The”point of sale” (POS), or”voucher” as it’s more commonly called, refers to the place where a trade is made. The first known point of sale program was developed by IBM in 1973 and made use of electronic cash registers (ECR). The system used relatively new technologies in the time like client-server and peered to peer communications, Local Area Networks (LAN) for simultaneous backups and remote initialisation. A year later it was designed, it was of excellent use to retail stores across America.
In 1979, another Enlite POS program was designed, this time by Gene Mosher, which he utilised in his restaurant industry. His original software ran on an Apple II computer and has been programmed to get customer orders at the restaurant’s entrance, and a copy with complete details would be printed within the kitchen. In this manner, customers received their meals at their tables considerably faster than any other restaurant. Mosher also developed the first graphical touchscreen point of sale program in 1986 with an Atari ST computer and the Neochrome bitmap graphics editor.
From the post-1990s, the development of multi-functional POS programs went hand-in-hand with the development of local processing power, local storage information, media, and the graphic user interface. Various POS programs were also developed for operating systems like Windows and Unix.
For the last two decades, retailers and sellers alike have been working on hardware interface standardisation of the growing point of sale programs, also aiming to simplify interconnection of multiple POS devices (hardware and software). Standardizations like OPOS for both Windows and JavaPOS for Java are some of the products of the initiative. OPOS, which stands for OLE (object linking and embedding) for POS, was the first globally-accepted standard and was a product of their joint efforts of Microsoft, NCR Corporation, Epson, and Fujitsu-ICL. JavaPOS was developed by Sun Microsystems, IBM, and NCR Corporation. Both of these developments aimed to produce the contemporary point of sale programs and end of sale hardware platform independent.
The unfolding of this new millennium gave way to the most innovative development of POS reseller program yet. Because of this, contemporary point of sale programs are all expected to have the rapid and consistent rate, they ought to be reliable and simple to use, with multi-functionality, remote supportability, and can be purchased at a much lower price than ever before.
Point of sale programs has come a long way since the development of electronic cash registers. Today, retailers can enjoy the benefits of the end of sale programs as a means of earning business transactions more comfortable, quicker, and free of inevitable human mistakes. First and foremost, the point of sale programs are cost-effective, and frequently produce the highest return on investment that a retail business owner could make into a technology solution.
