Description The EM4100 125Khz RFID Card Read Module is a compact and easy-to-use device designed to read RFID (Radio Frequency Identification) cards that operate at a frequency of 125Khz. It is commonly used in access control systems, time attendance systems, and other applications that require a simple and reliable means of identifying and tracking individuals or objects. The module is comprised of an antenna and a small circuit board that houses the necessary components for reading and decoding RFID signals. The antenna is designed to detect the electromagnetic signals emitted by RFID cards, and the circuit board contains a microcontroller and other electronic components that process these signals and output the relevant data. The module is typically connected to a microcontroller or other computing device via a serial interface, and it can be configured to output data in a variety of formats, including Wiegand, RS232, and TTL. This makes it compatible with a wide range of devices and systems, and it can be easily integrated into existing hardware and software environments.
