Some users already got 4% ER on fuel spend via UPI + 1% fuel spend wavier (Axis IOCL RuPay CC link UPI).
Note - As I've said it 1000 times, now I'm saying it for the 1001st times. 😜😜 Credit on UPI is new, all merchants/fuel merchants are currently not registered under fuel spend UPI MCC code. It will take upto 2 years to register under correct UPI MCC code. Banks are also getting UPI spend data, they will analyze it and put it on their credit card software.
