I can't seem to get this going.
I have the Adafruit PN532 RFID/NFC Shield (Product No. 789) and an Arduino Uno R3.
All I would like to do is compare the "unique" 4-byte ID of a tag with a predefined ID.
It would be great if anyone had any code to help me out to make this work in the most basic manner
Nothing too fancy!
I'm OK at coding but don't quite understand how the IDs are stored...
I feel really dumb and am probably missing something really obvious.
If anyone could help me out I would greatly appreciate it
