Most of those negatives sound fine to me.

Yeah, like what’s wrong with cash?

America doesn’t really have a functional system for this yet either. It’s a lot easier to just tap your phone on a brick and be done with it, but currently the tap method is pretty hit or miss. And bank transfers are atrocious - why do we pay venmo to do something that Korean banks just straight up do for everyone? In Korea you can just give someone your deposit number and with a couple buttons you send money easily/instantly.

You don’t even have to go that far, Canada has interac e-transfers where you can send money by email. Directly accessible through the standard bank app/site. I haven’t handled cash in years

Ew email does not sound like the place for cash transactions.

But yeah, most countries these days have instant bank transfers. The US is ancient when it comes to payments, “cashing your payslip” isn’t a thing in much of the rest of the world.
