MIFARE Ultralight AES is a cost-effective contactless smart IC card launched by NXP, designed for limited use cases (such as transportation ticketing and hotel access control). It features AES-128 encryption and enhanced security mechanisms, and has the following characteristics: I. Security Features AES-128 Encryption Authentication: Supports two-way three-stage authentication, dynamically generates session keys, and prevents unauthorized access. Negative Authentication Protection: Optional 24-bit one-way counter and command counter limit the number of invalid authentication attempts. Data Integrity Protection: Verifies communication messages via CMAC (Cipher-based MAC) to prevent tampering. Key Locking: Supports a write-protected AES key storage mechanism, compatible with traditional CRYPTO1 keys. II. Performance and Compatibility Storage Capacity: 144 bytes of EEPROM user memory, supports 100,000 write operations per cycle. Communication Protocol: Compliant with ISO/IEC 14443 A-2/-3 standard, operating frequency 13.56MHz, transmission rate 106 kbit/s, read distance up to 10cm. Compatibility: Memory structure is the same as the previous generation MIFARE Ultralight series, facilitating system upgrades. Supports random IDs and 7-byte UIDs for enhanced privacy protection. III. Application Scenarios Transportation Ticketing: Replaces paper tickets/QR codes, supports single-journey tickets, multi-journey tickets, and event tickets Hotel Access Control: Integrates with the Assa Abloy Vingard lock system, providing secure access control to guest rooms and facilities. Membership Cards/Small-Amount Payments: Suitable for low-cost, high-security, limited-use scenarios.
