History

An early mechanical cash register was invented by
James Ritty James Jacob Ritty (29 October 1836 – 29 March 1918), saloonkeeper and inventor, opened his first saloon in Dayton, Ohio in 1871, billing himself as a "Dealer in Pure Whiskies, Fine Wines, and Cigars." Some of Ritty's employees would take ...

With the help of James' brother John Ritty, they patented it in 1883. It was called ''Ritty's Incorruptible Cashier'' and it was invented to stop cashiers from pilfering and eliminate employee theft and

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. Those original machines were nothing but simple adding machines. Since the registration is done with the process of returning change, according to

for external bookkeeping purposes. The original purpose of the receipt was enhanced fraud protection. The business owner could read the receipts to ensure that cashiers charged customers the correct amount for each transaction and did not embezzle the cash drawer. It also prevents a customer from defrauding the business by falsely claiming receipt of a lesser amount of change or a transaction that never happened in the first place.

Cash drawer

Cash registers include a key labeled "No Sale", abbreviated "NS" on many modern electronic cash registers. Its function is to open the drawer, printing a receipt stating "No Sale" and recording in the register log that the register was opened. Some cash registers require a numeric password or physical key to be used when attempting to open the till. A cash register's drawer can only be opened by an instruction from the cash register except when using special keys, generally held by the owner and some employees (e.g. manager). This reduces the amount of contact most employees have with cash and other valuables. It also reduces risks of an employee taking money from the drawer without a record and the owner's consent, such as when a customer does not expressly ask for a receipt but still has to be given change (cash is more easily checked against recorded sales than

). A cash drawer is usually a compartment underneath a cash register in which the cash from transactions is kept. The drawer typically contains a removable till. The till is usually a plastic or wooden tray divided into compartments used to store each denomination of bank notes and coins separately in order to make counting easier. The removable till allows money to be removed from the sales floor to a more secure location for counting and creating bank deposits. Some modern cash drawers are individual units separate from the rest of the cash register. A cash drawer is usually of strong construction and may be integral with the register or a separate piece that the register sits atop. It slides in and out of its lockable box and is secured by a spring-loaded catch. When a transaction that involves cash is completed, the register sends an electrical impulse to a solenoid to release the catch and open the drawer. Cash drawers that are integral to a stand-alone register often have a manual release catch underneath to open the drawer in the event of a power failure. More advanced cash drawers have eliminated the manual release in favor of a cylinder lock, requiring a key to manually open the drawer. The cylinder lock usually has several positions: locked, unlocked, online (will open if an impulse is given), and release. The release position is an intermittent position with a spring to push the cylinder back to the unlocked position. In the "locked" position, the drawer will remain latched even when an electric impulse is sent to the solenoid. Some cash drawers are designed to store notes upright & facing forward, instead of the traditional flat and front to back position. This allows more varieties of notes to be stored. Some cash drawers are flip top in design, where they flip open instead of sliding out like an ordinary drawer, resembling a cashbox instead.


Management functions

An often used non-sale function is the aforementioned "no sale". In case of needing to correct change given to the customer, or to make change from a neighboring register, this function will open the cash drawer of the register. Where non-management staff are given access, management can scrutinize the count of "no sales" in the log to look for suspicious patterns. Generally requiring a management key, besides programming prices into the register, are the report functions. An "X" report will read the current sales figures from memory and produce a paper printout. A "Z" report will act like an "X" report, except that counters will be reset to zero.


Manual input

Registers will typically feature a numerical pad,

or custom keyboard, touch screen interface, or a combination of these input methods for the cashier to enter products and fees by hand and access information necessary to complete the sale. For older registers as well as at restaurants and other establishments that do not sell barcoded items, the manual input may be the only method of interacting with the register. While customization was previously limited to larger chains that could afford to have physical keyboards custom-built for their needs, the customization of register inputs is now more widespread with the use of touch screens that can display a variety of point of sale software.


Scanner

Modern cash registers may be connected to a handheld or stationary

so that a customer's purchases can be more rapidly scanned than would be possible by keying numbers into the register by hand. The use of scanners should also help prevent errors that result from manually entering the product's barcode or pricing. At grocers, the register's scanner may be combined with a scale for measuring product that is sold by weight.


Receipt printer

Cashiers are often required to provide a receipt to the customer after a purchase has been made. Registers typically use thermal printers to print receipts, although older

are still in use at some retailers. Alternatively, retailers can forgo issuing paper receipts in some jurisdictions by instead asking the customer for an email to which their receipt can be sent. The receipts of larger retailers tend to include unique barcodes or other information identifying the transaction so that the receipt can be scanned to facilitate returns or other customer services.
