RFID radio frequency identification is a non-contact automatic identification technology. It can identify specific targets and read and write related data through radio signals, without the need to establish mechanical or optical contact between the recognition system and specific targets. The recognition process does not require human intervention and can work in many harsh environments. It can identify moving objects and can identify multiple tags at the same time. The working frequency band of RFID is divided into: low frequency (LH), high frequency (HF), ultra high frequency (UHF).

What is an UHF RFID reader?
The reader with the working frequency band of UHF (860MHz~960MHz) is called UHF RFID reader. It has good transmission speed and long reading distance. It can read multiple tags at once. It is mainly used in logistics and supply chain management. , Production line management, aviation, smart shelves, unmanned retail cabinets and other fields.

Features of UHF RFID Reader
1. Multi-tag reading: UHF RFID reader can read multiple electronic tags at once.
2. Penetration recognition: The items pasted with RFID tags on non-metallic or non-transparent materials such as paper, wood and plastic can also be recognized by UHF RFID readers.
3. Tag storage data capacity: Compared with barcodes, RFID tags have large storage capacity and can store information describing items in detail.
4. Tag volume miniaturization and diversified shapes: Reading RFID tags is not limited by size and shape. In addition, RFID tags can be miniaturized and developed in various forms to be applied to different products.

Classification of UHF RFID readers
1. Handheld
The handheld RFID reader is equipped with an Android operating system, with display and input functions, data storage and calculation functions, mobile operations, and convenient operation. At the same time, it integrates barcode scanning, WIFI, WWAN, Bluetooth and other functional modules, which can be used in clothing retail, power inspection, warehouse management, asset management and other fields.

2. Fixed
The fixed RFID reader integrates a variety of protocol interfaces, which can be matched with a variety of antennas to achieve high reading rate and fast read and write processing of tags. It is suitable for a variety of applications such as warehousing logistics, asset management, smart stores, smart cities, etc.
