MIFARE Plus® S 4K Card

MIFARE Plus^® provides end-user solution providers with a seamless upgrade of existing infrastructure and services with low cost procedures. This new MIFARE product has been developed and supported by card and reader manufacturers and solution developers. and is the only MIFARE Classic-compatible mainstream smart card IC featuring pre-issuance of cards prior to infrastructure changes.

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.
