EM-18 RFID Reader Module
EM-18 RFID Reader is one of the commonly used module for Radio Frequency Identification Projects. It can be directly interfaced with a microcontrollor using UART communication and with a PC using a RS232 converter. This 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.
RFID Tag Key Fob – 125KHz
This RFID tag comes in a key chain package, which is commonly used in Access Control, Presence Sensing etc. This RFID tag operates in 125KHz RF range and have a 32 bit unique ID which is not re-programmable. It doesn’t require any power supply or battery. It takes power and clock for its operation from the electromagnetic field produced by the RFID Reader using an internal coil.
