MRFC522 chip and Arduino library use only chip ID of card for authentication. Anyways, current cards support MIFARE Classic algorithm, which is broken. Therefore, the current level of security of the solution is low, especially against technically-savy users in a FabLab environment.

Improvements can be done but will require substantial efforts:

  • member cards need to be updated with more robust chips
  • MRFC522 chip needs to be replaced with PN532 or similar
  • cryptography library is needed (one implementation is available in MitteFab : https://git.mittelab.org/proj/keycard-access )
