    • Product Perspective•An automated teller machine (ATM) is a computerized telecommunications devicethat provide the customers of a financial institution with access to financial transactions in a public space without the need for a human clerk or bank teller. On most modern ATMs, the customer is identified by inserting a plastic ATM card witha magnetic stripe or a plastic smartcard with a chip, that contains a unique card number and some security information, such as an expiration date or CVC (CVV). Security is provided by the customer entering a personal identification number (PIN).
    • Computerized machine that permits bankcustomers to gain access to their accountswith a magnetically encoded plastic card and acode number. It enables the customers toperform several banking operations withoutthe help of a teller, such as to withdrawcash, make deposits, pay bills, obtain bankstatements, effect cash transfers. Also calledautomated Banking machine, automatic tillmachine, or remote service unit
    • Using an ATM, customers can access theirbank accounts in order to make cash withdrawals (or credit card cash advances) andcheck their account balances.The functions of the system are: 1. Login 2. Get Balance Information 3. Withdraw Cash 4. Generate receipt
    • There are several users of the ATM network• Customer: The customer interacts with the ATMnetwork via the ATM It must be very easy forthem to use the ATM . They should besupported by the system in every possibleway•Maintainer:It should be easy to maintain the wholesystem The maintainer should be the onlyperson that is allowed to connect a new ATMto the network
    • •Some of the constraints that have to betaken care of with respect to the softwaredevelopment could be the platform wherethe software is to be run should have anaccess to MS-ACCESS . The end userneeds to have basic computer knowledge .• The user may fail to exactly explain hisrequirement however his requirements areanalyzed and understood by the developer, as the software is a generic one.
    • •Some companies that manufacture ATMs areMERCHANT BANKARDNETWORK, HITACHI, AUSTRIAN BANKINGAOTOMATION SYSTEM INTEGRATOR.•At the end of this report I conclude with the followingpoints:- With the growing networks ATM might soon beinstalled at many places.- ATMs for the blind have also been designed & areavailable in the Chinese market.- ATMs that make available various types ofcurrencies are also available
    • •An ATM is simply a data terminal with two input andfour output devices. Like any other data terminal theATM has to connect to, and communicate through, ahost processor.•The host processor is analogous to an InternetService Provider (ISP) in that it is the gatewaythrough which all the various ATM networks becomeavailable to the cardholder .Most host processors can support either leased-lineor dial-up machines.•Leased-line machines connect directly to the hostprocessor through a four-wire, point-to-point, dedicated telephone line.•Dial-up ATMs connect to the host processor througha normal phone line or through an Internet service
    • •Leased-line machines commonly use a monochromeor color CRT (cathode ray tube) display.•Dial-up machines commonly use a monochrome orcolor LCD.•The host processor may be owned by a bank orfinancial institution, or it may be owned by anindependent service provider.•Bank-owned processors normally support only bank-owned machines, whereas the independentprocessors support merchant-owned machines

    • Various protocols are used for transferringinformation over the network in the ATM. A fewof them are explained in brief:1. TCP (Transmission control protocol):- Connection oriented protocol.- TCP is used to dynamically adapt to propertiesof the internetwork & to be robust to face anyfailures.2. SMTP (Simple Mail Transfer Protocol):- Simple ASCII protocol, Accepts incomingmessages & sends them to appropriatelocations.
    • •As most of the ATMs are open for 24 hrs & alsoall of them are not guarded, it is important toprovide security to the machine. One of thetechnologies is explained here.•The Electronic Signature Lock (ESL) is apatented technology that can be implemented inhardware, firmware, or software and used toprotect digital resources, funds transfer, orphysical access. It can identify computerterminal users locally or remotely without havingto modify or attach anything to the terminal. It iscompletely transparent to the users and can be
