Earlier quoted context omitted.
Crappy payments isn't a tech problem, it's a market problem. Consumers and merchants can't be bothered to adopt contactless technologies that were introduced half a decade ago. Companies have tried QR codes and other payment schemes long before that (including the unfortunately named ISIS), but again, no traction.
Americans don’t like contactless payment? Or (more Likely), unlike their Chinese counterparts, American banks are way more conservative with adopting new technologies. Hence why y’all still get paid with paper cheques :)
Nobody gets paid with paper checks unless they want to, although if you're poor and have been blacklisted by the bank system you might take it so you can use a check cashing service.
