Restaurant POS refers to point of sale (POS) software that runs on computers, usually touch screen terminals or wireless handheld devices. Restaurant POS systems assist businesses to track transactions in real time.

Typical restaurant epos system software is able to print guest checks, print orders to kitchens and bars for preparation, process credit cards and other payment cards, and run reports. In addition, some systems implement wireless pagers and electronic signature capture devices.

In the fast food industry, an epos system  may be at the front counter, or configured for drive through or walk through cashiering and order taking. Front counter epos systems take and serve orders at the same terminal, while drive through registers allow orders to be taken at one or more drive through windows, to be cashiered and served at another. In addition to registers, drive through and kitchen monitors may be used by store personnel to view orders. Once orders appear they may be deleted or recalled by "bump bars", small boxes which have different buttons for different uses. Drive through systems are often enhanced by the use of drive through wireless (or headset) systems which enable communications with drive through speakers.

Epos systems are often designed for a variety of clients, and can be programmed by the end users to suit their needs. Some large clients write their own specifications for vendors to implement. In some cases, Epos systems are sold and supported by third party distributors, while in other cases they are sold and supported directly by the vendor.

Wireless systems consist of drive though microphones and speakers (often one speaker will serve both purposes), which are wired to a "base station" or "centre module." This will, in turn broadcast to headsets. Headsets may be an all-in-one headset or one connected to a belt pack.

Hospitality point of sales systems are computerized systems incorporating registers, computers and peripheral equipment, usually on a computer network. Like other point of sale systems, these systems keep track of sales, labour and payroll, and can generate records used in accounting and book keeping. They may be accessed remotely by restaurant corporate offices, trouble shooters and other authorized parties.

Point of sales systems have revolutionized the restaurant industry, particularly in the fast food sector. In the most recent technologies, registers are computers, sometimes with touch screens. The registers connect to a server, often referred to as a "store controller" or a "central control unit." Printers and monitors are also found on the network. Additionally, remote servers can connect to store networks and monitor sales and other store data.

The efficiency of such systems have decreased service times and increased efficiency of orders.

Another innovation in technology for the restaurant industry is Wireless POS. Many restaurants with high volume use wireless handheld POS to collect orders which are sent to a server. The server sends required information to the kitchen in real time.
