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

What is an UHF RFID reader?
The reader whose working frequency band is UHF (860MHz~960MHz) is called UHF RFID reader. It has good transmission speed and long reading distance. It can read multiple tags at one time. 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 one time.
2. Penetration identification: Items with RFID tags placed on non-metallic or non-transparent materials such as paper, wood and plastic can also be identified 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. Miniaturized tag size and diverse shapes: reading RFID tags is not limited by size and shape. In addition, RFID tags can be developed in miniaturization and various forms to be applied to different products.

Classification of UHF RFID readers:
1. Portable
The portable RFID reader is equipped with the Android operating system, with display and input functions, data storage and calculation functions, mobile operation, and convenient operation. At the same time, it integrates functional modules such as barcode scanning, WIFI, WWAN, Bluetooth, etc., 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 and can match a variety of antennas to achieve high tag reading rate and fast read and write processing. It is suitable for various applications such as warehousing and logistics, asset management, smart stores, and smart cities.
