On Android phones, the NFC reader is usually located in the middle or upper back of the phone.

1) Ensure that NFC is enabled in settings.
2) Grab your Goodz. Wake and unlock your Android.
3) Hold your Goodz against the middle back* of your phone for several seconds.
4) Open the notification that appears, or follow the instructions on webpage that loads to access your content.

* While the NFC reader for most Android phones is usually found in the middle or upper back of the device, because of the variation between manufacturers, in some cases it can be found in other locations. If you are getting no response from holding your Goodz against the middle back of your phone, try slowly sliding it across the entire back, bottom, and top edges of your device until you find your reader and a notification appears.

1) Ensure that you have held your Goodz against your phone's reader for several seconds.
2) On both iOS and Android phones, the camera app can sometimes interfere with NFC reading. Close your camera app and attempt tapping your Goodz again.
3) Confirm that your phone is adequately charged, as the NFC chip in your Goodz relies on power from your phone to establish a connection. Charge your device and try again.
4) Verify that your phone is up to date and running the latest operating system available. 
5) Try restarting your phone and tapping again.
