Since RBI has allowed Rupay cards to be linked with UPI, does anyone know how we can link our Rupay cards on apps like PhonePe, Amazon Pay and Paytm? I am iPhone user and so far not spotted any options on any of these apps to pay someone using cards via UPI. Is this something which is yet to be implemented by the UPI apps or roll outs have already begun. Any timelines for the iOS users?
