What Does POS Stand For? If you are a merchant, you have probably come across the term POS before. What is POS, and how does it help your business? POS stands for "Point of Sale." This is the system that your business uses to take money from your customer and provide them with a receipt. Almost all POS systems are computerized for accuracy and convenience. Essential Parts of a POS System If you are in the market for a new POS system, you need to know what the basic parts are. Keep in mind that you can buy your POS system as a bundle, with software included, or you can put together your own system by buying the parts separately. POS Computer - The computer is the most important part of the system. Some POS computers are like PCs that run POS software that you load onto them. Others come with a software program and do not operate like a regular computer.

It is connected to the POS computer and will only open when the computer sends it the proper signal. This helps protect you from theft. POS Monitor - The monitor allows you to see what you are inputting into the POS computer. Many POS monitors are touch-screen enabled, which allows them to be the input device, eliminating the need for a keyboard. Scanner - The scanner allows you to scan the barcode on the merchandise you are selling. Some scanners are hand held, while others are imbedded into the POS device. The scanner is technically an optional item, since UPC codes can be entered by hand, but using a POS system efficiently without one is almost impossible. Receipt Printer - The receipt printer is connected to the POS system to allow you to quickly print off a receipt for your customer. In many systems the receipt printer also prints the receipt that the customer signs when paying via credit card.
