First, offline only works when an institution chooses to extend credit to the user. That's not nearly as widespread in other countries as it is in the US. Second, QR codes don't need a battery either. Third, having someone send money (i.e. authenticated user actively tells their provider/network to send money) is far superior to having merchants take money (i.e. charge a CC, even over NFC, even with temporary CC numbers).
- amaccuish 5y agoNot necessarily. Debit cards in the UK can be trusted to work offline as certain "ceiling" is saved to the card with nearly every transaction, saying ok the owner has 10.000 in the bank, they probably have enough to cover a 4 GBP coffee (yes it's still technically credit but really?)
- jfrunyon 5y agoExactly. As you said, that is credit. And it is not available to consumers in most other countries.
