Cash and Credit RegistersElectronic Cash Registers and Point-of-Sale Terminals
Some of these devices simply combined a printing electronic calculator with a cash drawer. More elaborate registers not only tracked accumulated receipts, like a traditional cash register, but handled credit card transactions and allowed clerks to scan merchandise to read off prices. These, in turn, served as input for computer systems.

- On 26 June 1974, the first installation of supermarket scanners entered service in a Marsh supermarket in Troy, Ohio. This Spectra Physics model A price scanner, is one of those first ten scanners. A package of Wrigley's chewing gum became the first purchase made with scanners that could read the new Uniform Product Code (UPC or barcode). Mounted within the unit a helium-neon laser projected a beam onto a rotating mirror and thence up through a glass plate on the top surface. The light reflected from the code label on the package and was detected by a photo-diode. A computerized cash register matched the signal from the photo-diode with information in a stored database to determine which product was being scanned.
- Spectra Physics and NCR jointly developed the system, and provided the laser scanner and the computerized cash register, respectively. A group called the "Ad Hoc Committee of the Grocery Industry" developed the barcode itself. Organized in 1970 by the consulting firm McKinsey & Co., the Ad Hoc Committee consisted of senior executives of leading firms in the grocery industry. The coding system they devised had an enormous impact on a wide range of applications, most notably for retail sales and inventory control.
