The composition, types and application scenarios of UHF readers
UHF RFID reader (abbreviation of Radio Frequency Identification), also known as "RFID reader", is wireless radio frequency identification. It automatically identifies target objects and obtains relevant data through radio frequency identification signals without manual intervention. It can identify high-speed moving objects and simultaneously Identify multiple RFID tags and operate quickly and conveniently.
It can not only read radio frequency tags, but also erase and write data, so it is called a reader/writer. If it can only be read and cannot be erased, it is called a card reader or radio frequency identification device. Readers and writers are widely used and are mainly used in identity recognition, cargo identification, security authentication and data collection. They have the characteristics of safety, accuracy, speed, expansion and strong compatibility.
A typical reader/writer terminal generally consists of three parts: an antenna, a radio frequency interface module and a logic control module.
RFID readers are divided into radio frequency frequencies: low-frequency readers, high-frequency readers, ultra-high-frequency readers, dual-frequency readers, 433MHz active readers, microwave active readers, etc., but they are more common. The main applications are UHF readers and writers, so now enter the wonderful world of UHF readers and writers with Little New!
First, let's take a look at the categories of UHF RFID readers:
It is understood that the most common ones on the market include: desktop card issuers, all-in-one fixed readers, and USB interface readers and writers.
The main function of this type of reader is card issuance and initialization of RFID tag data. It can perform card reading, card writing, authorization, formatting and other operations on tags. It is suitable for RFID card issuance in various fields such as warehousing, logistics, clothing, and production line management. use. Its characteristics: small size, low cost and short reading distance.
2. Integrated fixed readers
The biggest feature of this type of reader is that the RFID reading and writing module is integrated with the antenna. It has strong anti-interference ability, excellent protection performance, easy installation and use, and high cost performance. It is mainly used in license plate anti-counterfeiting recognition management, smart parking lot management, Warehouse material entry and exit supervision and identification management, airport luggage and package identification management, intelligent manufacturing and other fields.
Connect to portable front-end data collection devices such as smartphones, PDAs, laptops, printers, and handheld terminals through USB interfaces.
