    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.)

      Level 2/3 data: https://docs.adyen.com/payment-methods/cards/enhanced-scheme...

      It's only available in the US, many countries have lower interchange fees and prohibit sending this data.

      This would explain why so many damn coffee shops dont deal with cash now - the double as a coffee shop and data reseller

        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.

      I would love if it was transmitted to the bank for my own use so I can easily remember what I purchased or run budgeting software against it! Obviously wouldn't be pumped about it being resold tho.

        It's crazy it is resold but we don't even get it for our own use. Budgeting with credit card statements would instantly become so much more useful with less effort.

        Amex provides more data directly to the customer, if this is relevant. Unfortunately, I believe they also resell it.

    >The merchant pays 2.5%

    The best way to pay for poor services already rendered and move on with life is to simply pay via card. Didn't like that haircut? Terrible food at the restaurant? Hold onto your cash and slip them the card.

    • tonymet 14 minutes ago
      Jokes on you. Merchants prefer credit cards because there is less loss than cash. 2.5% is nothing compared to 5-10% loss at the register. Plus easier and more accurate accounting.
      • 1970-01-01 10 minutes ago
        If you're expecting 10% loss at the register and have terrible service, that's a 1-2 punch for bankruptcy.

    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.

      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.

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

        Walmart is currently trialing it to save billions of dollars 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.

      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.

    > The issuing bank keeps 2%

    Is this why the best cash back credit cards give 2%?

    • dmoy 9 minutes ago
      US Bank for a brief period opened up a 4% card, but then closed it so quick that obviously the numbers didn't work out there.

      2% seems to be a local maximum of cashback cards. There's a lot of 2% cards, and only a handful above that.

      Makes sense?

    > Use this knowledge to topple the Visa/Mastercard duopoly and design your own payment method.

    You can’t, because Uncle Sam will come after you.

      The answer to that is to "donate" to about 270 congress critters. Buying 5 motorhomes for supreme court members could work too.

    Don’t forget arbitrage, which is the withholding of transferred funds for 7 days while the capital remains in visa’s accounts for “investing” / speculation.

    It’s like if you gave your buddy $100 to give to his room mate, and he decides to wait a week and gamble it on Kalshi

    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.

    • tonymet 12 minutes ago
      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.
    • tialaramex 38 minutes ago
      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.

      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.

        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)

      > 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.
