MIFARE Plus X Datasheet

Migrate classic contactless smart card systems to the next security level! MF Plus brings benchmark security to mainstream contactless smart card applications. It is the only mainstream IC compatible with MF Classic 1K (MF1ICS50) and MF Classic 4K (MF1ICS70) which offers an upgrade path for existing infrastructure and services.
After the security upgrade, MIFARE Plus uses AES-128 (Advanced Encryption Standard) for authentication, data integrity and encryption. MF Plus is based on open global standards for both air interface and cryptographic methods at the highest security level.
MF Plus is available in two versions: MF Plus X and MF Plus S.
The MF Plus X (MF1PLUSx0y1, described in this data sheet) offers more flexibility to optimize the command flow for speed and confidentiality. It offers a rich feature set including proximity checks against relay attacks.
The MF Plus S (MF1SPLUSx0y1)is the standard version for straight forward migration of MF Classic systems. It is configured to offer high data integrity.
