It took some time but RuPay branded CCs are also available. I have been using them for the last 2-3 years at least. They work, mostly, with UPI.

Some merchants disable RuPay CC payments even when they don't get charged merchant fees till the payment crosses the INR 2K threshold.

Strangest thing is when I can pay the guy pushing a handcart around selling vegetables using a RuPay CC while a medical store refuses to accept it.
