Instead of having payment systems that seem to go out of their way to make it inconvenient to pay, there should be a small number of very well defined friction points (such as: “maximum daily expenditure”) with literally zero friction anywhere else. By now for instance we should really have a security technology that allows anyone to spend $5 a day any way they want, in any denomination (e.g. literally 2 cents here and 2 cents there), without having to go through ridiculous virtual-cash systems, cards and other hoops. The money should simply be there, and it should be able to go anywhere. If it’s a relatively small amount, it doesn’t require a lot of gate-keeping, e.g. you do not need a customer-refunds infrastructure or fraud protection scheme for pennies. The money can then either reset automatically, e.g. each day, or after some explicit more-secure action, e.g. you log in to something with your face. I know that it would personally make me spend a lot more if a lot of transactions could “just happen”. Once I got a tap-here-and-pay watch, I spent more. Once I could shop online with a fingerprint, I actually did shop online. When I had to type in credit card details though, I hardly ever wanted to. When “fees” would appear as part of seemingly-small transactions, I hardly ever wanted to continue. Some things just sound like scams (don’t get me started on subscriptions), making me more likely to find an exit.
