What is an
An automated teller machine (ATM) is a computerized
telecommunications device that provides the customers of a
financial institution or bank with access to financial transactions in
a public space without the need for a human clerk or bank teller 24
hours a day.
ATMs plays a vital role in facilitating the banking services to banks
as well as customers.
ATM is the back bone of retail banking sector.
The word "machine" in the term "ATM machine" is certainly
redundant, but widely used.
The ATM was invented by Scot John Shepherd-Barron.
The world's first ATM was installed in a branch of Barclays in the
northern London borough of Enfield, Middlesex, in 1967.
A mechanical cash dispenser was developed and built by Luther
George Simjian and installed in 1939 in NewYork City by the City
Bank of NewYork
The first person to use the machine was RegVarney of "On the
Buses" fame, a BritishTelevision programme from the 1960s
The idea of a PIN stored on the card was developed by the British
engineer John Rose in 1965.
The modern, networked ATM was invented in Dallas,Texas, by
DonWetzel in 1968
Notable historical models ofATMs include the IBM 3624 and 473x
series, Diebold 10xx andTABS 9000 series, and NCR 5xxx series.

An ATM is simply a data terminal with two input and four output
devices. Like any other data terminal, the ATM has to connect to
and communicate through a host processor.
Leased-line machines connect directly to the host processor through
a four-wire, point-to-point, dedicated telephone line.
Dial-up ATMs connect to the host processor through a normal phone
line using a modem and a toll-free number, or through an Internet
service provider using a local access number dialed by modem.
When a cardholder wants to do an ATM transaction, he or she
provides the necessary information by means of the card reader and
ATM forwards this information to the host processor, which routes
the transaction request to the cardholder's bank or the institution that
issued the card.
If the cardholder is requesting cash, the host processor causes an
electronic funds transfer to take place from the customer's bank
account to the host processor's account.
Once the funds are transferred to the host processor's bank account,
the processor sends an approval code to the ATM authorizing the
machine to dispense the cash.

services over a single network.

ATMs are placed not only near or inside the premises of banks, but
also in locations such as shopping centers/malls, airports, grocery
