About the Company

Impinj

RFID hardware and software for item tracking

Impinj provides an end-to-end RAIN RFID platform that lets businesses wirelessly connect everyday items to computers and the Internet. Its offerings include RFID tag chips, readers, gateways, and software that together let companies identify, locate, and verify items in real time across environments like retail, healthcare, manufacturing, and logistics. The product works by tagging items with passive RFID chips; readers and gateways collect tag signals and transmit data to software that inventories, tracks locations, and authenticates items. Impinj stands out by delivering an integrated hardware-software ecosystem (chips, readers, gateways, and management software) and a licensing/sales model that supports end-to-end RFID deployments. Its goal is to help customers improve inventory accuracy, reduce operating costs, and enhance customer experiences through better visibility and automation in the supply chain and other operations.
