PROJECT ABSTRACT
The ATM System is the project which is used to access their bank accounts in order to
make cash withdrawals. Whenever the user need to make cash withdraws, they can
enter their PIN number (personal identification number) and it will display the amount
to be withdrawn in the form of 50’s,100’s and 500’s. Once their withdrawn was
successful, the amount will be debited in their account.
The ATM System is developed in VB.Net and back-end database as Ms-Access. VB.Net is
the one of the powerful version of Framework and object oriented programming. Hence
we use this software in our project.
The ATM will service one customer at a time. A customer will be required to enter ATM
Card number, personal identification number (PIN) – both of which will be sent to the
database for validation as part of each transaction. The customer will then be able to
perform one or more transactions. Also customer must be able to make a balance
inquiry of any account linked to the card.
The ATM will communicate each transaction to the database and obtain verification that
it was allowed by the database. In the case of a cash withdrawal, a second message will
be sent after the transaction has been physically completed (cash dispensed or envelope
accepted). If the database determines that the customer’s PIN is invalid, the customer
will be required to re-enter the PIN before a transaction can proceed.
If a transaction fails for any reason other than an invalid PIN, the ATM will display an
explanation of the problem, and will then ask the customer whether he/she wants to do
another transaction.
The ATM will provide the customer with a printed receipt for each successful
transaction, showing the date, time, machine location, type of transaction, account(s),
amount, and ending and available balance(s) of the affected account (“to” account for
transfers).

1. Introduction:
Automated Teller Machine enables the clients of a bank to have access to their account
without going to the bank. This is achieved only by development the application using
online concepts.
When the product is implemented, the user who uses this product will be able to see all
the information and services provided by the ATM, when he enters the necessary option
and arguments. The product also provides services like request for cheques, deposit
cash and other advanced requirement of the user. The data is stored in the database and
is retrieved whenever necessary. The implementation needs ATM machine hardware to
operate or similar simulated conditions can also be used to successfully use the
developed product.
To develop this ATM system the entire operation has been divided into the following
step:
1. verification process
2. language, service and account selection
3. Banking services
4. Transactions
5. Special services
The program is designed in such a way that the user has to card and pin number. Once
verified, he is provided a menu and he/she had to enter the option provided in the
menu. For example, when the user wants to view the list of payment history than
he/she had to enter the option for payment history provided in the main menu. When
the option is entered alone with the respective argument, then the payment history is
displayed on the screen.
The user also must be given option to browse through the pages like previous page, next
page, etc. The user may experience a delay in retrieving or viewing the data, when there
are many users logged on to the same bank branch system.

1.2. Problem definition :
The system mainly used by the bank clients. When a client comes to ATM centre to
update and delete their account. It reduces the time consumption and lot of paperwork.
For any single operation it involves numerous references and updating also takes
subsequent changes in other places.
1.3. Evidence of problem definition:
Now- a -days every one very busy in their work. So they feel that the job must be easier
so the system is used to reduce their work which is done in the ATM system. Instead of
keeping lots of paper into a record or file and it may be missed somewhere so, this
system help to keep the record of the customer it also keeps the details of the customer.
It is also easy to access.
1.4. Proposed solution:
The system customer transactions, satisfies the requirements of the existing system in
full-fledged manner. Through this system, customer can make fast transactions and
view the last transactions easily.
1.5. Scope :
 It can be implemented in ATM machine by owner of bank or in charge of branch.
 It is easy to learn the task.
1.6. Objectives:
Our main objective is to speed up the transactions done by customers. No manual
transactions needed generally. The second objective is to save the time which is very
important now-a-days.
It will include other objectives such as :
 To render accurate services to customer.
 The reduction of fraudulent activities
 To achieve speedy processing of customer data
 To reduce error processing, the guarantee of increase security

2. System Requirements:
2.2. Hardware Requirements:
 Processor :- Intel Pentium 4 or Later or Compatible
 Hard Disk :- 410GB or more
 RAM :- 1GB or more
 Printer :- Any
 Monitor :- SVGA Color Monitor (Touch Screen or Simple)
 Pointing Device :- Touch Pad or Keys
2.3. Software Requirements:
 Operating System :- Microsoft Windows XP or Later or Equivalent
 Front End :- Visual Basic 6.0
 Back End :- Oracle 8i

3. System Analysis :
3.2. Study of current/Existing system:
In the manual system, firstly the bank manager and its staff have to manage
information regarding the accounts and transaction of all the customers manually.
Doing this manual transaction was really tedious job. Secondly information
regarding accounts and transactions of customers were to be maintained. This
process is time consuming and it requires a great manual effort.
Disadvantages:
 More time is consumed.
 More hard work to maintain all records.
 Bulk of paper is to be searched for a single search.
3.3. Feasibility study:
3.3.1. Technical feasibility:
The system is being developed in Visual Basic 6.0. It provides comprehensive
function to make it user friendly. The data entry and report generation is also made
easy. Backup and restore of the database facility are also provided. It also provides
easy retrieval of data. The machine configuration also supports this software.
3.3.2. Social feasibility:
As this system is user friendly and flexible some problems will also be solved
which employee may be facing when using existing system. So we can say that
system is socially feasible.
3.3.3. Economical feasibility:
The cost of converting from manual system to new automatic computerized
system is not probably more. For construction of the new system, the rooms and its
facilities are available so it does not require any extra resource, only the software
requirement is there.

3.3.4. Operation feasibility:
Since the system is being in user friendly way, the new customers within a few
time can master it.
3.4. Design of new proposed system (UML):
This system provides paperless maintenance. Initially a cashier or an clerk can be
appointed to do all the transaction and update and maintain records. In the new system
the customer himself can do all the transaction and the computerized system
automatically updates and maintains the records.
Advantages:
 Less effort to complete transaction.
 Less time required.
 No need to maintain the bulk of papers.
