(Ultra-High Frequency) UHF RFID CARDS
The UHF frequency band covers the range from 300 MHz to 3 GHz, most passive UHF systems comply with the UHF Gen2 standard and use the 860 to 960 MHz band. The UHF frequency band is regulated by a single global standard called the ECP global Gen2 (ISO 18000-63) UHF standard.
The read range of passive UHF systems can be as long as 12 m, and UHF RFID has a faster data transfer rate than LF or HF. UHF RFID is the most sensitive to interference, but many UHF product manufacturers have found ways of designing tags, antennas, and readers to keep performance high even in difficult environments. Passive UHF tags are easier and cheaper to manufacture than LF and HF tags.
