Migrate classic contactless smart card systems to the next security level! MIFARE Plus brings benchmark security to mainstream contactless smart card applications. It is the only mainstream IC compatible with MIFARE Classic 1K (MF1ICS50) and MIFARE Classic 4K (MF1ICS70) 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 (MF1SPLUSx0y1, 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 (MF1PLUSx0y1) offers more flexibility to optimize the command flow for speed and confidentiality. It offers a rich feature set including proximity checks against relay attacks.
