Check your card's expiration date. If it is about to expire and you are registered for TDB Online, you can log in, go to the Cards -> Order Card section, select your preferred card type, and place a new order. If you are not registered for TDB Online, you can request a new card by calling the bank's hotline at 1800-1977 from your registered phone number, or by visiting any nearby branch with a valid national ID or passport. If you are located abroad, please send your card order request to [email protected] using your registered email address.
If you have a credit card or a card with an active credit line, make sure to check the loan repayment deadline, the credit line expiration date, and the card expiry date.

To protect against potential risks, you may register a joint account holder or an authorized representative with the bank for your card.
It is also a good idea to test your card at an ATM or a point of sale to ensure it is functioning properly.
