Farsens has announced the Photon RFID tag, equipped with a bright LED, which operates as a UHF RF field detector tag. Whenever the tag comes close to an RF field source, it harvests energy from the RF field and drives its LED according to the field's strength, stated the company.

The stronger the RF field in a specific point and orientation, the brighter the LED illuminates. Built in a PCB format, the tag has a detection range up to 3m for UHF RFID readers.

Photon tags can be used to assess the status of aging RFID implementations. RFID reader and reader antennas deployed several years ago may not perform correctly. The devices help users assess how good the system is performing. Such RF field detectors can also be used to signal activities to users. Entering a specific area may require a certain set of procedures from the user. A sparkling LED could act as a visual indicator and reminder.
