Point Of Sale Computer System

The term point of sale is used to describe a variety of things. It may be the case in a store or a place where transactions occur. Most often, the term refers to a cash register. The abbreviation commonly used for point of sale POS. Each letter of the abbreviation is pronounced separately (eg POS) compared to pronounce the acronym itself (legs, for instance).

When computers were first invented, large retailers have been the first to implement the POS system to help automate many tasks of operating a retail store. These computers were very large and expensive. This has limited the adoption of POS systems to major retailers such as grocery chains. The introduction of low-cost personal computers in the 1980s led to retail stores of all sizes to improve efficiency with the help of POS systems.

A common point of sale system includes a computer, cash drawer, receipt printer, pole display, barcode scanner, card reader magnetic swipe, a modem and a point of sale software. Each room offers the following features:

• Personal Computer - Operations POS software and provides hardware interface for devices such as printers, card readers, credit and so on.


• Till - A lock box that stores cash and is triggered to open the cash register software.


• Receipt Printer - Prints a hard copy of the sales transaction for the customer.


• Pole Display - LED display facing the customer and shows each item and price scanning.


• Bar Code Scanner - A type of laser device (gun style, free style) when he tripped on a bar code, lines of bar code converted to numbers. This number or SKU (Stock Keeping Unit) is then transmitted to the POS computer to automatically search for prices.


• Magnetic Swipe Reader - Reads the magnetic strip on the back of a credit card or debit card. The information stored on magnetic tape includes credit card number, expiration date, customer name, and address. The information is transmitted to a network processing credit card through the POS system of payment of the goods.


• Modem - Allows the sale of computer point of contact centers, processing credit card and other parts of the chain.


• Point of Sale - Software that runs on the computer, the various control devices, and performs the traditional functions of the cash register sounds like a sale.

Today, in point of sales software contains many more features in addition to the cash register. Therefore, the term POS system is gradually replaced by the phrase Retail Management System. POS is now commonly referred to as only the function of a cash register system, retail management.

When systems of outlets have been introduced, their only function was to ring the sales department codes. This automation has allowed retailers to see their simple daily sales summary by department. The automation has saved many hours a retailer in determining the departments contained the most popular items and how many dollars of sales were generated. Once the computers were put in place, the rapid evolution of today's sophisticated retail management began.

The next step in the evolution of point of sale has been the addition of an automatic pricing. Rather than enter a department code and then the price of an item, cashiers can now enter the SKU (Stocking Keeping Unit) of the question and T.
