Most touch screen cash registers use either the resistive or capacitive touch screen technology. Both are the most common touch screen technologies and each offers different pros and cons. A capacitive touch screen register requires the user to use their fingers or a specially charged stylus. This is common since these cash registers are often used in bars and restaurants where the lighting might be low and a traditional cash register keypad isn’t illuminated like a screen is. A capacitive screen minimizes the chances of an error from other objects that might bump the screen since it needs a conductive material such as the human finger to release the charge which is recognized as a touch. The resistive is used where costs are a consideration and the screen needs to be able to stand up to tougher conditions.
