Bank card hacking techniques are becoming increasingly sophisticated, and criminals can withdraw all of your money in just a few seconds. Therefore, customers need to be vigilant and proactive in applying measures to protect their cards as soon as they detect any unusual signs.

According to the recommendation of Joint Stock Commercial Bank for Foreign Trade of Vietnam (Vietcombank), customers need to proactively temporarily lock their cards through 5 common methods when detecting irregularities in transactions or when the card is lost.

Method 1: Lock card on digital banking

Customers log in to the VCB Digibank application, select Manage card services and perform the Card Lock operation.

Method 2 : Lock the card by sending SMS to the operator

To lock the card by SMS, customers can enter the following syntax for each card type:

If you do not remember the specific syntax, customers compose a message with the syntax VCB HELP and send it to the switchboard 6167 for instructions.

The bank card is only successfully locked when the customer receives a response message with the content "Your card has been temporarily locked".

Method 3: Lock card via automatic switchboard

Customers can lock their cards by calling 1900545413, pressing 1 >> 1 >> 1 and following the instructions.

Method 4 : Lock the card via the 24/7 customer support center

Customers can connect directly with the operator at 1900545413 to request card locking.

Method 5 : Lock the card at the transaction counter

Customers go directly to Vietcombank transaction points nationwide to request to lock the card. Bank staff will assist you in locking the card after verifying the information.

If you need direct support, customers can go to any Vietcombank transaction point to request card locking.

Vietcombank encourages customers to prioritize locking their cards via VCB Digibank or SMS to ensure the card is locked quickly and conveniently.

After confirming that their card is safe, customers can re-open the card for immediate use on VCB Digibank (by logging into VCB Digibank >> Manage card services >> Unlock card) or go directly to Vietcombank transaction points nationwide.

The 5 ways to lock bank cards in an emergency are commonly used today.

In addition, some banks also provide other services to support customers in blocking cards in emergency cases, such as:

- Automatic card locking service : The card will be automatically locked after a number of incorrect PIN entries or after making an unusual transaction.

- Transaction notification service : The bank will send you an SMS or email after each transaction is made on your card.

Please note that card blocking is only effective for a certain period of time. After this period, the customer's card will be automatically unlocked.

For more information about bank card blocking support services, customers should contact the bank where they opened the card.
