Touch-based POS systems are highly advanced to enable your employees to ring up sales with touch screen. It consists of a keyboard, mouse, and POS software to make checkout more efficient, faster and accurate.
POS touch system usually has the same components that you can find in standard restaurant or retail POS. The addition of touch screen is the main difference here.
What are the main components of Touch POS?
Usually, touch POS systems consist of all the components in standard restaurant or retail POS. The addition of the touch screen is the key difference here. Touch POS consists of a PC with a scanner, POS software, and mouse/keyboard, a cash drawer, a receipt printer, and display to conduct transactions.
How does POS Touch Screen Work?
POS touch screen uses different techniques and capacitive touch screen is the most popular approach. It consists of a metallic, thin, and transparent layer which updates and records the screen on the basis of change in the flow of electric current caused by human skin. Some touch screens also use piezoelectric effect. It is a relatively new technology in which voltage is generated by touching the screen. In the end, sensor arrays detect fingers in infrared-based approach, when it gets close to or move across the screen. In all methods, the system sends signals with the movements of the mouse.
Some of the major benefits of the POS touch screen are ease of use, speed, and accuracy. In comparison to standard POS, these systems are a lot easier and faster. You don’t have to type the sale price or barcode of the item. So, it reduces human errors while improving speed.
Choosing the Right POS Touch Screen Technology
A touch screen is generally made of two glass sheets with some spacers or fillers between these layers. Screens are made of various fillers and materials like resistive, capacitive, infrared and surface acoustic waves.
The resistive touch screen is the most common POS touch screen technology and it was developed over 10 years after the development of capacitive technology. It is made with a stiff bottom layer and top layer made of glass. The POS touch screen works on pressure of your stylus, pen, finger, or anything to physically interact with the screen. Pressure comes in between the current and signals the system to work on the area where it is touched.
You can easily use a resistive touch screen wearing gloves in cold conditions or when health regulations or workplace safety is the prime concern. However, resistive screens don’t support sharp objects as they can damage the external surface.
Capacitive Touch Screen
It was creative in the 1960s and it was the first touch screen display technology. It uses your ability to work as an electric conductor. One glass panel has conductive material within. When the screen is touched, the electrical field is disrupted and a lot of processors signal the system about what system has to do next.
Surface Acoustic Wave or SAW
These displays don’t have any conductive coating or metal. They have ultrasonic waves reflected by reflectors and transducers. When you touch the glass, it absorbs a part of the wave and detects touch. This POS technology offers great clarity and is also very sensitive to impurities and costly. Any oil or dirt can slow down the response time.
This technology has been very popular among larger devices. A grid of LED beams is used in vertical and horizontal patterns for enhanced accuracy. It is known to have a very durable screen compared to a capacitive screen. It doesn’t need any conductive coating or surface. Keep in mind that dust and dirt can affect the functionality of the device.
