I already have the HDFC Platinum Debit card right now, but I recently was upgraded to HDFC bank's Imperia programme. I was wondering if I should apply for Platinum Imperia debit card. I checked bank's pages of both cards, and couldn't find any difference, except that the Imperia one has a different colour and Imperia written on it. The insurance cover of both cards are also same. Is there any difference at all?
