Touch-screen technology is everywhere in point of sale software now as today touchscreens are pretty comparable in price.
Here are three significant advantages to using touch.
1) They are easier to use; it is more natural to press buttons highlighted on the computer. Plus it is also much easier to use as your eyes do not have to keep looking away from the screen to the keyboard.
2) It is faster according to some studies I have seen. They report it is 20% faster. That is why most corporate and large clients of ours always use touch as most people today are not a touch typist.
3) You do not need such a big desk. Non-touch screens to work need a mini desk as a keyboard and mouse need to be handy to work.
Our POS system is built for touch, so you may want to give it a try.
