What is an ATM?
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.
History of ATM
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 New York City by the City Bank of New York
The first person to use the machine was Reg Varney of "On the Buses" fame, a British Television 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 Don Wetzel in 1968
Notable historical models of ATMs include the IBM 3624 and 473x series, Diebold 10xx and TABS 9000 series, and NCR 5xxx series.

ATM cards: How to use an ATM?
The customer is identified by inserting a plastic ATM card with a magnetic stripe or a plastic smartcard with a chip that contains the unique card number and security information.
Security is provided by the customer entering a personal identification number (PIN).
Upon successful entry of the PIN, the customer may perform a transaction.
The ATM calls up the bank's computers to verify the balance, dispenses the cash and then transmits a completed transaction

Input devices of ATM:Card reader and Keypad
The card reader captures the account information stored on the magnetic stripe on the back of an ATM/debit or credit card. The host processor uses this information to route the transaction to the cardholder's bank.
The keypad lets the cardholder tell the bank what kind of transaction is required (cash withdrawal, balance inquiry, etc.) and for what amount. Also, the bank requires the cardholder's personal identification number (PIN) for verification. Federal law requires that the PIN block be sent to the host processor in encrypted form.
Output devices of ATM:Display screen, cash dispenser and receipt printer
Display Screen:
The display screen prompts the cardholder through each step of the transaction process. Leased-line machines commonly use a monochrome or colour CRT (cathode ray tube) display. Dial-up machines commonly use a monochrome or colour LCD.
Cash dispenser and Receipt Printer:
The heart of an ATM is the safe and cash-dispensing mechanism. The entire bottom portion of most small ATMs is a safe that contains the cash.
The receipt printer provides the cardholder with a paper receipt of the transaction.
Requirements of ATM
HARDWARE REQUIREMENTS
Processor : Processorx86 Family 6 Model 15 Stepping 13 GenuineIntel~2394Mhz
RAM : 512 MB or more
Hard disk : 20 GB or more
Monitor : VGA/SVGA
Keyboard : 104 Keys
Mouse : 2 buttons/ 3 buttons
SOFTWARE REQUIREMENTS

Database : Ms-Access.
CAL protocols such as Diebold 911 or 912 are replace by new protocols as IFX
ATM Networking
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 tra nsaction, he or she provides the necessary information by means of the card reader and keypad.
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.
How do ATMs work?
Advantages and disadvantages of ATM
Advantages
ATM supports voice, video and data allowing multimedia and mixed services over a single network.
Provides the best multiple service support
Supports delay close to that of dedicated services
Able to use all common physical transmission paths like SONET.
Cable can be twisted-pair, coaxial or fiber-optic
Ability to connect LAN to WAN
Legacy LAN emulation
Efficient bandwidth use by statistical multiplexing
Higher aggregate bandwidth
High speed Mbps and possibly Gbps
Disadvantages
Flexible to efficiency’s expense, at present, for any one application it is usually possible to find a more optimized technology
Cost, although it will decrease with time
New customer premises hardware and software are required
Competition from other technologies -100 Mbps FDDI, 100 Mbps Ethernet and fast Ethernet
Presently the applications that can benefit from ATM such as multimedia are rare
The wait, with all the promise of ATM’s capabilities many details are still in the standards process
Location and types of ATM
ATMs are placed not only near or inside the premises of banks, but also in locations such as shopping centers/malls, airports, grocery stores, petrol/gas stations, restaurants, or any place large numbers of people may gather.

Make your PIN a series of numbers that you can easily memorise and avoid using common dates and numbers related to your life.
Don’t write down your PIN and keep it in a place where it can be easily found. Keep your ATM card in safe places. Keep your PIN a secret and don’t disclose confidential information about your card over the telephone or the Internet.
Observe the surroundings at the ATM location before conducting a transaction.
Block the view of others when using an ATM to make sure they cannot see your PIN.
Look for possible fraudulent devices attached to an ATM. If anything looks suspicious, use another machine.
Never allow a cashier or any other person to enter your PIN for you.
Have your card ready to minimize the time you spend at an ATM.
When using a drive-up ATM after dark, keep your car doors locked, passenger windows rolled up and headlights on when conducting your transaction.
If using an ATM at night, try to take someone with you.
Check your ATM receipts against your monthly credit union statements, just as you do your cancelled checks.
If you think you are being followed after leaving an ATM, call 911 or look for a police officer.
After transaction, take your receipt, collect your ATM card and leave the place immediately. Do not count the money in there.

Transaction is possible any time, that’s why in India some people call ATM as “all time money”. If ATM machines are connected to internet then its possible to do transaction from any where, 24 hours a days and 365 days a year. With the security of ATM improving it has now become a safe mode of transaction. Hence it can be concluded that ATM is safe, fast, reliable, convenient, excisable and any time money machine.
