INTRODUCTION

Existing System:

1. The bank doesnt have the ATM and Tele Banking facility.

2. The bank has a computerized system.

3. Any customer of bank has to form queue and do any transaction or transaction

information.

Limitation of Existing System:

1. Lack of transactional security.

2. Less reliable and efficient.

3. The customer has to form queue and hence time consuming.

4. Work load on the part of staff members.

Problem Statement:

1. Due to increasing proficiency in the current world of technology the organization has

to up to date as well as be superior operational to maintain good reputation in

competitive environment. In order to be well operational one need to be quick and

accurate. Use of technology enables the institution to be quick as well as precise.


5/48

2. Since the existing system is computerized but dont have the facility of ATM and

TELE Banking, the customer cant withdraw the money or have the account

information 24 x 7.

3. The proposed system help the customer to perform account information (withdraw,

balance enquiry, print mini-statement) through ATM banking and to withdraw the

money through TELE banking.

4. The new details can be entered and previous details can be easily modified or delete

with the aid of proposed system.

5. It helps the bank administrator to view all users and modify, delete data.

Software Requirement Specification: -

The software is developed on Microsoft Visual Basic 6.0 as Front End and

Microsoft SQL Server 2000 or Microsoft access 2003 as Back End.

ATM Banking

The actors of the system are:

1. User

2. ATM Machine

3. Bank

Scope:

The software supports a computerized banking. The system enables a customer to

complete simple banking services via ATM machine that may be located off premise. The ATM

identifies the customer by Cash Card and password. It collects information about a simple

account transaction (withdraw, deposit, balance enquiry) communicates the transaction


6/48

information to the customers bank, and dispenses cash to the customer. The software also

provides provision to record keeping and security. The software handles the concurrent access to

the account correctly.

Product perspective:

Hardware interface: The software run on an ATM machine installed by Bank.

Software interface: The system is able to connect to the Banks administrator computer at

any given time

Functional Requirement:

The functions of the system are:

1. Login

2. Get Balance Information

3. Withdraw Cash

4. Get mini-statement

5. Changing Pin number

PROPOSED SYSTEM


10/48

Need for Proposed System:

1. The proposed system will help the organization to add ATM and TELE banking

facility, and maintain the records of customer.

2. The customers dont have to form queue and hence it is time effective.

3. There is more transactional security.

Proposed System:

ATM BANKING:

ATM Service consists of ATM Card and ATM pin. ATM Card has all the

information of the customer, which can be accessed by the system. Each

ATM card holder has to select his/her PIN that is Personal Identification

Number to gain access from any ATM and to operate the account. Any

wrong pin fed to ATM Machine for more than three occasions, it will

retain the card.

After completion of transaction, if ATM card remains un-retrieved, it is

assumed as forgotten and ATM card safely retains it, and can be retrieved

from CIB (Card Issuing Branch).

TELE Banking:

TELE banking service helps the customer to withdraw money by dialing a

telephone to the bank. In this, the customer dials a secret code, card

number and then dials his account number. The bank verifies the

information and then dials his account number. The bank verifies thisinformation and then allows the customer to dial specific amount of

money that the customer wants to withdraw. After this process, within 24

hours banks employee delivers specified money to customer. Objectives

of Proposed System:

ATM Features: -

The facilities offered by ATM System are as follows:

1. Withdrawal of cash by Card Holder from his AATM account up to certain amount

limit only as fixed by bank.

2. Enquiry of the balance can be done.

3. Request for statement of account.

4. Any additional facilities made available by bank from time to time.


11/48

TELE Features: -

The facilities offered by TELE System are as follows: -

1. Withdrawal of cash is done from TELE account up to a certain amount limit fixed by

bank from time to time. Money withdraws from the account reaches the user within24-hours from the time of withdrawal.

2. Any additional facilities made available by bank from time to time.

User Requirements: -

User requirements focus on experience user need to have with the system, with no

concern for the inner workings of the system. The system shall complete a standard withdrawal

from a personal account, from login to cash, in less than 2 minutes for a first time user.

The customer user interface should be intuitive, such that all new ATM users are able

to complete their banking transactions without any assistance.

TELE banking is a system where users have to dial and enter a pin number, so it is

not necessary for user to have great knowledge of inner working of TELE banking. The system

itself is least complicate.

Description

ATM A station which allows customers to enter their own

transactions using cash cards as identification. The ATM

interacts with the customer to gather transaction

information, sends the transaction information to the

central computer for validation and processing and

dispenses cash to the user. We assume that the ATM

need not operate independently of the network.

Account A single account at a bank against which the transactions

can be applied. Accounts can be of many types: checking

and savings. A customer can hold more than one account.

Bank A financial institution that holds accounts for customers

and issues cash cards authorizing access to accounts over

the ATM network.

Custome

r

The holder of one or more Accounts in a Bank. A customer

may consist of one or more persons or corporations; the

correspondence is not relevant to this problem. The same

person holding an Account at a different Bank is

considered a different customer.

Transacti

on

A single integral request for service w.r.t. the Accounts of

a single Customer.

This request will help the customer to withdraw money

through cash dispenser, balance check, and print mini-

statement.


15/48

Cash

card

A card assigned to each Customer authorizing access to

accounts: via an ATM. Each contains a bank code and a

card number. The card number determines the Accounts

the card may access. Each cash card is owned by a single

Customer.

The magnetic strip behind the card provides the personal

details of customer for authentication.

Manager A Bank employee authorized to enter Transactions into a

Bank Station and accept and dispense cash to Customers.

Transactions, cash and transaction information handled by

each manager must be logged and properly accounted

for.

User A customer with bank and uses the ATM and Tell banking

facility

TELE TELE service helps the customer to withdraw money by

dialing a telephone to the bank. In this, the customer dials

a secret code, card number and then dials his account

number. The bank verifies the information and then dials

his account number. The bank verifies this information

and then allows the customer to dial specific amount of

money.

CheckPIN

The CheckPIN procedure handles the verification of the customer's Personal Identification

Number (PIN) using data retrieved from the card's magnetic strip. The procedure invites the

customer to enter their PIN using the keypad. If this does not match the PIN stored on the card, a

limited number of retries is permitted, after which the card is confiscated as a security

precaution. If the correct PIN is entered, the Services procedure is called.

Services

The Services procedure presents a menu of the options which are currently available to

customers. The customer selects an option by pressing a key on the keypad. The key is identified

and the relevant option is activated. After processing an option the procedure will do one of two

things. If a 'Withdrawal...' or 'Return Card' option was selected, the procedure will terminate. If

any one of the other options were selected, the selection process is repeated to allow the

customer to use another service. The options which request a cash withdrawal call the

Withdrawal procedure.

Withdrawal

The Withdrawal procedure handles the process of withdrawing cash from the customer's account.

It receives one parameter which indicates the type of withdrawal (i.e. with or without a printed

receipt). The customer is first presented with a list of cash values to select from and an option to

enter their own value explicitly. Once a value has been specified, the customer's account details

are checked in the Accounts Database. If there are no funds available, the customer is informed,

the card is returned and the procedure terminates. If the customer has insufficient funds to cover

the requested amount, the actual amount available is offered. If this reduced offer is declined, the

customer's card is returned and the procedure terminates. If an available amount is specified, the

card is first returned to ensure it is not forgotten. The cash is then dispensed and, if required, a

receipt is printed. The customer's account details are then updated in the Accounts Database and

the procedure terminates.
