Not sure about capping but you'll only receive 0.7 RP per 100 on all days for rent payments and below mentioned merchant categories.I have never used my IndusInd legend signature for house rent, or any other IndusInd card for that matter. I found online it's 0.7 RP per 100 rupees for house rents after devaluation. And for IndusInd it's 2X reward points, so can I expect 1.4%? And is there any capping on this?
