When adding a card, your bank may ask you to confirm the action using 3-D Secure (3DS). This protects you from unauthorized card use.
Common Errors
- “Authentication failed”
- “Your card is not registered for 3-D Secure”
- “Please register your card through your bank’s app”
- “Card not registered for online purchases”
These mean your card isn’t activated for 3DS or the confirmation didn’t go through.
Affected Users
- DebiX cardholders (especially via the debiX+ app)
- Older cards never used online
- Customers not using their bank’s app for confirmations
Your card is not blocked — it just needs 3DS activation.
How to Solve It
- Open your bank’s app or online banking.
- Activate 3-D Secure / Visa Secure / Mastercard Identity Check / Online payments for your card.
- Return to our app and try adding your card again.
- DebiX users: Make sure your card is linked in debiX+ and use your One Time Registration Code (OTRC) from your registration letter.
Still Having Trouble?
Contact your bank and ask:
“Can you confirm or make sure my card is activated for online payments or 3-D Secure?”
After that, adding your card should work.
