U2 UHF read  module is a UHF chip independently developed by Fonghua Technology, which is embedded in various large devices for reading and writing. .This product adopts an innovative dual communication design of USB and serial port, and the interface adopts drive free plug and play technology, which can independently control the required communication methods. It is equipped with a 3dbi ceramic antenna, with a reading distance of 0-2 meters (related to the label) and a writing distance of 0-50 centimeters. It provides comprehensive secondary development SDK documentation and after-sales technical support. Mainstream protocols for users to quickly use include EPCglobal UHF class 1 Gen 2/ISO 18000-6C, as well as national standard GB/T 29768-2013 chip cards or

A card reader customized for special applications in the field of tags that supports non-contact chip cards and supports multi tag group reading recognition. It can recognize from a distance and adjust the distance within the recognition range, making it convenient for users to customize and use.

Note: The RF card reader block is sensitive to the environment, and metal has a reflection and shielding effect on electromagnetic waves. That is, metal has an impact on both the card reader and the tag. If there is metal nearby, it will reduce the reading rate of the tag. So when installing the equipment, try to stay away from metal objects and other electronic coils and other objects as much as possible. In addition, objects containing water such as liquids and wood have a significant impact on UHF products.
