RFID chip reader is an automatic identification device that can read RFID (Radio Frequentie-identificatie) tag data.
Volgens verschillende frequentiebanden, RFID chip readers are classified into low frequency RFID chip readers, high frequency RFID chip readers and ultra-high frequency RFID chip readers. The low-frequency short-range RFID chip reader has a main frequency band of 125 kHz and 134.2 kHz (animal RFID chip reader), the RFID chip readers is mainly in the 13.56 MHz band, and the passive UHF RFID chip reader is mainly 860 MHz tot 915 MHz . A passive electronic tag (RFID-kaart), also called a passive tag, receives an RF signal after entering the recognition range of the RFID chip reader, converts part of the RF energy into DC power, and then transmits the information data stored in the chip to the card reader. Passive electronic tags are low in cost, have a long service life, are small in size, and have close reading and writing distances. In bedrijf, the card reader acts as a sensor of the Internet of Things monitoring and management terminal, and recognizes different items by reading different RFID tags, and completes functions such as identification, time statistics, attendance punching and alarm prompting.
According to the shape and usage scenarios of the RFID chip readers, they can be divided into desktop RFID chip reader (https://www.rfidhy.com/RFID-products/hy-r530-RFID-reader/), hand-held RFID chip reader (https://www.rfidhy.com/rfid-products/hy-r72-uhf-handheld-reader/), wall-mounted RFID chip reader, and door-type RFID chip reader. The desktop RFID chip reader is used to directly link the computer to read and write RFID tags; the handheld RFID chip reader is used for inventory in stock; the door-type RFID chip reader is used for batch label reading and writing in the supply chain industry; the wall-mounted RFID chip reader is used for access control of attendance.
The desktop RFID chip reader is small and convenient, simple in structure, cheap in price, many used as a readers but not memory units, connected to computer equipment. Many devices are plug and play, which can be conveniently used by individuals or enterprises.The handheld RFID chip reader is widely used for stock inventory. Compared with the traditional bar-code reader, the handheld RFID chip reader achieve long-distance and non-contact reading, which greatly improves the work efficiency. The handheld RFID chip reader is more powerful compares to desktop RFID chip readers. It integrates reading, writing and storage functions. It can also integrate Bluetooth, wireless Wi-Fi, GPS and other functions. Most of the RFID chip reader used for animal management are handheld devices. They are made into specific shapes for livestock Inventory
