IDK about you, but QR payments here aren’t just for those who have bank accounts. Majority of non-bank eWallet apps also have integrated with this QR system, and they have their own account numbers and QR that works like a bank account, and anyone can register it entirely through the apps. Even lower-spec and older smartphones can still run those bank/eWallet apps here just fine, as long those smartphones are not rooted.

Yep, I said that.
They can go to any 7-Eleven stores to reload their cash into the app. Some other convenience stores offer such service too.
