Hi, I am using the pn532 module
My wiring and connection to the module is through the software serial
When I hold the mobile phone in front of this module, it displays a different UID each time.
I want to use a mobile phone instead of a card and each phone has a unique ID so I can identify who this mobile phone is for.
please guide me
