Can NFC Tags be encrypted?

Only some NFC chips support hardware encryption encoding. Below are the most common chips, with relative cryptography supported.

  • MIFARE® DESFire® (DES, 2K3DES, 3K3DES, AES)
  • NXP ICODE® DNA (AES 128 bit)
  • MIFARE Ultralight® C (3DES)
  • NTAG® 4xx DNA (AES-based CMAC)
  • MIFARE Classic® (not safe, not recommended)
