It shows option to pay using "Tata Pay UPI". When I select it, then in the next page, it shows my Neu Infinity Rupay card greyed out with the message "Rupay Credit card payment is not allowed for this merchant".
As an aside, I am feeling that the coins are of no use for me especially given the fact that I stay where there is no BigBasket and I don't have medicine need usually. I thought may be if I somehow accumulate some points, I might purchase some silver coin but unfortunately the Neu coins cannot be used for that. To add to it, Neu coins earned during a transaction seem to have an expiry of 3 months I guess. Any suggestions on how the coins can be used?
