If you have valid rental agreement, register in Redgiraffe along with your landlord details. Once approved, it is like a biller. You can then use Payzapp or HDFC netbanking to send money to the biller using CC. It will have some charges from redgiraffe which I think is 0.5% +GST.
Most CC don't earn reward points or getting additional charges from card issuer. So check the benefits vs cost and do the rent payment by credit card.
