Pretty wild. Australia's had NPP since 2018. You can send money to somebody's phone number and it's in their bank account instantly.

Has it actually helped anything? B2C is still all credit card or (due to some weird regulation) cash because of the credit card fees being passed on.
Even before that Australia had bank transfers, the US had Paypal and now Zelle.
For nearly 20 years the UK has had "faster payments", free instant transfers, now up to £1m, and while you can't send to a phone number, the routing numbers needed can't be used to withdraw so are generally safe to give to people.
