125KHz card mini-module is designed for reading code from 125KHz/ 134.2KHz 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.
It is compatible with ID cards of 64 bit read-only EM4100, TK4100, and EM4102 series. This module outputs original card information (Manchester code) and ascii codes which can be directly displayed on the computer. Code form: Manufacturers code + ID card number + parity bits. It can be directly connected to Pin 2 of the computer serial port (COM). Antenna and the module has been adjusted to the best condition, with long reader distance. With CBB capacitors, it has anti-interference to temperature change.
