UHF RFID offers important benefits for users planning to implement RFID systems in performance and read range. Although generally more costly and often larger than their LF (low frequency) and HF (high frequency) counterparts, versions of UHF tags can be read from distance of as much as 30 meters and in ways that allow hundreds of tags to be read in less than a second. UHF RFID readers are also generally more expensive than LF and HF ones but costs are dropping all the time.
Another important feature of UHF RFID is the presence of the EPC Global GEN2 standard, which defines the way in which tags and readers interact. The widespread adoption of this standard is helping to reduce prices and promote inter-operability, allowing multi-enterprise and multi-national systems to become feasible.
UHF tags are also available in a wide range of formats for mounting on different materials.
