General Description

MIFARE and MIFARE Plus are registered trademarks of NXP B.V. and are used under license.
MIFARE® Plus brings benchmark security to mainstream contactless smart card applications. It is the only mainstream IC compatible with MIFARE® Classic 1K (MF1 IC S50) and MIFARE® Classic 4K (MF1 IC S70) which offers an upgrade path for existing infrastructures and services.

After the security upgrade, MIFARE® Plus uses AES-128 (Advanced Encryption Standard) for authentication, data integrity and encryption. MIFARE® Plus is based on open global standards for both air interface and cryptographic methods at the highest security level.

MIFARE® Plus is available in two versions: MIFARE® Plus S and MIFARE® Plus X.

The MIFARE® Plus S (MF1 S PLUS x 0y1, described in this data sheet) is the standard version for straight forward migration of MIFARE® Classic systems. It is configured to offer high data integrity.

The MIFARE Plus X (MF1 PLUS x 0y1) offers more flexibility to optimize the command flow for speed and confidentiality. It offers a rich feature set including proximity checks against relay attacks.
