POS (point-of-sale) system is the location where your customer pays for the items or services that your company provides.Point-of-sale systems facilitate the completion of a business transaction between a client and a company. A point-of-sale (POS) system is a computerized network that comprises of a primary computer connected to many checkout terminals and backed by a variety of hardware features ranging from barcode scanners to card payment terminals.
Because different businesses have distinct profiles, they require diverse point-of-sale systems. Restaurants, retail shops, and grocery stores, for example, all have their own specialties, which is why they require a POS system that is tailored to their needs.
A scale at the point of sale is required at a grocery shop, and a café must be able to alter menus in the event of special deals.
However, there are two types of enterprises that require a point of sale system in general. Retailers and hospitality enterprises, such as restaurants and hotels, fall within this category. As a result, there are primarily two types of POS systems: one for retail and the other for restaurants.
History of POS (Point-of-Sale) System
Early electronic cash registers (ECRs) were limited in function and communication capacity, and were controlled by proprietary software. IBM released the IBM 3650 and 3660 retail systems in August 1973, which were essentially a mainframe computer that could operate up to 128 IBM 3653/3663 point of sale registers. This system was the first to use client-server technology, peer-to-peer connections, LAN simultaneous backup, and remote initialization in a commercial setting. It was deployed in Path mark supermarkets in New Jersey and Dillard’s department stores by the middle of 1974.
In 1974, William Brobeck and Associates designed one of the first microprocessor-controlled cash register systems for McDonald’s Restaurants.  The Intel 8008, a relatively early CPU, was used (and forerunner to the Intel 8088 processor used in the original IBM Personal Computer).
On the 16-bit Atari 520ST color computer, Eugene “Gene” Mosher launched the first graphical point-of-sale software with a touchscreen interface under the ViewTouch trademark in 1986.
 It had a color touchscreen widget-driven interface that allowed widgets to represent menu items to be configured without requiring low-level programming.
programming.  The ViewTouch point-of-sale software was initially exhibited in front of a huge crowd at the Atari Computer booth at Fall Comdex in Las Vegas, Nevada, in 1986. This was the first commercially available point-of-sale system featuring a widget-driven color graphic touchscreen interface, and it was implemented in a number of restaurants around the United States and Canada.
In 1986, IBM released the 468x POS system, which was based on Digital Research’s Concurrent DOS 286 and FlexOS 1.xx, a real-time multi-tasking multi-user operating system.
