LEGIC advant ATC1024 / ATC4096 vs MIFARE Plus EV2

Choose LEGIC advant ATC1024 / ATC4096 if you need dual-protocol flexibility across different infrastructure types or require deployment in mixed environments. The ATC1024-MV110 variant operates on ISO 15693 with 944 bytes memory and 64-bit key data transfer encryption plus 3DES/DES/LEGIC storage encryption, while the ATC4096-MP311 variant runs ISO 14443A with 4096 bytes memory, 3DES data transfer encryption, and AES-128/256 storage encryption options. Both variants include Master-Token System-Control (MTSC) for hierarchical access management, and the ATC4096-MP311 achieves Common Criteria EAL4+ certification. This family suits multi-application systems where different readers or legacy infrastructure must coexist, or where the 4096-byte capacity of the ATC4096-MP311 is required for storing diverse credentials and data. Choose MIFARE Plus EV2 if you require the highest security certification available in contactless smartcards or need transaction-level integrity protection. Operating at 13.56 MHz on ISO/IEC 14443-A Type A, ISO/IEC 14443-4, and ISO/IEC 7816-4 protocols, MIFARE Plus EV2 offers 2 kB or 4 kB non-volatile memory organized in sectors with 16-byte blocks. It provides AES-128 authentication and encryption, 3DES support, ECC-based NXP Originality Signature, and achieves Common Criteria EAL5+ certification—a higher assurance level than the ATC4096-MP311's EAL4+. The Transaction MAC (TMAC) feature ensures transaction integrity, anti-tearing mechanisms protect data during power loss, and Random ID support prevents tracking. Available in 17 pF or 70 pF input capacitance variants for antenna matching flexibility, MIFARE Plus EV2 is the better choice for high-security access control, payment systems, or government applications demanding rigorous security certification and transaction verification.
