LEGIC advant ATC1024 / ATC4096 vs MIFARE DESFire EV1

Choose LEGIC advant ATC1024 / ATC4096 if you need flexibility between ISO 15693 and ISO 14443A protocols in a single product family, or require LEGIC proprietary encryption and Master-Token System-Control for legacy system integration. The ATC1024-MV110 offers 944 bytes with ISO 15693 and 64-bit key data transfer encryption, while the ATC4096-MP311 provides 4096 bytes with ISO 14443A, 3DES data transfer encryption, and AES-128/256 storage encryption. Both variants support 3DES/DES/LEGIC data storage encryption, making them suitable for environments already using LEGIC infrastructure. The ATC4096-MP311 variant is Common Criteria EAL4+ certified and supports multi-application systems with proprietary LEGIC controls. Choose MIFARE DESFire EV1 if you need a widely standardized ISO 14443A solution with broader vendor interoperability and flexible memory options. Available in 2 kB, 4 kB, or 8 kB EEPROM configurations, DESFire EV1 supports up to 28 applications with 32 files per application using full ISO/IEC 14443-4 compliance and optional ISO/IEC 7816-4 commands. Security includes 3DES with 56/112/168-bit keys, AES-128, mutual three-pass authentication, 8-byte CMAC, hardware exception sensors, and optional Random ID anti-cloning features. All variants are Common Criteria EAL4+ certified with RF channel data encryption. DESFire EV1 is the better choice for transport ticketing, access control deployments requiring broad ecosystem support, or projects where avoiding vendor-specific encryption schemes matters.
