Upgrading HDFC credit card does not have any co-relation
with the reward points. If you are a HDFC credit card holder you can upgrade
from your current card to another card. You can download the credit card
upgrade form from the bank’s official website, fill it up and submit it to the
nearest bank.
The upgrade is decided at the sole discretion of the bank
and you will be given any existing credit card product. Once your upgrade
application is approved, you will be sent a new credit card which has new
features. Features from the old card will no longer be valid. You cannot switch
back to the old credit card after upgrading to a new card.
