I don't know how much you know about payments in India, but they are, from what I have heard, fairly evolved and advance.

In fact, in India there are 4 different ways in which you can do online transfers across the banks (NEFT, RTGS, IMPS, and UPI). The latest iteration, UPI, is indeed state-of-art. It lets even companies like Amazon, Google, and PhonePe, which are not traditionally banks, to offer ability for people to do transfers from their Bank account. QR Code for UPI apps are very commonplace at least in metros and it enables nano transactions without really a fee to small merchants and users. There are lot of fail safe mechanisms and safety features built into the protocol and a user is not really hostage to the bank or the payment app as you can switch both at your will.
