The UHF frequency band covers the range from 300 MHz to 3 GHz. Systems complying with the UHF Gen2 standard for RFID use the 860 to 960 MHz band. While there is some variance in frequency from region to region, UHF Gen2 RFID systems in most countries operate between 900 and 915 MHz.
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.
UHF RFID is used in a wide variety of applications, ranging from retail inventory management, to pharmaceutical anti-counterfeiting, to wireless device configuration. The bulk of new RFID projects are using UHF opposed to LF or HF, making UHF the fastest growing segment of the RFID market.
The UHF frequency band is regulated by a single global standard called the ECPglobal Gen2 (ISO 18000-6C) UHF standard.
DSS also offers Enhanced Tribal Cards working directly with tribes and DHS/CBP. This is not a traditional reseller or dealer sale due to the secure nature of the cards. The ETC cards are land and sea passports for bordering countries and part of the Western Hemisphere Travel Initiative. Again, these secure cards are issued to U.S. or Canadian citizens who are members of a “U.S. Federally Recognized Tribe,” as an alternative travel document to a U.S. Passport. The ETC could be used by tribal members to cross U.S. land or sea borders. For more info please visit http://enhancedtribalcard.com/
