Monza 4 Series vs SIC4310

Choose Impinj Monza 4 Series if you need proprietary performance optimization features like TagFocus for directional read sensitivity, FastID for accelerated inventory operations, or BlastWrite for rapid programming during tag manufacturing. The Monza 4 operates in the 860–960 MHz UHF band with EPC Class 1 Gen 2 V2 compliance per ISO/IEC 18000-63, offering 128 bits of EPC memory, 512 bits of user memory, and 64 bits of TID. Security includes standard 32-bit access and kill passwords, plus AutoTune and Self-Adjust technologies that dynamically optimize tag performance across varying RF environments. These features make Monza 4 suitable for high-throughput retail and supply chain applications where read speed and tag-to-reader distance matter, especially when working with Impinj reader infrastructure that can leverage the proprietary extensions. Choose Silicon Craft SIC4310 if you require enhanced Gen2v2 security features, specifically EPC Gen2v2 cryptographic authentication and Untraceable command support for privacy-sensitive applications. The SIC4310 operates in the same 860–960 MHz UHF range with identical memory allocation: 128 bits EPC, 512 bits user memory, and 64 bits TID. It provides full EPC Class 1 Gen2 v2 compliance per ISO/IEC 18000-63 with the same basic 32-bit access and kill passwords as Monza 4. The key differentiator is the inclusion of Gen2v2 authentication capabilities and Untraceable command, which allow temporary hiding of tag data to prevent unauthorized tracking—critical for consumer privacy regulations and anti-counterfeiting deployments. The SIC4310 emphasizes high sensitivity for extended read range in asset tracking and inventory management, making it appropriate for general UHF RFID deployments prioritizing standards-based security over vendor-specific performance enhancements.
