INTRODUCTIONINTRODUCTION

An An automated teller machineautomated teller machine ( (ATMATM) is a computerized telecommunications device ) is a computerized telecommunications device that provides the customers of a financial institution with access to financial that provides 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 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 with a most modern ATMs, the customer is identified by inserting a plastic ATM card with a magnetic stripe or a plastic smartcard with a chip, that contains a unique card 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). 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).Security is provided by the customer entering a personal identification number(PIN).

Using an ATM, customers can access their bank accounts in order to make cash Using an ATM, customers can access their bank accounts in order to make cash withdrawals (or credit card cash advances) and check their account balances as well withdrawals (or credit card cash advances) and check their account balances as well as purchasing mobile cell phone prepaid credit.as purchasing mobile cell phone prepaid credit.

ATMs are known by various other names including ATMs are known by various other names including automated banking machineautomated banking machine, , money machinemoney machine, , bank machinebank machine, , cash machinecash machine, , hole-in-the-wallhole-in-the-wall, , cashpointcashpoint, , BancomatBancomat (in various countries in Europe and Russia), (in various countries in Europe and Russia), MultibancoMultibanco and and Any Time MoneyAny Time Money eased eased ATM usage is also helped by the fact that customers have now the flexibility of using ATM usage is also helped by the fact that customers have now the flexibility of using ATMs of other banks, as most of the banks are part of major interbank networks like ATMs of other banks, as most of the banks are part of major interbank networks like National Financial Switch (NFS), Milr, BANGS, Cashtree and Cashnet. The interbank National Financial Switch (NFS), Milr, BANGS, Cashtree and Cashnet. The interbank networks have brought together ATMs of several banks so that consumers would gain networks have brought together ATMs of several banks so that consumers would gain access to any of the participating banks' ATMs. access to any of the participating banks' ATMs.

SCOPE OF THE PROJECTSCOPE OF THE PROJECT Keeping the problem in mind, we have developed a solution which would help the bank, achieve its Keeping the problem in mind, we have developed a solution which would help the bank, achieve its

overall objectives. The application can be securely accessed by bank employees & the administrator overall objectives. The application can be securely accessed by bank employees & the administrator who has got system-level rights to access confidential information of the bank employees in the who has got system-level rights to access confidential information of the bank employees in the database.database.

LIMITATIONS AND CONSTAINTS OF LIMITATIONS AND CONSTAINTS OF THE PROJECTTHE PROJECT

Researchers who work for an Israeli computer security Researchers who work for an Israeli computer security company say they have discovered a fundamental company say they have discovered a fundamental weakness in the system that banks use to keep debit card weakness in the system that banks use to keep debit card PIN codes secret while they are transported across bank PIN codes secret while they are transported across bank networks - a flaw that they say could undermine the entire networks - a flaw that they say could undermine the entire debit card system.Accordingly its limitations include three debit card system.Accordingly its limitations include three types of feasibility:-types of feasibility:-

Economic Feasibility:Economic Feasibility: Economic analysis includes the use Economic analysis includes the use or rather n some sense misuse of the ATM machines in or rather n some sense misuse of the ATM machines in foreing countries. it can be misuse in any part of the world. foreing countries. it can be misuse in any part of the world. the money can be used by some unauthorized agency for the money can be used by some unauthorized agency for their brutal purpose. again here the verification of the PIN their brutal purpose. again here the verification of the PIN no. plays a very important role. ln the financial sector this is no. plays a very important role. ln the financial sector this is regarded as the PIN cracking.regarded as the PIN cracking.

Technical Feasibility:Technical Feasibility: Technical feasibility includes the Technical feasibility includes the proper functioning of atm database system when it comes proper functioning of atm database system when it comes to the remembering of the PIN no. Many cardholders walk to the remembering of the PIN no. Many cardholders walk up to an ATM and pull out a piece of paper containing four up to an ATM and pull out a piece of paper containing four numbers. If you are not sure, make it a point that you don't numbers. If you are not sure, make it a point that you don't keep the PIN and ATM card together in your wallet - If keep the PIN and ATM card together in your wallet - If someone comes up and hits you over the head, they're someone comes up and hits you over the head, they're going to have all your information right there. But ideally, going to have all your information right there. But ideally, one should never write down the PIN number - it should be one should never write down the PIN number - it should be memorized.memorized.

Social Feasibility: Social Feasibility: Illiterate People cant handle the Illiterate People cant handle the functioning of ATM. So to teach them the use instructions functioning of ATM. So to teach them the use instructions are also provided regarding its transactions & debits, are also provided regarding its transactions & debits, transfer of money to people at any part of the worldtransfer of money to people at any part of the world
