You have to remember to pay back your credit card debt before the clock runs out. Once you make a UPI payment the transaction ends there (because the money is debited from your bank account and you are not taking on a conditional loan). You don't have to remember to pay the UPI company anything after the fact. I hope this explains how UPI is different from credit cards.

In my experience paying with credit is a fire and forget action, since the money is debited automatically at the end of the month, with no interest. The UX is great, since it only takes a card swipe [as long as I have the funds to pay it back and I'm within my credit limit].

In an scenario where you are not debited right away, I agree completely. But I would only expect that to happen by accident or if the user lacks the financial literacy to understand there are better ways to buy whatever they want. I may be missing some financial corner cases.

I don’t remember when was the last time I’ve paid my credit card, I’ve set it on auto pay. Plus I accumulate enough points at the end of the year for one way trip to India.
