Dynamic Security Code

A dynamic security code, accessible through the NBS Mobile Banking app is another way we help give you greater protection against fraudulent transactions. The dynamic security code is valid for just 24 hours before it expires. It can be used when shopping online instead of the three digit code (sometimes known as CVC or CVV) on the back of your card. This makes your card details useless to scammers who may have intercepted older card data.

The three digit temporary code works in the same way as the three digit code printed on the back of your physical card – only it changes every time you access your card details in the NBS Mobile Banking app. You can use this number when completing online transactions instead of the code on the back of your NBS Debit Mastercard®.

Because the code is only valid for a 24 hour period, it provides greater protection should your card details be stolen online.

Greater protection

The three-digit dynamic security code expires 24 hours after being viewed. This helps to reduce fraudulent transactions if your card details are stolen online. By the time a fraudster attempts to use your card, the code will have expired and the fraudulent transaction will fail.

Convenient

Carry out online transactions all from the NBS Mobile Banking app without the need of your physical card.

Secure

All your details are safely secured in the NBS Mobile Banking app.

When completing an online transaction, instead of entering the three digit code from the back of your physical card, you can enter the dynamic security code found within the NBS Mobile Banking app. If you don’t have a mobile device with you at the time of your transaction, you can still use the code printed on the back of your card.

Use the dynamic security code for online purchases or when you first set up a recurring payment eg, signing up for a subscription.
