An automated teller machine (ATM) is an electronic telecommunications device that enables customers of financial institutions to perform financial transactions, such as cash withdrawals, deposits, funds transfers, balance or account information inquiries, at any time and without the need for direct interaction with bank staff. ATMs are known by a variety of other names, including automatic teller machines (ATMs) in the United States (sometimes redundantly as "ATM machine"). In Canada, the term automated banking machine (ABM) is also used, although ATM is also very commonly used in Canada, with many Canadian organizations using ATM rather than ABM. In British English, the terms cashpoint, cash machine and hole in the wall are also used. ATMs that are not operated by a financial institution are known as "white-label" ATMs. Using an ATM, customers can access their bank deposit or credit accounts in order to make a variety of financial transactions, most notably cash withdrawals and balance checking, as well as transferring credit to and from mobile phones. ATMs can also be used to withdraw cash in a foreign country. If the currency being withdrawn from the ATM is different from that in which the bank account is denominated, the money will be converted at the financial institution's exchange rate. Customers are typically identified by inserting a plastic ATM card (or some other acceptable payment card) into the ATM, with authentication being by the customer entering a personal identification number (PIN), which must match the PIN stored in the chip on the card (if the card is so equipped), or in the issuing financial institution's database. According to the ATM Industry Association (ATMIA), as of 2015, there were close to 3.5 million ATMs installed worldwide. However, the use of ATMs is gradually declining with the increase in cashless payment systems.
History The idea of out-of-hours cash distribution was first put into practice in Japan, the United Kingdom, and Sweden. In 1960, Armenian-American inventor Luther Simjian invented an automated deposit machine (accepting coins, cash and cheques) although it did not have cash dispensing features. His US patent was first filed on 30 June 1960 and granted on 26 February 1963. The roll-out of this machine, called Bankograph, was delayed by a couple of years, due in part to Simjian's Reflectone Electronics Inc. being acquired by Universal Match Corporation. An experimental Bankograph was installed in New York City in 1961 by the City Bank of New York, but removed after six months due to the lack of customer acceptance. In 1962, Adrian Ashfield invented the idea of a card system to securely identify a user and control and monitor the dispensing of goods or services. This was granted UK Patent 959,713 in June 1964 and assigned to Kins Developments Limited.
Invention In 1966, a Japanese device called the "Computer Loan Machine" dispensed cash as a three-month loan at an annual interest rate of 5% upon inserting a credit card. However, little is known about the device.
A cash machine was installed at Barclays Bank, Enfield, North London in the United Kingdom, on 27 June 1967. This is generally considered the world's first ATM. This machine was inaugurated by English actor Reg Varney as part of the launch publicity. This invention is credited to the engineering team led by John Shepherd-Barron of printing firm De La Rue, who was awarded an OBE in the 2005 New Year Honours. Transactions were initiated by inserting paper cheques issued by a teller or cashier, marked with carbon-14 for machine readability and security, which in a later model were matched with a four-digit personal identification number (PIN). Shepherd-Barron stated: It struck me there must be a way I could get my own money, anywhere in the world or the UK. I hit upon the idea of a chocolate bar dispenser, but replacing chocolate with cash.
The Barclays–De La Rue machine (called De La Rue Automatic Cash System or DACS) beat the Swedish saving banks' and a company called Metior's machine (a device called Bankomat) by a mere nine days and British Westminster Bank's Smith Industries Chubb system (called Chubb MD2) by a month. The online version of the Swedish machine is listed to have been operational on 6 May 1968, while claiming to be the first online ATM in the world, ahead of similar claims by IBM and Lloyds Bank in 1971, and Oki in 1970. The collaboration of a small start-up called Speytec and Midland Bank developed a fourth machine which was marketed after 1969 in Europe and the US by the Burroughs Corporation. The patent for this device (GB1329964) was filed in September 1969 (and granted in 1973) by John David Edwards, Leonard Perkins, John Henry Donald, Peter Lee Chappell, Sean Benjamin Newcombe, and Malcom David Roe. Both the DACS and MD2 accepted only a single-use token or voucher which was retained by the machine, while the Speytec worked with a card with a magnetic stripe at the back. They used principles including Carbon-14 and low-coercivity magnetism in order to make fraud more difficult. The idea of a PIN stored on the card was developed by a group of engineers working at Smiths Group on the Chubb MD2 in 1965 and which has been credited to James Goodfellow (patent GB1197183 filed on 2 May 1966 with Anthony Davies). The essence of this system was that it enabled the verification of the customer with the debited account without human intervention. This patent is also the earliest instance of a complete "currency dispenser system" in the patent record. This patent was filed on 5 March 1968 in the US (US 3543904) and granted on 1 December 1970. It had a profound influence on the industry as a whole. Not only did future entrants into the cash dispenser market such as NCR Corporation and IBM license Goodfellow's PIN system, but a number of later patents reference this patent as "Prior Art Device".
