Nah, india has UPI which uses QR codes.
Madness!
Why?
Even a low-end phone comes with a good enough camera for QR which means wider adoption, you need a higher tier phone for NFC.
We have a similar system in my country and I believe we copy it from India, it works and is convenient.
Because 0 security
What? Payments are obviously going to be secure.
QR codes cannot contain enough data to put cryptographic keys.
Okay? QR codes are displayed publicly. They display the unique ID of the merchant. That's all. The payment happens over the internet which is encrypted.
Lol what?
Isnt it free and very good?
Think of it more is visa master card discover bank of America?
Yep.
As in "free" payment processing system deployed and maintained by the Indian government?
Why the quotes? It is free. Except for the money that you transfer. That is deducted from the bank account, obviously.
Taxpayers still pay for it, but it is free at the point of sale or transaction.
It is great system tho as far as my understanding how it was done. In us, the rate is 3-4% on credit transaction which dominat payment system for point of sale. Shit is taxing.
The real question is why do people in the US use credit cards instead of debit cards like everyone else?
It provides better customer protections over any other payment method. It allows you get a charge back if vendor is acting funny.
You zero practical protection with cash for example if physical or less protection with debit card. Debit cards are not good to use for everyday buying if it is your checking account. It is too risky.
Many countries have laws and regulations which create customer protections, so there's no need to rely on 3rd party solutions.
Good luck enforcing shit in a US court against a "private enterprise" and you sure as fuck can't count on any regulator here for anything beyond some good lip service.
Smart move is to go based on how system functions, not how it supposed to work. It is likely configured for this anyway.
Use case where possible folks, they are taking it away as is.
