Why Should You Block a Lost or Stolen Card?

If your card is missing, blocking it quickly can help prevent unauthorized transactions. Someone who gets access to your card details may try to misuse it for payments or other activities.

By blocking your card, you can:

• Stop further transactions from that card
• Reduce the chances of financial loss
• Keep your bank account more secure
• Request a replacement card if needed

Most banks allow users to block their cards without visiting a branch. You can usually do this through official banking apps, internet banking, SMS, or customer care services.
