UM021 UHF module is our research and development of a new generation of UHF RFID series products with the module, this module American Standard module, does not distinguish between frequency bands. The module uses high-performance multi-tag recognition algorithms to provide ultra-high recognition rate; optimized algorithms designed specifically for the application of reading a small number of tags, to improve the tag response speed; low-voltage, low-power design, to ensure operational efficiency while reducing power consumption.
The product will read the card part of the module integration design, so that the product in the parking lot to meet the technical requirements at the same time, has a stable reading performance, good consistency of reading performance, low operating current and temperature, long service life, reading performance by the outside world has little impact, ultra-low power consumption design, significantly reduce energy consumption, high operating efficiency, development interface is simple, etc. Advantages.
