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

PROPOSED SYSTEM
-
8/7/2019 VASANTH Project Report
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.
-
8/7/2019 VASANTH Project Report
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.
-
8/7/2019 VASANTH Project Report
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.

BREAKS ON VARIABLES:-
Here, Breaks were put on a particular variable and it was checked that whether it contains the
expected value or not, whenever the variable changes the value through out the Module. This
procedure was repeated twice for all the important global variables in a project.
The same above procedure was implemented for variables global to the whole system.
