1. Introduction to UHF RFID Technology |
UHF RFID (Ultra High Frequency Radio Frequency Identification) is a technology used for automatic identification and data capture. It operates within the UHF frequency range of 860 to 960 MHz. UHF RFID systems consist of three main components: tags, readers, and antennas. UHF RFID tags contain a microchip and an antenna, while readers emit radio waves and receive signals from the tags. The primary advantage of UHF RFID over other types of RFID technology, such as LF (Low Frequency) and HF (High Frequency), is its ability to read tags at longer distances and faster speeds. |
