How to Block GTBank ATM Card Using USSD

Given the high prevalence of cybercrime, it is critical to remain secure. The ATM card can be used to withdraw money from a machine.

It works similarly to a credit card, except that when a transaction is made, money is sent straight from the cardholder’s bank account.

What is an ATM Card?

A bank-issued ATM card allows cardholders to conduct transactions at ATMs, POS terminals, and online.

This means that if a criminal has access to your ATM card, they will be able to take your money with them.

Security information, such as a 16-digit unique card number, is included on every ATM card, including the expiration date, name of the cardholder, and a three-digit authorization code, such as CVVC or CVV.

If a criminal gains access to that security information, they can take your money even if they don’t know your 4-digit transaction PIN.

You can block your ATM card by entering a shortcode on your phone if it is stolen, forcibly seized, or you suspect the security information has been hacked.
