03 Nov NFC aka RFID implant used for unlocking phone
Video showing how small NFC/RFID implant works as a key to my phone.
Phone is Sony Xperia M4 Aqua Dual with Android 5.0
Should work with most Android phone which have NFC connections and it’s built option to recognize NFC keys.
Go to Setting – Security – Smart Lock – Trusted Devices and set it up
