HDFC bank will soon launch RuPay credit card linked UPI, within a few weeks or months.
Canara bank will also launch RuPay credit card linked UPI.
Axis bank is also interested.
As of now only these 3 banks are interested to launch RuPay credit card linked with UPI.
You should know, all new UPI features start with BHIM UPI app and then other 3rd party UPI apps will launch.
Wait 6 to 8 months, you will see other UPI apps will also launch RuPay credit card linked with UPI feature.
