TECNO L9 AND L9 PLUS - WILL LAST LONGER THAN YOUR BOYFRIEND 

 

Most transactions using the code 737 are fast and it can be done at the comfort of your home, by just using the last four (4) digits of his ATM card. YES!!! The last 4 digits of your ATM card and you’re the line you register with the bank is all you need.

Using just the last 4 digits of your ATM card isn't secure enough because anyone who steals your phone and wallet (where your bank card is likely to be) can use the service to clear off all your hard-earned cash.

GTBank has now made the service more secure. The service now requires a 4-digit PIN of your own to be able to complete transactions on the platform. That is certainly a more secure approach to the service than the previous use of your ATM card’s last 4 digits.

According to the instructions on GTBank’s website,

    Dial *737*5# on the phone number that is linked to your account.

You will be asked for your 4-digit PIN to complete any transactions on the service, so do not forget it.
