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.

My board : wemos d1 mini

please guide me

Did it work? I have an Android phone HCE it keeps giving a random ID how can I know the user/device which has tapped?
