Use the following steps to troubleshoot your device:
- Make sure that you have turned on NFC on your device.
- Position your YubiKey NEO as close to the NFC antenna (of your device) as you can and hold it there for two to three seconds. Due to the small size of the YubiKey NEO and its own antenna, the YubiKey NEO needs to be very close to the NFC antenna of the device.
- If the YubiKey NEO registers but does not work, log a support ticket with Yubico and include the tag information. To do this, download the Android app called TagInfo by NXP. Scan your YubiKey NEO and attach the data (you can export it via email or other means) when you raise the ticket with Yubico Support.
- If your YubiKey still does not work, attempt to test your YubiKey NEO with another NFC-capable device and/or test your NFC-capable device with an NFC tag before you raise a ticket with Yubico Support.
