EM18 RFID Reader module is one of the commonly used module for Radio Frequency Identification Projects. EM18 RFID Reader Module can be directly interfaced with a microcontroller using UART communication and with a PC using a RS232 converter. EM18 RFID Reader Module can work with any 125KHz RFID tags and it can provide UART / Wiegand26 output formats. Pitch of output pins are 2.54mm, thus it can be directly inserted to a breadboard for project developing.
The EM-18 RFID Reader module generates and radiates RF Carrier Signals of frequency 125KHz through its coils. When a 125KHz Passive RFID Tag (have no battery) is brought in to this field, will get energized from it. These RFID Tags are usually made using a CMOS IC EM4102. It gets enough power and master clock for its operations from the electromagnetic fields produced by RFID Reader
