850-960Mhz Ultra High Frequency Cards (ISO18000-6,EPC Gen2)
UHF follows the EPCglobal Gen2 standard and uses the 850—960Mhz frequency band to provide fast data transfer rates and much longer read ranges (up to 10m) compared to either LF or HF cards. UHF labels and tags are used extensively in warehousing and goods tracking while UHF cards are popular for location and attendance tracking applications. UHF is negatively affected by materials in the environment such as metals and liquids, but is the best choice for applications that require a long read range and simultaneous reading of a large number of tags. Common UHF chips offered by OPRFID include:
Alien Higgs 3: EPC Class1 Gen2 chip with 96—480bit EPC memory, 512bit user memory and 64bit UTID with memory read protection.
Alien Higgs 4: EPC Class1 Gen2 chip with 128bit EPC memory, 128bit user memory and 64bit UTID with memory read protection and pre-encoded with unalterable enterprise-wide serialization scheme.
NXP UCODE 7: EPC Class1 Gen2 chip with 128bit EPC memory and 96bit UTID.
NXP UCODE 7m: EPC Class1 Gen2 chip with 128bit EPC memory, 32bit user memory and 96bit UTID.
