An RFID Ultra High Frequency (UHF) reader is a device designed to communicate with RFID tags operating at ultra high frequencies, typically at frequencies 860 MHz to 960 MHz. Here are some key points about UHF RFID readers:

 1. Read Range:

UHF RFID readers can typically read tags from several meters away, sometimes up to 10 meters or more depending on the reader's power output and the tag's design.

 2. Communication Interface:

UHF RFID reader typically support various communication interfaces such as TCP/IP、USB、BLE、WiFi、I2C、UART、Wiegand、RS-232、RS-485. These interfaces allow the reader to communicate with external devices such as computers, microcontrollers, or network servers.

 3. Communication Protocols:

UHF RFID reader support various communication protocols, including EPC C1G2 and ISO18000-6C standards. These protocols define the communication methods between the reader and the RFID tags.

 4. Features:

UHF RFID technology offers advantages such as longer read ranges, higher data transfer rates, and can read multiple tags simultaneously and at high speeds, making them efficient for applications where large volumes of items need to be tracked quickly.

 5. Applications:

These features make UHF RFID reader suitable for applications where fast and reliable identification of multiple tags is required over a large area. UHF RFID is widely used in supply chain management, inventory management, access control, asset tracking and many more.
