Engineering Brief

The MIFARE Plus S (MF1SPLUSx0y1) is a contactless smart card IC providing a migration path from MIFARE Classic 1K/4K to AES-128 secured systems. It operates at 13.56 MHz compliant with ISO/IEC 14443 Type A and supports three security levels: Level 0 for personalization, Level 1 for backwards compatibility with MIFARE Classic using CRYPTO1, and Level 3 for full AES-128 authenticated and encrypted operation. Available in 2 kB or 4 kB EEPROM with sector-based memory organization, it supports communication speeds up to 848 kbit/s, multi-sector authentication, multi-block read/write, and features 200,000 write cycles endurance with 10-year data retention at 22°C.

Frequently Asked Questions

What is the difference between MIFARE Plus S and MIFARE Plus X?

MIFARE Plus S supports Security Level 1 with MIFARE Classic CRYPTO1 backward compatibility, while MIFARE Plus X operates only in Security Level 3 with full AES-128 encryption and does not support CRYPTO1 legacy mode.

Is MIFARE Plus backward compatible with MIFARE Classic?

MIFARE Plus S offers backward compatibility with MIFARE Classic 1K/4K through Security Level 1, which uses CRYPTO1 authentication. This enables gradual migration from legacy systems to AES-128 security.

What security levels does MIFARE Plus support?

MIFARE Plus operates in three security levels: Level 0 for chip personalization, Level 1 for MIFARE Classic CRYPTO1 compatibility (S variant only), and Level 3 for full AES-128 authenticated and encrypted communication.

How much memory does the MIFARE Plus have?

MIFARE Plus is available in two memory sizes: 2 kB EEPROM (similar to MIFARE Classic 1K) and 4 kB EEPROM (similar to MIFARE Classic 4K), organized in sector-based structure.

What is the communication speed of MIFARE Plus?

MIFARE Plus supports ISO/IEC 14443 Type A communication at speeds up to 848 kbit/s, significantly faster than the 106 kbit/s of MIFARE Classic, enabling quicker transaction times.

Does MIFARE Plus have Common Criteria certification?

Yes, MIFARE Plus has achieved Common Criteria EAL4+ certification, providing independently verified security assurance for applications requiring high-grade cryptographic protection and physical security.
