Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically stored information. The passive tags collect energy from a nearby RFID reader's interrogating radio waves and responses to the read request.
Unify IP phones are equipped with a passive RFID chip containing MAC address, part number and production information. The data can be used to automate logistic processes for inventory management.
This page describes the RFID tag in more detail to support partners and customers using that tag for their own purposes.
