Point-of-sale (POS) PCs are an integral piece of any POS system. The system you decide to set up can do a great deal to enhance the customer experience. Systems range from a basic all-in-one single monitor, to mobile bluetooth systems, to multi-monitor systems with customer-facing rear displays.
If you aren't sure what system to get, give the Total Barcode sales team a call and they'll find out what type of system you want to set up, and which product(s) will work to help you achieve your goals. Keep in mind the operating system (O/S) you use, or want to use in your business. Some PC systems come with an O/S pre-installed, and others will be blank slates that you can install whichever O/S you want.
