Repository of all the ways to pay credit card bills and get rewards.

Hi,

In this discussion, I am trying to make a repository of all the options to pay credit card bills to get max rewards.

Some of the ways that I know:

1. HDFC Easy Shop Platinum Debit Card VISA ONLY (1%): We get 1% as cashback max 750/month for paying cc bills on bill pay. (Limitations: HDFC cc bill cannot be paid there)

2. Mobikwik UPI (0.4%): CCPAY can be used to collect supercash (2% supercash) and then it can be used. (100 supercash is right now equal to 20 Rs)

3. HDFC Millenia debit card (1%): We get cashback upto 400 via Paytm wallet load and then paying your CC bill through Paytm Wallet. {Credits: Knight11)

4. SBI debit card (0.25%): Rewards for paying CC Bill. {Credits: pjain2712}

Please, comment any other method to earn rewards, I will append the list.
(Requesting all comment only verified options)

Thanks
