Nokia Lumia 920 - What can I do if my Lumia phone cannot read or write NFC tags?

  1. Go to Settings > select tap+send > On to allow the NFC sharing on your phone.
  2. Make sure that the Home screen is active on your phone.
  3. Find where the NFC antenna is located on your phone and on the pairing device (often indicated by an NFC icon). Place the NFC antennas as close together as possible, and then move the phone slowly over the pairing device surface where the NFC antenna is located. When you hear the connecting sound, the connection is established; you no longer need to hold them together. 
  4. If you order NFC tags, check that they support the NDEF standard and the tags are already formatted. You will not be able to write to a tag that has not been formatted.
  5. Note also that Battery Saver or Flight mode can limit the NFC communication.
