bro but how will you set money

bro when the device is scanned you will enter the amount enter a pin and make a payment

so bro this is very innovative idea but..

but ...?

brother see there is many software that can be make video or something that can be scan and also cctv is for pin hacking therefore the shopkeeper or any hacker can hack this easily but I have solution of it

bro what's why we have a unique pin like upi pin which will only know by the user

bro I said cctv there is no prospective you say that it only done by user phone you say that it done by a device so on the device consumer write pin that can be easily trackable
