IPICO’s Dual Frequency RFID Technology uses the same IP-X multi-read protocol as its UHF products, but the low
frequencies used, (125kHz power-up and 6.8MHz return signal), can penetrate through “lossy” media without the problems
of tag antenna detuning, and the high attenuation encountered with UHF systems. Because of the high tag transmit carrier
frequency, high data rates are achievable (up to 256kbit/sec), resulting in fast reading of multiple tags in the beam. Dual
Frequency technology allows for longer ranges to be achieved than single frequency low frequency technologies, e.g. 125
kHz or 13.56 MHz. This is mainly because the tag data carrier frequency (6.8 MHz) is much higher than the power-up
frequency (125 kHz).
Applications
§ Supply Chain Management (wooden pallets, containers, crates)
§ Access control and asset control
§ Tracking of instruments
§ Tracking of mine cap lamps (possible to mount within battery enclosures)
§ Tracking of foodstuffs, in bins or bags
§ Mining tracers (ore, diamonds)
§ Electronic labelling of RF-unfriendly materials (rock samples, trees, etc)
§ Any situation where the tag needs to be embedded in, or affixed to a lossy material, even marine applications
Chipset
