When designing the layout of your point of sale system, people often wonder “what is the best way to set this up”. Do I put the cash drawer on the counter? Do I put the monitor on the drawer? Do I put the printer on the drawer? Where does the keyboard go? Do I need a mouse?
The good thing about an All-In-One PC is that you don’t have to hide a computer tower somewhere where it might get kicked or spilled on, the PC is in the monitor. The bad thing about this is all the cables are sticking out of the PC. However if you bought a quality made for point of sale touch computer then the base can often times conceal the cables. Usually the metal bases are hollow with a hole at the top and bottom where cords can run from under the counter, straight into the base, and into the computer. All your USB Cables, the power cable, the printer cable etc. all nicely tucked away. If your running the cables in the counter then chances are your not going to want to put the PC on top of the cash drawer. Instead you can buy under-counter mounting brackets and attach the cash drawer stealthily under your counter.
If you want the PC on top of the cash drawer, then the cables can still run into the base but instead of going into the counter you can run them straight to the peripheral and then wire tie the excess cable inside the base of the PC.
One other option that typically doesn’t work for a retail cashier but does work for restaurants is to wall mount the all in one PC with a VESA bracket. You can use a standard VESA mount that you would get for home theater use, but don’t skimp as a cheaper bracket may wobble or fall off the wall, you want one that was designed for touch screen use.
