While the POS system has many parts that are all crucial, the one that you will interact with the most is the touch screen. It allows the user to input information via the display rather than using a keyboard and mouse, resulting in more efficient customer interactions. Depending on your business, one touch screen option may be better than the others, so it is important to understand your choices before you make a decision.
5-Wire Resistive:
For years, this has been the primary screen technology used in POS systems. This screen uses two layers that are separated by a narrow gap. When pressure is applied, electrical flow is detected and the computer recognizes it. While this screen has low image clarity and can be scratched, there are a number of advantages:
- The user can utilize practically any object on the screen, including:
--Finger
--Stylus
--Pen
--Edge of credit card
- Low cost
- Low power consumption
- Resists liquids, dust and other containments
Projected Capacitive:
In recent years, there have been amazing advancements in the use of touch screens. Smartphones and tablets would not be the devices they are without screens that were accurate and provided high image clarity. Projected capacitive screens are made of glass with embedded films that allow for the computer to sense the changes in electrical currents that occur when a finger touches the screen. While cost is higher and the user must use their finger as the input object, there are advantages to using this screen type:
- Excellent image clarity
- More resistant to scratching than other touch screens
- Improved aesthetics
- Multi-touch that allows software to work in new ways
Understanding the options in touch screen technology when selecting a POS system is very important to the overall performance and efficiency that will be realized. The latest technology is not always the best for your specific needs, so really consider how your employees will be interacting with the POS terminals prior to making a decision. Let the use of the terminal be the main factor when making the final decision. Making the right decision the first time is the ultimate goal when selection the right touch screen for your company.
