There are several options infront of you. The best would be to block the existing card and request a new one.Login to DBS app. Under debit Card section, you get an option to block the existing card. After you block the old one, request a new card through the same channel. Good thing is, they don't charge money for card replacements.In my view, DBS Bank is the bank of the future. The benifits include Unlimited ATM withdrawals, no minimum balance requirement, paperless and it just requires aadhar number and pan number to open accounts.
