What is point of sale(POS)

The point of sale(POS) is the time and place where a retail transaction is completed. It is the point at which a customer makes a payment to the merchant in exchange for goods or after provision of a service. At the point of sale, the merchant would prepare aninvoice for the customer (which may be a cash register printout) or otherwise calculate the amount owed by the customer and provide options for the customer to make payment. After receiving payment, the merchant will also normally issue a receiptfor the transaction, though increasingly a receipt is being dispensed with.

The POS in various retail situations would use customized hardware and software tailored to their particular requirements. Retailers may utilize weighing scales, scanners, electronic and manual cash registers, EFTPOS terminals, touch screens and a variety of other hardware and software available. For example, a grocery or candy store may usea scale at the point of sale, while a bar and restaurant may use software to customize the item or service sold when a customer has a meal or drink request.

The point of sale is often referred to as the point of service because it is not just a point of sale but also a point of return or customer order. Additionally, today POS software may include additional features to cater for different functionality, such as inventory management,CRM, financials, warehousing, etc.


What is OPOS

OPOS (OLE for POS) was the first commonly adopted standard and was created by Microsoft, NCR Corporation, Epson and Fujitsu-ICL. OPOS is a COM-based interface compatible with all COM-enabled programming languages for Microsoft Windows. OPOS was first released in 1996.Java POS was developed by Sun Micro systems, IBM, and NCR Corporation in 1997 and first released in 1999. Java POS is for Java what OPOS is for Windows, and thus largely platform independent.

There are several communication ways POS systems use to control peripherals such as:

Logic Controls

Epson Esc/POS

UTC Standard

UTC Enhanced

AEDEX

ICD 2002

Ultimate

CD 5220

DSP-800

ADM 787/788

HP

There are also nearly as many proprietary protocols as there are companies making POS peripherals. Most POS peripherals,such as displays and printers, support several of these command protocols in order to work with many different brands of POS terminals and computers.
