Enable SCA for your SumUp Card

  1. Log in to the SumUp App on the phone you will use to approve payments and ensure the app is up to date.

  2. Select “Account” on the Home screen.

  3. Tap the settings symbol in the top corner then choose “Account Security”.

  4. Enable Strong Customer Authentication by tapping on the toggle.

  5. You'll receive an SMS with a unique verification code, enter the code into the “Phone Verification” section of the app and press “Confirm”.

If, after enabling SCA, your transaction still fails, check for common causes of transaction failure. Alternatively, consider contacting the online shop owner or using a different payment method.

Important:

These security measures became mandatory for online payments as of March 2021.

Set up biometric confirmation and notifications

To make the SCA feature faster and more secure, you can enable authentication with your fingerprint or face ID to do this, tap on the “Touch ID” toggle button in the “Card Security” section.
