To change your payment card PIN code, go to the app, select Cards, select the card for which you wish to change the PIN and click on Change PIN code.
Bear in mind that PIN changes can be done when using the MobileSCAN PIN, TouchID, FaceID, or code calculators to log in to the app, but not when using code cards.
Click Create new PIN
and enter your new PIN twice.
Confirm by entering your MobileSCAN PIN code.
You must then enter the card with the changed PIN code into any bank’s ATM (in Latvia or abroad, in any, where the card chip is read) and perform any operation, such as viewing your balance or withdrawing cash.
Your PIN code will only be confirmed once the card has been entered into an ATM.
