Overview

Impinj Gen2X is a standards-compatible enhancement to the RAIN RFID protocol (GS1 UHF Gen2 / ISO/IEC 18000-63) that advances RFID system performance, efficiency, and security. Designed for enterprise and consumer RFID deployments, Gen2X expands the capabilities of existing RAIN RFID systems by accelerating inventory counts, increasing tag read range and accuracy, reducing stray reads, improving read-zone control, inhibiting item and tag counterfeiting, addressing consumer privacy, and lowering total solution cost. It operates seamlessly with existing Gen2 systems while unlocking previously difficult or unsolvable use cases across retail, logistics, manufacturing, and healthcare.

Features and Capabilities

• Performance Enhancements: Improves reader sensitivity and power delivery to tags, enabling faster inventory counts and superior readability for small or hard-to-read tags.
• Inventory Speed: Reduces communication errors and tag backscatter data to significantly accelerate inventory processes.
• Tag Read Range: Extends the effective read range of RAIN RFID tags.
• Tag Decluttering: Discriminates tag responses to help readers distinguish between simultaneous tag replies and reduce stray reads in dense environments.
• Tag Filtering: Ensures only tags of interest participate in an inventory round, improving accuracy.
• Protection & Security: Inhibits tag and item counterfeiting, enhances consumer privacy at point-of-sale, and adds verification capabilities to secure authentic tags.
• Cost Reduction: Reduces solution and labor costs by improving detection reliability, reducing false reads, and enabling new use cases like automated or self-checkout.
• Compatibility: Backward-compatible with existing RAIN systems and broadly supported by tags and readers using Impinj M800 series endpoint ICs and E-family reader chips.
