I recently purchased the RFID RC522 reader/writer,along with some NFC Mifare classic 1K 13.56mhz tags. The seller on Amazon mentioned that the NFC tags were compatible with the rc522 reader/writer; however, I have not been able scan the tags. I was wondering, is it really possible to scan NFC tags with the RC522 reader/writer? thanks nfc tags RFID RC522 module

Is it partially true. Depends on the NFC tag you're using, there are 4 different NFC tags types working in different protocol technologies. You can check it in the following link.

As I can see in the specs, RC522 supports ISO14443A and all variants of MIFARE products.

If I'm not wrong (long time not working with NFC):

  • Type 1: You can't scan those tags
  • Type 2: You can scan those tags (based on Mifare Ultralight)
  • Type 3: You can't scan those tags
  • Type 4: You can scan some, not all, of those tags (partially based on Mifare DESFire)

As Type 2 and Type 4 NFC tags are based on MIFARE tags in general you should be able to scan those type of tags.
