Install a NFC Tag Writing App
We recommend using either NFC Tools or NFC TagWriter by NXP.
1.Once you've installed the app on your phone, open the app and select "Write".
This should bring you through to the next screen which should allow you to select "New Dataset" or "Add a Record".
Here you can input various fields of data to write to your tag.
After you are finished inputting all of the data that you wish to write, save your data and move onto writing.
Write the Tag
5.Now you can press the "Write" button and the app should prompt you to hold your NFC card up to the phone.
Hold the card up to the back of your phone and wait for the app to confirm that the data has been successfully written onto the card.
You can then test your NFC card by tapping it against your phone and waiting for it trigger a prompt.
The reader should be on the upper half of the phone.
The reader can either be on the center or the upper half, depending on the model.
