An effective illustration is a stack of tagged playing cards, where HF has a 100% read rate, if you stacked 52 cards on top of one another, a UHF antenna could not read even one card when similarly stacked on top of one another.

The problem that surfaced is that some of the RC522 card readers won’t read some cards (Including the OV-chipkaart). That’s obviously a problem when the door won’t open or the machine won’t start, or your project using those card readers doesn’t work with all the cards it should be working with.

Step-1: Change the RST pin to 5 if you are using Arduino Uno or use RST pin 9 in Arduino Mega. the other pins remains the same. Step-2:Download AddicoreRFID library. I have tried the cards that came with the device, cards that I got from a previous RC522 that arrived broken, and cards I got from hotels. I have both the small round keychain cards and the white credit card sized ones, and neither will read.
