This is what my country's government went with instead of dealing with the platforms. Since the likes of Apple and Google don't care about the country, and the old local banks doesn't care about tech, we have many e-wallet apps rising, and they use QR codes. But that creates fragmentation, so the central bank decided to standardized all the QR code payments so anybody use the same one, including the banks. This only involves the payment gateways, banks, and the e-wallet apps. No need to worry about Apple/Google hardware/NFC. Seems to be working out great so far.
