Jinfeng Digital APC Series Infrared single touch pos machine, is a touch pos machine OASIS 2015 listed, he has high integration, low power consumption, with flexibility, it features a variety of forms. Mature and stable machine performance, rich I / O expansion interface, created in the business field of information technology a good touch experience, improve customer satisfaction. Infrared touch screen introduces infrared touch screen technology (Infrared Touch Screen Technology) launched by mounted on the touch screen frame of infrared and receiving the sensing elements on the screen surface to form an infrared detection network, any touch object can change the infrared on the contacts and implement a touch screen operation. The principle of infrared touch screen is similar to the surface acoustic wave touch, it uses an infrared transmitter and receiver sensing element sense. These elements are formed on the surface of the screen infrared detection network, touch operation of the object (such as a finger) can be changed infrared electric shock, which was subsequently converted into a coordinate position achieved touch response operations. On the infrared touch screen, circuit board device arrangement of the four sides of the screen with infrared emission control and infrared receiver, the corresponding form if they had cross-infrared matrix.
