What is RAIN


RAIN Technology

RAIN is a standards-based, wireless technology that connects trillions of everyday items to the internet, enabling businesses and consumers to identify, locate, authenticate, and engage each item.

RAIN is the fastest-growing segment of the RFID market, with over 1 billion RAIN chips shipped every week in 2024! To date, this powerful technology has connected hundreds of billions of items, providing the ability to:

  • Uniquely identify individual items beyond just their product type
  • Identify and locate items without direct line-of-sight
  • Identify many items quickly (up to 1,000 items per second)
  • Read items within a range of between a few centimeters to several meters

In simple terms, RAIN is a technology that uses a reader to read and write a tagged item, manage the data, and take action. RAIN provides rich, real-time data and insights for various applications, including inventory management, asset tracking, and supply chain optimization across many industry sectors.

A RAIN system is a standards-based, wireless system where the tags and readers both implement the RAIN air-interface protocol and the tags are encoded utilizing controlled numbering practices, either following applicable ISO standards or the GS1 EPC TDS.

RAIN Tags

  • Are either attached to or embedded in items, with a noticeable trend towards embedded tags in certain market segments
  • Tags store and send information
  • Thousands can be identified simultaneously, and do not have to be visible

RAIN Readers

  • Have antenna(s) for either short or long-range communication
  • Can be small and portable, or larger and installed, or embedded in other devices
  • Game-changing developments are happening in this space as the RAIN Alliance leads the whole ecosystem towards a future where RAIN readers will be available in consumer handsets, and our end users recognize the massive power of “always on” RAIN systems over other technologies

RAIN Software applications

  • RAIN software systems use the data collected from RAIN tags to Identify – Locate – Authenticate – Engage with items, and create massive business value from the accurate and timely data collected
  • Increasingly trending towards AI-based intelligent systems, RAIN software applications are seen proving value at “the edge,” in the cloud, and deployed in end-user environments, depending on the sector in question.
