The party is over. HDFC has sent an email to all credit card holders. Capping on reward points given on rent payment services has started.
The maximum caps become effective from 23/07/2022.
The Caps are different for different cards.
The monthly rent you can still pay and get points is sufficient for most users.
This news makes BOB Eterna credit card that much more sought after. But I expect the same move will be replicated by other credit card issuers too.
