I generally pay my rent (more like adding money to my bank account) using Cred and Paytm. They charge around 1.8% inc GST. But last month, I exhausted the monthly limit on Cred. Paytm was taking two days to deposit money. So I used Phonepe to pay rent for the first time. They charge 1.9% to 2% inc GST. But I was surprised to receive reward points on my transaction. I hold a diners club privilege card. I think this loophole can be explored until they fix it, especially post the recent devaluation. I'm attaching an SS for reference.
