Cash Register

A cash register is a mechanical or electronic device used in department stores and retail businesses to calculate and record sales transactions, hold banknotes and coins in a secure drawer, and print receipts for customers.

James J. Ritty, owner of a tavern in Dayton, Ohio, patented the cash register on November 4, 1879, as he’d grown tired of his staff stealing his money.

Ritty was inspired to invent the machine while travelling to Europe on a steamboat in 1878, after visiting the engine room and noticing a mechanical device that tracked the revolutions of the ship’s propeller.

The first registers were entirely mechanical, without receipts. The employee was required to ring up every transaction on the register, and when the total key was pushed, the drawer opened and a bell would ring, alerting the manager to a sale taking place.

Dubbed "Ritty's Incorruptible Cashier," his original 1879 patent did not feature a cash drawer at all; it functioned as a mechanical counter with a clock-like dial that displayed running sales totals.

John H. Patterson of the National Cash Register Company improved the cash register by adding a paper roll to record sales transactions, thereby creating the receipt.

During the late 19th and early 20th centuries, registers were often housed in elaborate, decorative brass, bronze, or cast-iron cases, leading NCR to run the world's largest brass foundry.

In 1906, inventor Charles F. Kettering designed the first cash register powered by electricity while working at NCR, creating a small motor that ran in brief bursts so clerks no longer needed to turn a hand crank.

The retail convention of pricing items at .99 or .95 cents was widely adopted to force the shop clerk to ring up the sale and open the till to hand back a coin in change, keeping cashiers honest.

The first commercial item ever scanned with a bar code at a retail checkout was a 10-pack of Wrigley's Juicy Fruit chewing gum, scanned on an NCR register at a Marsh supermarket in Troy, Ohio, on June 26, 1974.

Cashback at the till was introduced in the United Kingdom in 1990 by Tesco, allowing shoppers to withdraw cash while paying and reducing the fees supermarkets paid to deposit excess notes at the bank.

Cash register receipts are printed on thermal paper coated with chemical additives known as obesogens (such as bisphenol A and bisphenol S), which can be absorbed through the skin and disrupt metabolic hormones linked to gaining fat.
