Impinj M700 Series RAIN RFID Tag Chips with Extended Memory

Impinj M780 and M781 RAIN RFID tag chips have large memory banks and advanced features that enable reliable storage, access, and monitoring of item attribute data — increasing item visibility, reducing waste, and improving consumer safety.


Store extended item data in a dependable, large-memory tag chip

As part of the Impinj M700 series, the Impinj M780 and M781 provide industry-leading performance, features, and manufacturability while enabling customers to expand RAIN programs into new and emerging markets. Ideal for pharmaceutical, food, industrial, and manufacturing applications, these large memory capacity tag chips are designed for capturing extended product attributes such as batch/lot numbers, dates, net weight, or use-by dates. The Impinj M780 and M781 support current GS1 tag encoding recommendations, including the recently announced EPC Tag Data Standard (TDS) v2.0, so supply chain partners can easily pinpoint products of a specific lot or batch for recall and monitor expiry dates to ensure older products ship and are used first. 


Reliable performance at a greater distance for harder-to-read applications

Extend read range with best-in-class read sensitivity to capture more items of a RAIN RFID system with these reliable, powerful tag chips. Impinj AutoTune V2 adaptive tuning optimizes tag performance and allows reads on more materials and in difficult environments. An Impinj-exclusive portfolio of Core3D Antenna reference designs enable omnidirectional reads, eliminating blind spots and improving accuracy. Ensure consistent and accurate data delivery with the Impinj Integra V2 memory diagnostics suite.


Digital transformation at scale with proven manufacturing technology

The Impinj M780 and M781 build upon proven Impinj M700 manufacturing technology. The M780 and M781 help optimize tag chip production, enabling high-volume applications and growth into emerging markets. The Impinj Enduro V2 bonding pad allows for easier manufacturability and outstanding durability over the lifespan of a tag.

Impinj tag chip features
for high performance RAIN RFID tags

Protected Mode tag data protection

Impinj Protected Mode makes a RAIN tag invisible to RAIN readers. The tag can be returned to normal operation, and made visible to RAIN readers, using a secure PIN

Enduro V2 bonding technology 

Updated Impinj Enduro bonding pad design provides optimal mechanical stability and assembly consistency for improved tag yield, reliability, and durability

FastID high-speed reading

Reduce inventory time by simplifying the steps needed to identify a tag when using a TID-based numbering system

AutoTune V2 adaptive RF tuning 

Impinj AutoTune optimizes performance to the tag’s environment for improved readability across a range of materials, tag form factors, and operating frequencies  

Integra V2 memory diagnostics 

Suite of diagnostics verify tag chip health and validate data encoding to consistently deliver more accurate data and reliable tags  

TagFocus read redundancy prevention 

Unique algorithm prevents multiple reads of the same chip so that hard-to-read tags can be read more accurately within a complex population of tags  


Why use Impinj M700 series chips

Impinj M700 series tag chips bring game-changing advancements to RAIN RFID. Ideal for large-scale, global deployments, Impinj M700 tag chips deliver high-performance, quality, and reliability.  

  • Read items faster, from farther away: improved tag readability enables items to be read at longer distances, and read faster to reduce inventory time and improve productivity
  • Support next-generation RAIN solutions: new capabilities enable innovative solutions for consumer privacy, anti-counterfeiting, loss prevention, and embedded tagging
  • Tag options for all items: allows for small, universal tags that can operate worldwide, simplifying the tag supply chain for a global enterprise
