How to lock and unlock payment cards and credit cards

Debit cards and credit cards are very convenient financial tools, making it easy to make purchases, pay bills, and manage expenses. However, like any financial tool, debit and credit cards also carry risks if not carefully protected. One important measure to ensure personal financial security is to lock and unlock the card when necessary.

Block payment/credit cards

Nowadays, most banks offer online banking apps on mobile phones, allowing you to easily block your card when needed. To block a card via the banking app, simply log in, select the credit card or debit card section, and then choose the block option. Some banks offer the option to temporarily or permanently block your card, giving you more flexibility in managing your card.

Although the steps for blocking credit or debit cards vary between banks, the process is similar. You just need to follow the instructions on your bank's app to complete the card blocking process.

If you are unable to access your bank's app, you can also contact your bank's customer service directly to request that your card be blocked. You need to call the customer service phone number (usually printed on the back of the card), provide your personal information and card details for identity verification, then request that the card be blocked and provide a specific reason.

Unlock payment/credit card

Similar to locking a card, unlocking a card can also be done through the bank's mobile app, customer service, or Internet Banking. To unlock a card via the bank app, simply log in to the app, select the credit card or debit card section, and then choose the card unlock option.

If you are unable to access your bank's app, you can contact your bank's customer service to request card unlocking, providing your personal information and card details for identity verification.

You can also use Internet Banking to unlock your card by logging into your account, selecting the credit card or debit card option, and choosing the card unlock option.

When locking and unlocking your card, remember to carefully verify your information to ensure security. Always keep your card information and personal data secure to prevent misuse by fraudsters. If you lose your card, contact your bank immediately to block it and avoid the risk of misuse.
