RFID2 is a radio frequency identification unit. Built-in WS1850S chip, working frequency is 13.56MHz. Supports reading card, writing card, recognition, recording, and encoding RF card Multiple functions such as authorization and authorization. Use magnetic field induction technology to realize non-contact two-way information interaction, read and verify the information of proximity cards. It can be used in access control systems, check-in systems, warehouse goods entry and storage, and community vehicle entry and exit registration needs Application scenarios for information verification. RFID2 compared to the previous generation RFID UNIT only makes the replacement of read and write IC (RC522->WS1850S), there is no difference in function.
