teller machine (ATM), insert your card into the card reader,respond to the prompts on the screen, and within a minute

WORKING of ATMs


4/21

An ATM is simply a data terminalwith two inputs(card readerand key pad) and four output devices(speaker, display screen,receipt printer and cash dispenser).

Like any other data terminal, the ATM has to connect to, andcommunicate through, a host processor. The host processor isanalogous to an Internet service provider (ISP) in that it is thegateway through which all the various ATM networks becomeavailable to the cardholder (the person wanting the cash).

The host processor may be owned by a bank or financialinstitution, or it may be owned by an independent serviceprovider. Bank-owned processors normally support only bank-owned machines, whereas the independent processors support

merchant-owned machines.

INPUTS AND OUTPUTS OF ATM Card reader - The card reader captures the account

information stored on the magnetic stripe on the backof an ATM/debit or credit card. The host processoruses this information to route the transaction to thecardholder's bank.

Keypad - The keypad lets the cardholder tell thebank what kind of transaction is required (cash

withdrawal, balance inquiry, etc.) and for whatamount. Also, the bank requires the cardholder'spersonal identification number (PIN) for verification.

Federal law requires that the PIN block be sent to the

host processor in encrypted form.And an ATM has four output devices:

Speaker - The speaker provides the cardholder withauditory feedback when a key is pressed.

Display screen - The display screen prompts thecardholder through each step of the transactionprocess. Leased-line machines commonly use amonochrome or color CRT (cathode ray tube) display.Dial-up machines commonly use a monochrome orcolor LCD.
