Mainstream contactless smart card IC for fast and easy
Rev. 3.2 — 21 February 2011
Product short data sheet
1. General description
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 infrastructure and
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 X and MIFARE Plus S.
• The MIFARE 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 MIFARE Plus S (MF1SPLUSx0y1)is the standard version for straight forward
migration of MIFARE Classic systems. It is configured to offer high data integrity.
