This can happen if your phone treats the hardware key as a generic NFC tag instead of triggering the intended action (e.g., FIDO2 authentication).  
  
**How to Fix This Issue**

  

1.  **Don’t open the NFC tag notification.** Instead:
2.  Open the app or service where you’re trying to use the key (e.g., the Xapo Bank app).
3.  Retry tapping your security key while the app is active.
4.  **Ensure you’re using the correct app workflow.**
5.  In Xapo Bank, make sure you’ve navigated to **Settings > Security > Security Keys > Add Security Key** before tapping your key.
6.  **Hold the key in place for a few seconds.** Sometimes, NFC devices need a moment to register correctly.

If none of the above resolves your issue, it may be because your device does not support FIDO2 authentication via NFC. Try using a USB-C cable to connect your device to your mobile phone and see if that resolves the problem.
