ATM Full Form
What is the full form of ATM?
The
Full form of ATM is Automated Teller Machine (Banking and Finance).
Another
full form of ATM is Asynchronous Transfer Mode (Information Technology).
Automated Teller Machine
Automated
teller machine (ATM) is an electronic telecommunications apparatus, which permits
the clients of financial institutions (e.g., banks) to execute monetary
transactions, such as cash withdrawals, deposits, fund transfers, or account
information inquiries, anytime around the clock without having direct
interaction with the staffs of that financial institute (e.g., bank employees).
The
basic ATMs are equipped with only one option, cash withdrawals. The advanced
ATMs apart from cash withdrawals have multiple functionalities including cash
dispensing, PIN generation, cheque deposition, fund transfer, balance inquiry,
mini statement generation, bill payment, and mobile recharge.
How do ATMs function?
In
simple words, ATM is a data terminal consisting of two input and four output
devices.
Input
devices — Keypad and Card reader
Output
devices – Display screen, Speaker, Cash dispenser, and Receipt printer
Input Devices
Card reader
This
input device reads securely stored data from the magnetic stripe on the back of
the ATM card (i.e., a plastic card provided by the bank or financial institute
with personal banking information encoded). Once the card is put into the card
reader (either by swapping or dropping) this device reads the account
information and transfers it to the server (host processor). The server utilizes
this information to route the transaction to the cardholder’s bank or financial
institute.
Keypad
When
the system recognizes a card is inserted or swapped into the card reader it
asks the consumer to enter the Personal identification number (PIN is a 4 digit
security number provided by the bank with the ATM card. PIN number is
changeable, you can modify it according to your suitability). The PIN number is
sent in the encrypted form to the server. If the PIN is found correct, the
system suggests further options, like withdrawal, balance inquiry, amount of cash, receipt required or
not, etc. (the names of the functions are diverse and varies from one ATM model
to another). Besides the aforementioned functions, the keypad can help the
cardholder to cancel a transaction or correct it.
Output Devices
Speaker
The
speaker offers the consumer help with audio feedback when a key is pressed or
alerts about the success or failure of an operation.
Display screen
The
screen visibly shows the cardholder every step of the transaction process when
he provides inputs or the outcome of his/ her requests. CRT or LCD screens are
the most common visual devices that ATMs are endowed with.
Receipt printer
This
small output device attached to ATMs prints a paper receipt with all details of
the transaction. It also provides the customer a physical proof if a
transaction is failed or disputed due to some technical error.
Cash dispenser
It
is the main output device of the ATM as it dispenses the cash. The cash
dispenser has a special high precision sensor that counts each banknote. This
mechanism takes information about the specified number of the bills (number,
entered by cardholder) and passes the bills to the special sensors. These
sensors verify banknote authenticity and check whether or not banknotes are
flocked together and dispense
the correct amount of cash as required by the user. All the activity
information is recorded in a special journal.
Working Principle
Once
the cardholder wants to execute a transaction, they need to hold their cards
into the card reader and provide the ATM system with all the compulsory
information. The ATM system transfers the data to the host processor, which
transmits the operation request to the user’s bank or financial institute. When
a consumer requests cash, the host processor submits an electronic funds
transfer request from the user’s bank account to the host processor’s account. The
processor sends an approval code to the ATM system and directs for cash
dispensing if the money had been successfully transferred from the user’s bank
account to the processor’s account.
Different names of ATM around the world
- Automatic Teller Machine (ATM) - United States
- Automated Banking Machine (ABM) – Canada
- Cashpoint, Cash Machine and Hole in the wall - British English,
- Any Time Money, Cashline, Nibank, Tyme Machine, Cash Dispenser, Cash Corner, Bankomat, or Bancomat – different regions.
- "White-Label" ATMs - ATMs that are not operated by a financial institution are known as.
Origin of the ATM
Adrian
Ashfield invented the rudimentary idea of a card linking the key and user's
identity (February 1962). A UK Patent was granted (No. 959,713) for
"Access Controller" to W. S. Atkins & Partners who employed Ashfield
(June 1964). It was initially projected to dispense petrol but the patent
covered all uses.
The
first ATM of the world was installed at the Barclays Bank of London (27th June
1967). The first ATM that was used to dispense cash for customers was installed
by Chemical bank at New York (USA) (1969). In India, the first ATM was installed
by HSBC (Hongkong and Shanghai Banking Corporation) (1987).
Asynchronous Transfer Mode
In
networking technology ATM stands for "Asynchronous Transfer Mode."
What is Asynchronous Transfer Mode?
In
the computer world, the Asynchronous Transfer Mode is a networking technology
that transfers data in packets or cells of a fixed size.
ATM
uses 53-byte cells (5 bytes for the address header and 48 bytes for the data).
These enormously tiny cells are processed through an ATM switch sufficiently fast
to sustain data transfer speeds of over 600 Mbps. The ATM technology was aimed at
the high-speed transmission of all types of media starting from basic graphics
to full-motion video. As the cells are very tiny, the ATM apparatus is able to
transmit humongous amounts of data over a single connection while guaranteeing
that no single transmission is using up all the bandwidth. It further permits the
Internet Service Providers (ISPs) to allocate limited bandwidth to each consumer.
Although this apparently looks like a disadvantage to the consumer, it essentially
improves the efficiency of the ISP's Internet connection. As a result, the
overall speed of the connection becomes faster for one and all.
