125Khz RFID module RDM6300 - UART

RDM6300 125KHz cardreader mini-module is designed for reading code from 125KHz card compatible read-only tags and read/ write card. It can be applied in office/ home security, personal identification, access control, anti-forgery, interactive toy and production control systems etc. * RDM6300 is the update version of RDM630, it has higher sensitivity and longer read range. The pins and output data is 100% compatible with old RDM630 module. FEATURES : Support external antenna Maximum effective distance up to 50mm Less than 100ms decoding time Uart interface Support EM4100 compatible read only or read/ write tags Built-in external bi-color LED and buzzer driver Small outline design Datasheet here Note: Module will notify whenever 125khz tag approaches, tag serial number will be send via IO pin and save UART port for MCU. Either interupt or polling mode is OK to read the ID.
