Depending on the size of the tags and the operating power emitted by the UHF reader, UHF technology uses the radio wave frequency spectrum to enable reading distances of several metres (equal to several dozen feet). Identiv's UHF designs take advantage of our in-depth knowledge of RFID deployments, are intended to outperform competitive products, and are frequency optimised for certain environmental restrictions. For support in a number of applications, such as near field communication (NFC) with HF interfaces, we also provide dual-frequency tags (UHF+HF).
