Does the cash register choose a good resistance screen or a capacitive screen?

What is the resistive screen and capacitive screen? I believe that many customers do not know, only know that the screen of the cash register is only touched, but did not expect to touch. Use a mobile phone to give a simple example to distinguish between the two touch methods.

(1) The resistive screen will carry a stylus. This is because its operation is done by “dot”. If there is no stylus, we can use the nail to operate the screen. Representative phones for this type of screen are the Nokia 5800, N97 and earlier Microsoft Windows Mobile phones.

(2) The capacitive screen is operated by touching the “face” of the screen with the finger, so the sensitivity is better than the resistive screen and multi-touch is also supported. Its representative models are Nokia X6, N8, Apple iPhone and most mid- to high-end Android phones and Windows Phone phones.

Knowing the difference between resistors and capacitors, how do we choose when we buy a cash register? From the mainstream cash register touch method, most of the cash register manufacturers in the market default to the use of resistive touch, the cost is lower than the capacitive screen, but the environment is better than the capacitive screen. The resistive screen has almost no requirements for the external environment, and can work under any conditions. The capacitive screen is relatively "squeaky" and has strict limits on voltage, temperature and humidity.

What is the advantage of the capacitive screen? Capacitive screens are made of single-layer thickened tempered glass, which has high hardness, durability and long service life. Its touch is sensitive and supports multi-touch.

Both resistance and capacitance touch methods have their advantages and disadvantages. As for whether the cash register to be purchased is good with a capacitive screen or a resistive screen, you still have to make your own choice.
