             | Now he keeps one set of books, and raised his average sale

             | Ditto with a non-profit I was on the board of. Pushing
             | Venmo and Square for donations increased donations by like

           | What many people in Germany want is a payment system that is
           | as anonymous and is as hard to control by some untrusted
           | entitity (both government and banks are very distrusted) as
           | possible and what cash offers. That's basically cash.
           | 
           | Not without reason, in Germany there exists the well-known
           | phrase "Bargeld ist gelebte Freiheit" ("cash is lived

             | online.
             | 
             | Any other payment method will not give customers any
             | benefits over those methods. Unless banks are willing to
             | take responsibility for fraud like with card purchases.

         | 
         | The merchant's system displays this code, you open your online
         | banking app, scan the code, select "SEPA INST" (here's the
         | usability catch!) to make the payment instantaneous, and
         | confirm. Within 10 seconds, the money is transferred to the
         | merchant's account. Either the merchant's bank or a third-party
         | Open Banking API immediately informs the merchant's system
         | (e.g. by push notification or webhook), and a receipt is
         | issued.
         | 
         | Everything is already here, but since this system would be
         | virtually free to use, nobody really has an incentive to push

       | Sure, but merchants are raising prices overall together with all
       | their competitors, or charging more when using a card. Credit
       | cards aren't taking away 12% of merchants' profits that they'd
       | keep otherwise.
       | 
       | Also, credit card fees are not 4%, they're 1.5-3.5% with an

       | But what's missing here is fraud protection. It's more like debit
       | cards than credit cards, and debit card transactions are much
       | cheaper in the US too (more like 0.7%).
       | 
       | Now that it's increasingly common for local merchants to
       | implement a credit card surcharge (so non-CC users don't have to
       | pay more), and a large percentage of credit card fees come
       | straight back to the user as rewards (e.g. a 2% cash reward),
       | it's not really clear that payment fees matter all that much in
       | the end. See:

         | And they're much lower than that in the UK and EU. Even the

         | 
         | That depends on the market. Suppose you're selling something
         | which has a substitute available for the same price, so the
         | customer will buy whichever one costs less by any amount, but
         | the substitute is in a different market where the payment is in
         | the form of a bank transfer or it's a tax deduction etc., or
         | the substitute is paid for in time rather than money.
         | 
         | Then none of the sellers accepting credit cards can raise the
         | price because otherwise the buyer would go to the substitute.
         | 
         | And all markets are like that _to some extent_. For some the
         | seller can 't raise the price by a cent without losing 100% of
         | their sales. For others, raising the price would "only" cost
         | them 5% of their sales... but that's still 5% of their sales
         | gone, and all the same fixed costs to cover. And, of course, in
         | the cases where the price goes up, now it's the customer eating
         | the fees, which is fairly nefarious when it's being subtly
         | hidden from them.

         | Stripe is 2.9% + $0.30. For a $10 transaction, that's 5.9%. For
         | a $3 transaction it's 12.9% -- of revenue, not profit.

         | 
         | "Fraud protection" is is independent of the fees. You're making
         | the case for that yourself -- if 86% of the fees go to rewards
         | programs then they could be reduced by 86% without affecting
         | "fraud protection", and the rewards programs are a wretched
         | thicket of dark patterns and unpaid interest scams taking
         | advantage of people who are bad at math or too short on time to
         | configure them efficiently, on top of a tax on lower income
         | people who don't qualify for them.
         | 
         | It's also not clear why "fraud protection" should cost
         | _anything_. The bank has no meaningful way to investigate a low
         | dollar amount he-said she-said and the high dollar amount ones
         | should be going to the actual court system, so why should they
         | have anything more than a set of rules (e.g. which transactions
         | are eligible, how long you have to file a dispute) under which
         | you can make a request to have them flip the bits back in their
         | computer for free?
