ICODE 3 vs Tag-it HF-I Plus

Choose ICODE 3 if you require advanced security features and higher memory capacity. It provides 2432 bits (304 bytes) of user memory across 76 blocks compared to the Tag-it's 256 bytes, giving you 48 additional bytes for application data. The ICODE 3 offers dual-layer password protection with both 32-bit and 64-bit passwords, ECC-based originality signatures using secp128r1 (either 32 or 48 bytes), and two privacy modes for data protection. Its granular security includes block-level and page-level locking, password-protected EAS/AFI features, and a destroy command for end-of-life scenarios. The chip supports both ISO/IEC 15693-2 and ISO/IEC 15693-3 protocols and includes a dedicated 24-bit counter in block 75 plus 192 bytes of configuration memory, making it suitable for supply chain authentication, pharmaceutical tracking, and applications requiring cryptographic verification of authenticity. Choose Tag-it HF-I Plus if you need a straightforward ISO 15693/ISO 18000-3 solution for basic item tracking without complex security requirements. With 2048 bits (256 bytes) organized in 64 blocks of 32 bits each, it provides sufficient EEPROM memory for standard identification and inventory applications. Security is limited to individual block locking using user and factory lock bits, plus a factory-programmed and locked 64-bit UID for basic identification. The Tag-it HF-I Plus operates at 13.56 MHz and meets both ISO 15693 and ISO 18000-3 standards, making it compatible with standard library systems, asset tracking, and access control where encrypted authentication is not required. This chip is cost-effective for high-volume deployments in retail tagging, document management, and general logistics where read/write functionality and permanent locking are adequate but cryptographic security is unnecessary.
