The operating temperature of the capacitive touch screen cash register is generally between -5 ° C and 60 ° C, so the cash register is susceptible to it in the north. Instead, it uses a contact sensor to cause an induced voltage on the conductor on the screen to generate a relative current, and the touch point is measured by the distance. Therefore, in a low temperature environment, the surface of the palm skin has a low water vapor content and poor conductivity, which affects the performance of the sensor, causing it to fail to recognize the touch position and cause the touch to fail.
