M2101 is a new generation of high-performance UHF read-write module developed with great concentration. This module is another single-channel UHF read-write core module based on PR9200 design after the M2100 module. It has more stable performance and more powerful functions. It is specially designed for The high-performance UHF RFID read-write module designed for highly challenging RFID application environments can provide customers with unprecedented read-write performance in the industry. This module has been verified by a large number of tests and long-term uninterrupted work (180 consecutive days), and its stability and reliability can fully meet its use requirements.
