If the wallet will not accept your card, these checks usually solve it:
- Confirm the card is active and not frozen, and that the card details you entered are correct.
- Make sure the billing address matches the information saved in the app.
- Confirm your device, account, and region support the wallet you are using.
- Update the wallet app and your device software, then try again.
- If verification keeps failing, save the error message and contact U9 Card support.
Once your card is added, you can use it in online or contactless payments wherever that digital wallet is supported. Apple Pay or Google Pay may charge a 0.2% fee, which is shown on the actual payment screen.
