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! :D
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 :)
