RFID Systems

RFID (Radio Frequency Identification) library systems use radio waves to transmit data over short distances. This information contains the identity, location, and/or status of items in the library collection. Fast, easy and efficient, RFID technology eliminates the need for “line of sight”, thus simplifying check-out and check-in operations, materials handling, and inventory management.

EM Systems

EM (Electromagnetic) library systems offer a reliable and versatile way to protect library books, magazines, and AV materials. Our EM systems use DSP (digital signal processing) to ensure accurate, reliable tag detection and are managed over the internet to maintain optimum performance and reduce service costs.

EM or RFID? It can be confusing. Our team regularly offers demonstrations and webinars to help libraries better understand their options.
