I'm currently doing a project where ideally I will have multiple objects with RFID tags on them that are placed on top of a Adafruit PN532 RFID Shield connected to a Arduino Uno Wifi Rev 2. The idea is that once a button is pressed the RFID reader will read a Mifare tag then "ignore" it then reads the next tag until all are read. How can I acheive this?
I have read some about Anti-collision protocols and the limitations of RFID but was also wondering if it might be possible to read a tag then hold or ignore that tag until it leaves the range of the RFID shield?
I've also read a user on the Adafruit forums had some luck by altering the library that is used, I'll link it for reference, but I've tried the same method but had no luck myself. Adafruit-PN532 Library
I'm new to Arduino so I apologise if I've messed anything out.
Thanks for any help!
