@JustMak I suggest do your research that'll only make you good at this
Thanks. I have some fair understanding, but was hoping if someone may have already worked out the finer details, and can share their experience for everyone benefit.
Anyways my high-level understanding:
HDFC Infinia Metal:
Earn 5 RP per ₹150 spent on retail transactions
Earn up to 10x RP on travel and shopping spends on the Smartbuy platform, with a monthly cap of 15,000 bonus RP
Earn 3x RP on some purchases, like train ticket
1x base RP with a monthly cap of 200,000 base RP
HDFC DCB Metal:
Earn 5 RP per ₹150 spent on retail transactions
Earn 2x RP per ₹150 spent on retail, insurance, utilities, and education transactions
Earn 5x RP on travel and shopping spends on the Smartbuy platform, with a monthly cap of 15,000 bonus RP
1x base RP with a monthly cap of 75,000 base RP
HDFC Biz Black Metal:
Earn 5 RP per ₹150 spent on retail transactions
Earn 5x RP on select business categories like office supplies, telecom, and IT services, with monthly cap of 7,500 bonus RP
1x base RP with a monthly cap not specified
So in summary, the Infinia Metal offers the highest earning potential with 10x and 5x multipliers, while the Biz Black Metal is tailored more for business expenses with its 5x category. The DCB Metal sits in the middle. All have monthly caps on bonus RP earnings.
Please feel free to add more details or correct any of the above details, so all can learn and make the most of these cards. Thanks!
