ICODE SLIX-S vs Tag-it HF-I Plus

Choose ICODE SLIX-S if your application requires Electronic Article Surveillance (EAS) functionality, Application Family Identifier (AFI) filtering, or privacy mode features for retail and library environments. This chip provides 112 bytes of user memory organized in 32 blocks of 4 bytes each, operating at 13.56 MHz with ISO/IEC 15693 and ISO/IEC 18000-3 compliance. The SLIX-S includes 32-bit password protection for EAS and AFI functions, plus a lock mechanism for DSFID, AFI, and EAS registers. With data rates up to 53 kbit/s and block-level write protection, it suits scenarios where inventory management and theft prevention must coexist, such as bookstores, libraries, and retail chains requiring both item tracking and gate alarm integration. The 64-bit read-only UID provides unique identification for each tag. Choose Tag-it HF-I Plus if your primary requirement is larger memory capacity for storing more extensive item data. This chip offers 256 bytes of user memory in 64 blocks of 32 bits each—more than double the SLIX-S capacity—making it suitable for applications requiring detailed product information, maintenance records, or multi-field data storage. Operating at 13.56 MHz with ISO/IEC 15693 and ISO/IEC 18000-3 protocols, it provides individual block locking through both user-programmable and factory lock bits, allowing granular control over which data fields remain writable versus permanently locked. The factory-programmed and locked 64-bit UID ensures permanent unique identification. This chip fits supply chain applications, asset management systems, and industrial tracking where data richness matters more than retail-specific features like EAS, though it lacks the dedicated anti-theft and privacy functions of the SLIX-S.
