Ming Wah URF-35/KRF-35 series IC card reader demo program to change density

Equipment Features
RF series of non-contact type IC card reader in Shenzhen Ming Wah's developed non-contact card reader device, which consists of the host, antenna, serial interface, etc., through the RS232 serial interface to achieve the same PC-connection. Random provides a user interface function library can meet the needs of secondary development; its perfect, reliable interface functions to support access to the full functionality of radio frequency card. At present the device has been widely used in access control, attendance, and highways, petrol stations, car parks, public transportation and other fees and charges system.
