Engineering Brief

The Impinj M775 is an advanced UHF RAIN RFID tag chip designed for high-performance item-level tagging applications. It features Impinj's proprietary FastID technology enabling rapid singulation and inventory speeds up to 33% faster than standard Gen 2 chips. With enhanced read sensitivity (approximately -21 dBm) and extended read range, the M775 provides reliable performance in dense tag environments. The chip is optimized for integration into small form-factor inlays suitable for retail, supply chain, and asset tracking applications requiring high-throughput inventory operations.

Typical Applications

  • Retail apparel and item-level tagging
  • Supply chain and logistics tracking
  • Inventory management with high-speed reads
  • Brand authentication and anti-counterfeiting
  • Library and document tracking
  • Asset management and tool tracking
