This low cost RFID module is perfect for connecting to an Arduino. It connects via a 9600 bps UART serial connection and outputs the tag number when an EM4100 compatible RFID card comes near. Perfect for access control projects. RDM 6300 125 KHz card reader mini-module (HCRFID0006) is designed for reading code from 125KHz (ID) compatible read-only tags and read/write cards. It can be applied in office/home security, personal identification, access control, anti-forgery, interactive toy and production control systems etc. The reader will output id code of any compatible tag placed with within range via its serial UART interface. The reader requires no software interaction and can be interfaced directly to a microcontroller or to a PC via a serial port interface such as a USB to serial adaptor.Includes external antennaMaximum effective distance approx 5 cm.Less than 100ms decoding time9600 Baud UART interface (5 Volt TTL RS232)Support EM4100 compatible read only or read/write tagsSmall outline design (3.85cm x 1.9cm)Support external antennaMaximum effective distance up to 150mm*Support EM4100 compatible read only or read/write tags (125KHz ID)Small outline design*Please note range is also dependant on sensitivity of tags used.
