RFID uses radio waves to identify and track objects. RFID is a generic term that encompasses different frequencies and standards, including both NFC and RAIN.


What is RFID?

Radio Frequency Identification (RFID) is a form of wireless communication that uses radio waves to identify and find objects. RFID is a generic term that encompasses different frequencies and standards, including both NFC and RAIN — two technologies supported by industry alliances. In simple terms, all RFID systems operate on the same principle: An RFID tag stores information that can be read wirelessly by an RFID reader.

What is RAIN RFID?

RAIN RFID is a passive, battery-free wireless technology that connects billions of everyday items to the internet. RAIN is a name that brands passive UHF RFID products and technologies that adhere to global standards. RAIN RFID systems enable businesses and consumers to identify, locate, authenticate, and engage with every item that’s tagged with a RAIN RFID tag, providing rich, real-time data and insight. RAIN RFID is used in a wide variety of applications, including inventory management, asset tracking, and shipment verification. 

RAIN is the fastest growing segment of the RFID market and uses a single, global standard: UHF Gen 2 (ISO/IEC 18000-63). RAIN has connected billions items to date. By providing internet connectivity to, and real-time information about, everyday items such as apparel, medical supplies, automobile parts, food, and more, RAIN RFID enables the true Internet of Things.

What does RAIN RFID do?

RAIN RFID can connect everything in your everyday life — from socks to strawberries to shipping pallets. It digitizes the physical world. With RAIN RFID, a system can automatically sense what is happening, share related data, and respond. RAIN RFID provides 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

RAIN RFID can identify and locate up to 1,000 items per second without direct line-of-sight.


Why use RAIN RFID?

RAIN RFID has the capacity to greatly enhance people’s lives while revolutionizing the way companies do business. It is a flexible, low-cost solution, making it appealing to a wide range of industries — from retail to healthcare, manufacturing to hospitality.

RAIN RFID can tell you what an object is, where it is, and even its condition. With this information, businesses around the world are able to increase sales, drive operational efficiencies, and improve customer experience. Solutions range from supply chain management to asset tracking to authentication of frequently counterfeited pharmaceuticals. Applications are limited only by your imagination.
