It writes that Scirocco had the bright idea of using infrared technology to transmit information, and to bridge the gap between short-range low-frequency RFID systems and longer-range UHF or active systems. The tags gather energy from the sun or other light sources and continually send out infrared signals that contain a unique 32-bit serial number. The tags can store up to 128 bytes of additional data. The system is immune to most forms of electromagnetic interference. The article mentions that Scirocco hasn’t finalized pricing, but the readers will cost about as much as high-end low-frequency RFID readers, and the tags will be priced competitively with active RFID tags.
