year if you book through Chase Travel.
In one of the spots I'll be at, there was (1) selection. It was $92 for 2 nights in a pretty low populated town that I'll be passing through. That hotel was rated 3.2 stars on Google.
If I use Google search or any hotel aggregator site, there were over 10 hotels available for half the price with much better ratings.
In this case it cost me about $50 extra to use the card's benefits.
Many people don't understand how rewards work when it's marketed towards your annual fee. The $100 credit doesn't offset the $95 annual fee. You pay $95 out of pocket for the fee. As soon as you book that hotel for $100 you've now paid $195 total out of pocket of which $100 gets credited back, so you're still out $95. If you instead didn't have the card and got the hotel at the cheaper rate, you'd only be out $45 or whatever you paid.
I mainly got the card because it had a really good sign up bonus, 0% international exchange fees and reasonable rental car coverage. Other cards can cover these benefits without an annual fee.
What does this mean? I'm not clear what the sweet spot is - are you talking about buying points/miles/etc outright with cash rather than earning them as credit card rewards? Everything I've read is that these are almost always bad deals.
There is no one-size-fits-all answer.
If you do not have time to look into it, plan trips 6-12 months in advance, or have flexibility (will go anywhere thats a deal), then they aren't worth it.
“Saving” airline miles is definitely suboptimal, like you said, getting 2% cash back and redeeming it immediately is the optimal strategy. Money is fungible and cash depreciates.
Plus, the “deals” you have access to with airline miles are not slanted in your favor.

Otherwise, you're giving up 1-3% discount.
Set auto-pay on your credit card to pay in full every month. I've never once paid for credit card interest. I think there's a term inside credit card companies for people like me: leeches or something like that.
that's some odd classism there.
credit card companies love your data. they can package it, sell it, analyze it.
this is real data of actual behavior, not whatever people say or click -- money where the mouth is.
even if they never make a cent off of you from an interest perspective they 1) still get fees from the merchants, and 2) get all of that juicy juicy transaction info -- and that info alone might be worth the costs.
Really helped us float the moving company and also some DIY renovations on our house that we didn't have all the cash on hand to pay for outright. And we didn't pay a thin dime for the privilege.
Another reason is that credit card companies sell your purchase data to aggregators and advertisers, and cash affords more privacy.
At one time, credit card companies forced vendors to charge the same, whether cash or credit, but that seems to have fallen by the wayside.
The problem is, is that cash is becoming less and less acceptable.
In a nearby town, you can't pay for parking, with cash. I have seen credit-card-only vending machines. A lot of restaurants have iPads at the table, and you never see anyone but the bus[boy|girl|whatever], bringing you your food.
I think of it like alcoholics who can't be near alcohol. It's some deep seated degeneracy or fear.
There is no situation in which interchange fees get slashed and prices go down across the board by 3% to make it worth it for card users.
Long term average? Sure, it goes up, that's inflation. But do you know what causes inflationary pressure? Visa and MasterCard adding unjustified fees because they're a duopoly and control most of the payments market, and your government won't regulate them and cap fees.
The UK and the EU both cap debit card fees at 0.2% and credit card fees at 0.3%. When the UK left the EU, Visa and Mastercard jacked up their fees over 5x for UK-EEA payments. Not because they had to, but because they could, and they love sucking money out of other peoples' businesses. https://www.psr.org.uk/our-work/market-reviews/market-review...
Retailers in competitive industries absolutely do use a reduction in card fees to lower their prices. Maybe not all the way, but they definitely don't give it all to themselves as margin; their competitors don't.
Well, there was that time in the 1930s.
I always ask for a discount but for some reason I almost never get it.
The rational move then is to pay in as many installments as I can get without any additional interest. Then time itself gives me the discount. My actual money stays invested and I only pay later. My credit card gives me 1.1% cashback on all purchases. Inflation too does some of the work.
Maybe, but "should" has nothing to do with it. Either I get one or I use my credit card.
> cash costs the merchant MORE than credit card fees
That's not my problem.
I would be curious what percentage of people actually qualifies for a card with over 2% cashback especially without a monthly fee. My guess is that that percentage is very low.
High earner/spender, sure but that's not most people
No affiliation; just a happy user.
If you combine that with a card that gives 2% on everything than it wouldn't be hard to average over 2% cashback as long as you were mindful about using the discover card for qualifying purchases and the 2% card for everything else.
And that's the rub. Credit card companies know most people won't be too mindful most of the time about their spending habits.
Ever since then, I wondered how much of the "not qualifying" is due to misinformation like this.
1. People with proven bad credit.
2. People asking for a lot of money without proven good credit.
3. People asking for more specialized credit, such as lines for businesses or lines for high earners.
Even as someone who is a credit card optimizer, I also ignore numerous 1-3% choices a day.
Many people also spend more than they can cover on it.
People who don't pay their card off also are on the look out for lower interest rate cards and switch all the time. they in reality are not paying the very high rates on cards, they are paying the lower introductory rates (which is still a lot of money). These people are also more likely to default and stop paying leaving the bank to write everything off. Combine that with the fact that they typically don't spend as much over several years (they hit their credit limit and their income won't allow an increase so they have to stop spending), and they are not as profitable as it seems.
(This is not a rhetorical question, I would love to hear others' take on the psychology and history of the subject. Really, how hard is it?)
How exactly to become wealthy then?..
--
> What happened to noblesse oblige?
Some things made noblesse oblige way harder to manifest.
Meritocracy. "I deserve what I have", versus "I got lucky have what I have" made harder to share back.
Globalization. When you use one community to produce and another to consume, and third to register a company, and owner lives in fourth it's hard to associate yourself with the community. Where exactly to give back? You won't even see those people.
Secularizarion. Though USA is still significantly religious place comparing to europe.
Easiness to move. Today you're here, tomorrow you're there in new zealand bunker.
Culture. Somehow the rich are in the people who are heavily interconnected, spend time together at the khe khe pedoisland.
Natural selection. The ones who care less about others mathematically have more advantage than those who care enough to spend resources on non-resource-aggregation activities.
--
So. There is no intristic motivation to do so (with majority), there is no external motivation, and there is no repercussions of not giving back.
Sure, take any slice of a vast number, and you get a big number.
It's not a "wealth transfer" when everyone gets what they bargained for and can opt in or out.
Most importantly, the transaction value of using credit cards or rewards systems - what the user actually gets - is not enumerated.
Beyond what others have noted (mainly deferred payment), credit cards offer legal transaction protections: my legal liability for fraud is limited (unlike debit or Zelle transfers), and I can challenge any transaction even later, which gives the vendor an incentive to ensure I'm happy even after they have my money. While reputation provides some incentive for repeat customers, the ability to retract a transaction governs even non-repeats. I would submit this alone has improves quality of service for everyone anywhere credit cards are accepted.
Rewards vary by type. Cash-back rewards reflect the fact that interchange fees were set to recapture initial investments, but servicing costs have plummeting (thanks to computing); governance-wise, it's almost impossible for a "representative" political system to extract a large cost from a small number of powerful agents with vested interests to provide a tiny amount of benefit to a very large numbers of other people. But that's a much more extensive governance issue.
So where does the benefit go? To competition between credit providers, initially as cash-back, and then to tying rebates to future purchases within controlled channels. For airline point systems that give free flights or upgrades, it improves retention, but other forms of rewards would seem to verge on tying, where power in one market is extended into another.
Politically-mediated wealth transfers are a political issue. Economically-mediated wealth transfers should raise market-regulation policy issues, in particular whether the law is inducing or protecting them, and then whether they are good or bad. Tallying that requires not just seeing the money flow, but seeing all the value received or cost exported.
I also used a credit card to bootstrap my business 15 years ago. At it's height, I was brining in $1 million/year. The bank would have never given me a loan for the amount I was able to use on a credit card. I ended up shutting the business down a few years ago, with no debt.
Most people can't handle spending and rack up tons of debt. Credit cards can also be used to make money, instead of buying stupid things you can't afford.
[1] of course, this doesn't need to rely on some principle that people are entitled to discounts if they buy more, because in reality discounts arise from complex market dynamics such as competition and price discrimination.
https://news.ycombinator.com/item?id=39928604
Same argument for people: managing cash is a pain, swiping a card is easy. Contesting a transaction or fraud is way easier (infinitely easier?) with a card than cash. Having day to day liquidity even without ever carrying a balance is nice.
Is all this worth $9.2B across the economy? Maybe not, but again, certainly worth more than 0.
Nobody's arguing that credit card companies are proving zero value, only that they're charging more than what can be "justified" (whatever that means). That's why in europe the interchange rates are capped at some amount to reflect that.
It's clearly more complex than the story these authors are telling, in particular the highest income consumers get the worst returns on their interchange payments. So stores and services catering to wealthy consumers are actually subsidizing an opportunity for savvy customers, many of whom are not wealthy
I think the most simple piece of legislation to solve a lot of problems is to allow merchants to pass along the interchange rate to their customers. If they could do this legally and operationally, this would solve most issues here. If a credit card wants to be expensive, fine the consumer should pay for it. Because of contractual and operational limitations, credit card companies have gotten themselves into the current arms race.
If stripe implemented this, it would make me appreciate them as a force for good instead of being a part of the problem.
That's not what the article says:
>High-income consumers with high FICO scores benefit the most from reward credit cards compared to mid- and low-income consumers with high FICO scores. At the lower end of the FICO distribution, however, this pattern is reversed. On average, net rewards are far more negative for high-income consumers with low FICO scores than for middle- and low-income consumers with low FICO scores.
>Or, to put that another way: if there is redistribution happening, it necessarily includes redistribution from unsophisticated high income customers to sophisticated low income customers.
While it's true that wealth customers with low FICO scores are getting hosed, it's not clear whether that is enough to cancel out the effect that richer people (presumably) have higher FICO scores on average
The only way I can put these things together is that at the high FICO end, both wealthier and poorer consumers get hosed a lot but wealthier consumers not quite as much. On the other hand, lower FICO band doesn't get as bad of a deal overall but it is worse for wealther people (plausibly because they have high interchange fees and don't use their rewards).
It's complicated, but... this is not a wealth transfer right? It is a transfer mostly just from consumers to credit card companies that provide them a service.
https://news.ycombinator.com/item?id=39928604
Not at many gas stations. Cash gets a discount usually $.10 per gallon. I’ve also started to see restaurants either give a discount for cash, or charge extra for credit card purchases. Business suppliers from tiny shops to large national companies tack on 3% for people paying with credit cards, or like T-Mobile, a $5/line monthly fee in order to get people to pay by direct debit.
The article has one thing mistaken, because it says that Durbin lowered costs for transactions, but credit owners got to keep their perks... That's not technically true (I worked at a supermarket when debit rails first went into effect, and I worked in payments when Durbin went into effect).
There are no benefits to credit users who use the debit rails, and the merchants would really rather you use the debit rails, because it is much cheaper for them. Durbin was mostly a win for the merchants, not a win for the customers.
However, if you take that to believe that the merchants lowered prices overall because they were paying less for transactions, than you might try to read into it that credit users kept their perks, while cash and debit users paid.
The true story, however, is that it's an equilibrium... When the costs go down, the saved money goes somewhere in between the two (supply and demand), and as long as there is competition, the savings are shared.
However, the real problem is that credit companies are allowed to invest interchange fees in perks at all. Credit card companies decided to take their low-risk pool, and offer them incentives, splitting the money they saved between themselves and their users, and using it as a way to pull more low-risk users. The more that happens, the more expensive it becomes for credit companies that serve mid-to-high-risk users... and since we can't stop offering credit to those users as well, those companies push for and get increases to interchange fees to cover the additional cost... which creates more room for benefits for the low-risk users, and the cycle begins anew. It's a vicious cycle that can't be fixed by changing amounts on the existing fee schedule... The only possible fixes would be in either disallowing these kinds of perks, or splitting the rail charges, and specifically charging less interchange for low-risk users (which dries out the benefit pool)
Credit card rewards are not a mechanism to shift wealth towards premium card holders (this is a negligible distraction), they exist purely to increase revenue/conversion rate, by decreasing customer price sensitivity (compared to cash payments) and encouraging financially irresponsible spending. If this did not actually work in practice, every merchant would just insist on cash and pocket the difference.
"Poor people" are hurt much more from the changes in spending behavior induced by credit card use than by paying for card rewards.
I suspect that because I didn't understand what you wrote.
You used a lot of passive voice and complex jargon. That is economists favorite writing style: they write to confuse, not to explain.
No. I do embedded software engineering for a living.
I use (in my view) HN appropriate levels of jargon (because lots of people here are involved with getting people to pay for some newfangled cloud thing or other, so I use their terminology).
In simple words: People pay more for the same (and spend more recklessly) when you let them pay by credit card, and this causes much more economical "damage" to poor peolpe than any "wealth transfer from card rewards".
One consequence of this system is the large merchants have more bargaining power and can negotiate lower fees. So large retailers, gas station chains, etc. are able to reduce the overhead of accepting CC payment. While smaller merchants have the same higher cost.
From a capitalism perspective, this is the most egregious example of "you have capital, so you can make more capital". Banks holding the capital in this case.
Fun fact: when credit cards were first introduced only to people with good credit, which paid the balance in full. this was not profitable. Only after opening the pool to other credit levels did CC start printing money for banks.
This applies to cash as well. It takes a lot of time to count change for everyone. Plus all the ways there are to steal cash.
Your fun fact is wrong. Credit cards were always profitable. They were not in the beginning because scale is what makes them profitable. Anyone who uses their cards for a couple meals a month (which is what it was first started for) is going to cost money because of all the overhead to have you as a customer. In those days that was a stamp to send the bill, someone to open the payment and cash the check - now that everybody works electronically the overhead is lower, plus people are using it for more and so there is enough left over to pay for it.
For merchants, it just doesn't make sense to pay high fees to cater to a dwindling minority of consumers.

Besides, NPCI has introduced merchant transaction fee for UPI now causing decline in UPI transactions.
>The result: People paying cash face the equivalent of a 26% higher sales tax than premium credit card users shopping at the same store.
I am surprised this never occurred to me or has come up at all in discussions with people (in the context of rising costs/inflation specifically). I’ve literally never considered this compounding effect until now. It’s so obvious of course, it just never even crossed my mind.
> equivalent of a 26% higher sales tax than premium credit card users shopping at the same store.
I do not think the sale price is increased by 26% - which doesn’t square with a 1% to 3% fee - I think they pay approximately 26% more in “sales tax” so you’re paying 26% more than the 7% tax.
"It's expensive to be poor" is a more or less universal experience under capitalism and it's amazing how many novel ways we've come up with to make it more expensive for poor people.
"Means testing" is one of the fun ones. The wealthy will often justify this as "People like me shouldn't get this help" which sounds even generous, and then you realise, oh, because we're testing if you're worthy to receive help now to get help you need to expend some time and effort to pass the test. When this "I shouldn't get benefits" is offered to you as a reason to means test, ask them why they're taking a benefit they don't think they should have and why they can't pay society back in other ways rather than inflict more misery on the poor...
It’s a variation on a theme we are all very familiar with. It’s expensive to be poor. But this is another angle I hadn’t really considered. It’s a little more complicated than just “I can have better cards with better benefits.”
TL;DR: The actual cost per item for me is, in very literal and quantifiable terms, lower as a result - and the more expensive things get, the steeper my discount gets while the person next to me paying cash is paying a little more than I am every transaction for the same items.
Put another way: As price/inflation increases, the real number I am saving increases as well. So we aren’t just paying different prices, but their increase is also higher the higher prices get.
US FedNow instant payments went live three years ago, and can move $10M per transaction for a few pennies per transaction.

(A gap in legislation was not mandating offering FedNow capabilities to your customers as a condition of your banking license as a bank; I expect this to be patched eventually)
If my credit card number gets stolen, zero money ever leaves my account. It simply gets contested before the monthly bill is even due, and cancelled. I have probably had number stolen 5 times in 20 years, and its never cost me a cent. Zero dollars every left my accounts even temporarily.
If my debit card number gets stolen, the money is out of my checking account immediately. Mortgage payments and other bill payments might fail, and the onus is on my to chase up the bank to get charges reversed and money returned to my account.

Walmart was one of the larger supporters of FedNow during public comment period, as they experience billions in interchange costs per year, and are building instant payment support into the Walmart Pay component of their app to avoid these costs.

> “It surprised me,” Henry said of adoption of Walmart’s first iteration of pay-by-bank, which is available online but hasn’t been marketed to customers. “It’s certainly surpassed our expectations of the amount of customers that have registered and actually use the payment type.”
> Walmart’s upgraded pay-by-bank offering will be rolled out in 2025. The transactions will occur over bank technology provider Fiserv’s NOW Network, which integrates with The Clearing House’s Real Time Payments network and the Federal Reserve’s FedNow. Until now, large retailers hesitated to launch real time payment options because many banks were not connected to an instant settlement system, meaning their customers would not be able to use the product. NOW Network aims to connect to as many banks as possible to reach 100% of deposit accounts by combining its own network with RTP and FedNow.
My understanding is that Meta is also pushing ad buyers to invoicing vs credit card payment.

Like the slow decline of check volume, I see the same here. Credit card rails will exist for some time, perhaps another 10-15 years, but they have likely peaked from a volume perspective. If you're a merchant, surcharge when you can, and work towards on boarding and offering customers cheaper payment rails (imho). If folks want to pay the ~3-4% surcharge, enable them to, that is a choice if they want the benefits of using a credit card. But we should not all have to eat the cost for their benefit when less expensive options are available.

Credit cards are convenient and cash isn't. The genie is out of the bottle, no way to make people move back to cash.
If interchange fees were capped, people would go back to cash, imo. A lot of research shows you spend less when you pay with cash. And the lack of credit card rewards as a draw might lead people to carry it again

Credit cards have a really high ROI. The 3% drives 10-20% more spend, sometimes even more. When I was on the board of a small private school, we bought a square terminal and used QRs for flyers. That drove 30% increases in fundraiser expenses and helped us reduce mailings and nags. We would cross-sell stuff - could buy your youth soccer registration at the fall fest or whatever.
The things where ach, check, cash make sense are where there’s no discretionary spend at point of sale or recurring payments. If you pay 75 bucks a week that have your apartment cleaned dog groomed or whatever. You’re not getting value beyond taking the payment in advance with a credit card. Those are the areas where Venmo and Cash app have really dominated.
This is even more true of the American brands that are getting Trump to attack modern, open, cost-free systems from other countries—like Brazil's PIX, maintained by the Central Bank of Brazil.
I call it 21st-century American usury.
