M5Stack Mini RFID Reader/Writer 2 Unit WS1850S 13.56MHz Frequency compatible with Access Control Systems Check-in Systems SD

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 incompatible withmation interaction. read and verify the incompatible withmation 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 compatible with incompatible withmation 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.Product features1.
