Banks have introduced many ways to block and unblock your debit card. Read on to find out the different ways through which you can block and unblock ATM card.
Why Blocking a Debit Card is Necessary?
Blocking a debit card becomes necessary in the following situations.
- Stolen card: If someone steals your wallet, which has all your debit and credit cards, then you must immediately block your card to prevent its misuse.
- Misplaced card: If you misplaced your debit card and can’t find it, then it is best to block it. Even if you find it later, you can always unblock it or get a new card reissued.
- Unauthorised payments: If you find an unfamiliar transaction on your debit card which you didn’t initiate, then your debit card details could be compromised. In such cases, you must immediately block your debit card without delay.
- Failed attempts of card usage: If you receive messages of failed attempts to withdraw cash at an ATM, which you did not initiate, then your debit card is in the wrong hands. You must immediately block your card.

Sometimes, the bank blocks your debit card automatically in certain cases. The following are some of the common reasons why the bank will block your card automatically.
- The bank will block your old ATM card after you activate the new ATM card.
- If there is a security breach, then the bank will automatically block your card and reissue a new card.
- Whenever the bank suspects fraudulent activity, it will either confirm with the user or block the debit card automatically.
