They tax our entire economy at X rate, while maintaining their infrastructure only requires Y cost ... and X is significantly higher than Y.

From the actual article:

> The payment processor keeps 0.35% ($0.35), then pays 2% ($2.00) to the cardholder’s issuing bank and 0.15% ($0.15) to Visa. The 2% is the interchange fee, commonly known as interchange. The 0.15% is the network assessment fee. 8

In other words, they get 0.35% of every transaction ... and it does not require anything close to that to maintain their network.

If it's so easy to disrupt visa/mastercard payment network, they wouldn't be able to charge this much. Payment is a highly competitive business. We witnessed so many payment companies went under or were bought out, but these two stay for years and are still profitable.

The truth is their moat is considered very durable and hard to build. A global n banks to n banks payment network is not as simple as how people thought.

Credit card companies are mostly parasitic middle men but I have a credit card that I use for most payments and pay off the balance every month and effectively get 2% cashback with no interest costs.

losteric 2 hours ago | parent

The actual rates charged to merchants are variable, and typically higher for rewards/cashback cards. Basically, other people are subsidizing cards with higher benefits/cash back (of course as people shift, the merchant raises prices to compensate for the higher average fee, or just charge an additional Z% higher than your cash back)

tialaramex 2 hours ago | parent

That 0.35% feels more reasonable in 1976 or even maybe 2001 than it does today because technology changed so much. But maybe I'm wrong about that

If you're an American that 2% is a much bigger problem for your society. That's a direct funnel from the poor to the wealthy, it's not as a obvious a problem as "Trump gave the ultra-rich a tax cut" but it might structurally be more significant.

Goods (and services) are priced at what the customer is willing to pay. In this case, the alternative is cash or cheques, both have much higher loss rates. That’s why vendors are eager to take visa over cash.

I remember reading a comment here a while back about merchants being offered a discount on the processing fee if they also transmitted detailed data about the purchase (essentially the data that would be on the receipt). That data could then be resold on to advertisers. Does anyone remember this or have links to more data? (Not having much luck with search, maybe I'm hallucinating the whole thing.)

I mean, cash is also expensive in its own way. It has to be handled and insured, coins may need to be rolled before being taken to the bank, a register is a mechanical device to power and maintain, petty theft by employees is a concern.

It's not really that hard to see why a business charging $5-20 per transaction from people who all have phones and credit cards anyway might choose not to accept cash.

smelendez 1 hour ago | parent

Well, they still pay a fee, it’s just reduced.

They primarily don’t deal with cash because cash is a pain. It needs to be physically taken to a bank and protected from theft by both staff and random robbers with guns, it needs to be counted all the time, and you need to maintain the right denominations to make change.

I have reservations about businesses getting rid of cash, especially if they’re turning away people who don’t have alternative ways to pay, but I certainly understand why they do it.

It’s also always awkward when a coffee shop is like 95% credit, and you try to hand them cash and they look at you like you’re Rip Van Winkle.

Note the wording on dollar bills:

See also USC §5103:

Thus a private person is only obligated to accept cash as repayment for a debt, not for purchases.

the main purpose of that data is for fraud detection, anything downstream (i.e. selling it to advertisers) is just the cherry on top. Merchants are always financially incentivized both implicitly and explicitly to do anything that would reduce fraud and increase the rate of successful authorizations.

collabs 2 hours ago | parent

In my opinion, the only solution is everyone (individuals as well as corporations) gets a direct account with the federal reserve as long as you can associate a taxpayer identification with the account. Using it is voluntary but it is free of cost, paid for by taxes, and moving money to and from accounts is free of cost. Depositors would get the same overnight interest rate that banks do, and this interest is added every day. I think if we could make this happen, the chokehold of Mastercard and Visa can be greatly diminished. The disintermediation of commercial banks, the loss of credit card perks, and the added cost of customer service should be an acceptable cost of removing the parasites visa and master card from our economy.

most importantly, this opens up a lot of money that the federal reserve can hold directly, something that will become more and more important as bond yields go sky high.

How are chargebacks resolved in this situation?

This is an important question- most of the costs of a credit card providers come from dealing with fraud and chargebacks. That's partially because, under US law, credit card companies have to eat fraudulent charges if they can't get the person or company that did the fraud to do so. (Funnily enough, this is one of two places where protections for average people in the US are significantly better than protections for average people in Europe).

But credit card companies can keep their costs low by making a business decision not to renew the accounts of frequent chargeback-ers or chargeback-ees (even if they never officially found those individuals at fault). If the government had to make a payment system for everyone and take on all responsibility for all fraud, that would create an incentive with massive second-order effects.

toomuchtodo 1 hour ago | parent

Customers can pay the credit card fee to get their chargeback insurance, if they choose, while others who can pay with cheaper instant payment rails can opt out. This is trivial with merchants able to surcharge credit card payments, as many merchants are starting to do (US mobile phone companies, US internet providers, Meta ad purchases, restaurants, etc).

mopsi 1 hour ago | parent

You resolve it the same way you handle in-store cash purchases of products that turn out to be faulty.

There is no reason why fraud and contract violation must be handled by unelected and unaccountable payment processor, when the government has already set up a consumer protection system for disputes related to cash payments. The payment processor is best left as a dumb pipe that does what parties and (in case of disputes) courts tell it to do.

diegocg 1 hour ago | parent

So the article shows how visa and mastercard are, by far, not the ones taking the largest fee, and the solution is to get rid of them?

Where are you going to do the transactions in your scheme? Because credit card transactions are not the same as sending money from one bank account to another. There are settlements, disputes, chargebacks, etc.

How is the central bank going to offer the same variety of products described in the article? I.e..

> Interchange fees vary dramatically based on the kind of card, category of spend, and even the metadata attached to a transaction. The network’s goal is to set fees that incentivize desired behaviors on their network, including using more secure payment methods (lowering interchange fees for merchants), or for companies to do more business spending (higher interchange fees on commercial credit cards).

Your scheme sounds like all these crypto guys who think they can replace credit cards with bitcoin transactions, as if they were the same thing

Central bank instant payment system. The US has FedNow, and has had it for almost 3 years. It costs a few pennies to move up to $10M per XML message.

Brazil's Pix costs ~$10M/year to run: https://whatispix.com/

This is much cheaper than the entire credit card ecosystem skimming ~3% off of the economy. Efficiency!

FedNow Is Live - https://news.ycombinator.com/item?id=36801491 - July 2023 (1022 comments)

Walmart is currently trialing it to save $3B-$7B a year in interchange fees. No crypto, just XML messages through a mainframe at the Federal Reserve with a 20 second SLA.

> “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.

Where I am it's increasingly common to see credit card fees when checking out. I get it, because merchants are being charged 3-5% of their total revenue.

There is, it's called debit cards, but Stripe et al. "simplified" pricing by charging a percentage regardless of card type instead of the traditional interchange-plus pricing. Merchant banks "used to" make money by tacking on fixed fees, i.e. a set-up fee, terminal fee, monthly fee, etc, but then Stripe came along and provided (1) a better dev experience, (2) better onboarding, and (3) simplified pricing.

You have to wait for the investigation to complete to receive compensation if you’re hit by fraud on a debit card. Credit cards don’t share that issue. If you’re poor or living paycheck-to-paycheck, debit cards are potentially a risk to your livelihood.

seabre 6 minutes ago | parent

As someone who has been hit with fraud on a debit card and a credit card, the process to recover money from fraud on a credit card is so much easier and more hassle-free than a debit card.

The big difference is that with a debit card, it's your money that is hit by fraud. The debit card is basically just a proxy. You have to go file a police report. You have to hope the bank will give you the money back.

When the credit card gets hit, it's the credit card company's money and they will seemingly chase the fraud to the ends of the earth to recover it.

I use a cashback card, because most merchants will charge me the same regardless of payment method, and getting a 4% discount (+ time value of money) is the lowest cost to me. If I use some other payment method, the merchant may keep more of the transaction amount, and that's great for them, but it doesn't improve my customer experience. If interchange fees are strictly capped and cashback cards disappear, I wouldn't be upset; but while they're here, I'm incentivized to use them... following economic incentives while doing economic transactions seems like the right thing to do?

Another thing to consider is your credit card rewards cash back etc are really trading your privacy for a little rounding error worth of discount in comparison to using cash.

You may also save far more money going cash only. E.g. some local restaurants near me give you like 5% off paying in cash. Gas is generally cheaper cash price vs card price or debit fee. You have a big job with a contractor, tell them you might be interested in paying cash and they might offer you a substantial discount.

Contractors, but also cosmetic health work. Invisalign, veneers, plastic surgery, etc. Probably most big-ticket items or services that you're not buying from a megacorp.

In a theoretical sense, you are right.

The life of most currency notes is bank to customer to merchant to bank, and the bank could just track serial numbers to figure out your spending habits.

Practically, it would make little sense. The actual life of most currency notes is bank1 to customer to merchant to bank2, and there is a large probability that bank1 and bank2 are different entities. And then, so many more people use the credit card system, and it is so much easier to track people there, that the ROI on tracking people using cash would be low.

I would be very surprised if any bank tried to scan currency note serial numbers.

I used to think "I should be nice to merchants" and pay everything in cash.

That was 15 years ago. Now, living costs have gone up, I'm getting taxed to death by not just governments but increasingly more by businesses themselves ("benefits fees", "installation fee", "convenience fee", guilt-tip screens, sneaky price increases, etc.) so now I feel no guilt in playing the system to get at least some of my money back. Now I just churn 1-2 credit cards a year to pay my taxes and get some of it back in the massive sign up bonuses, which more than cover the transaction costs, fees, and then get me another few thousand back.

If merchants across the world make a deal with me to charge exactly the listed/advertised number exactly, no more, no less, then I'll pay in cash again.

Deal? No? Okay, you continue paying your merchant fees and I'll continue reaping the credit card bonuses to the maximum possible.

That is only "nicer" as it allows to evade taxes. (Which some may consider nice)

But cost for cash is comparable to card payment if looked at seriously

* You need working time to count it

* You need working time to bring to bank (or request pickup, which costs)

* The bank will charge the deposit

* The bank will charge for the change you need

* In the shop the cash has to be protected (safe? Protection against robbery)

* This requires procedures for shift change etc (thus training time and prolonging working time)

* There is a risk of fraud (counterfeit, swap tricks etc.)

* Employees might have sticky fingers

I would only use cash in situations where I'm able to obtain a discount compared to using a credit card.

Even then, you have to think twice. If you get scammed of cash, it's gone. If you get scammed in a credit card transaction, there is a fighting chance you can dispute the charge and have it reversed in their face.

You know that credit card feature of providing some insurance coverage on things like vehicle rentals? It may look like small print, but I actually used that. By some amazing fluke, I damaged the bumper of a rental car; the credit card coverage took care of it. I filled out minor paperwork and never heard about the issue.

Speaking of rentals, in many rental situations (even simple power tools at your Home Depot or whatever) you get charged a deposit on the card which comes back when you return the thing. It's just a number in database. With cash, you'd have to fork that up over the counter; very unappealing.

That's what systems like Pix fixes. It's managed by the state, it's low cost and it's universal... which is why the US is against it so hard.

It boggles my mind that the government has privatized currency to these people.

Crazy-person-but-actually-really practical-idea:

Nationalize one if these networks. Maybe Discover.

The US government should provide us digital currency. The simplest way is to force the current systems to do that. All that rent they collect in terms of transactions fees shouldn't be profit for a private business but fees of the government.

Discover was JUST purchased by Capital One, so I think they'd hate for it to be nationalized

Well I don't really know what they do, but what I know is that Visa transactions costs are 0,22 € out of a payment of 1 €, Mastercard's is 0,23 €, and the French CB network is 0,17 €.

All of them do the same : ensure I get the money from the customer. Of course it's a larger project to run this in the whole world, but shouldn't it scale to less along with the number of billions of customers instead of the other way round ?

This is an insane amount of money. They killed micro-transactions, they killed the business model of the Web in favor of ads, the only popular way to do microtransactions right now.

They charge you 23%?

I thought in the EU the maximum interchange fee for consumer credit cards is capped at 0.3% of the transaction value.

Plus fixed fees.

I don't want to put responsability on anyone, I don't know who takes what in the chain, but I see the fees in practice.

I took the cheapest PSP I could find in Europe... Stripe is way more expensive, taking 25 cents of fixed fee !
