Title of the Project: Mobile Banking.

Problem Definition:Mobile Banking refers to provision of banking- and

financial services with the help of mobile telecommunication devices. The scope of offered services may include facilities to conduct bank transactions, to administer

accounts and to access customized information.

Why this Topic is chosen:Mobile devices, especially smart phones, are the most

promising way to reach the masses and to create “stickiness” among current customers,

due to their ability to provide services anytime, anywhere, high rate of penetration and

potential to grow. Mobile users have just started to fully utilize the data capabilities intheir mobile phones. In Asian countries like India, China, Indonesia and Philippines,

where mobile infrastructure is comparatively better than the fixed-line infrastructure, and

in European countries, where mobile phone penetration is very high (at least 80% of consumers use a mobile phone), mobile banking is likely to appeal even more.

Concepts: Java Technology (J2ME and J2EE)

Objective:

• Customer Service provision so as to make it easier for him to check his

basic account information.

• Anytime, anywhere facility to access his bank account information.

Scope:

Mobile Web applications enable users on the move to access date on their handheld devices. The various applications built in the project are as follows: Check Balance,

Check status, Fund transfer, Loan status, Locker status and Deposit Details.

Due to it’s Anytime, Anywhere, And Anyplace offerings customers will be able

to access their bank accounts when and wherever they want thus saving their time and

money. They would not be required to travel to the location of their account and carry outtransaction there instead all the banking transactions will be carried out on the mobile

handset itself. This facility is now limited to a particular branch or a particular bank but

in future it can be used to implement banking transactions over accounts belonging to

different banks. The project will be a global success if all the security issues are properly

taken care of and tested for its wide range functionality and implemented accordingly.

Functions:

• Take user information through a jar file loaded on his cell phone.

• Activated General Packet Radio Service (GPRS) connection will allow theuser to send request to the Web server.

2



• Web Server responses by processing the servlet which retrieves

information from the database for the user .

Constraints:

• The user should have a cellphone which connects to the internet.

• The user should have java enabled cellphone.

Methodology:

From the User End:

• The user is provided with a jar file. On opening the jar file, he has to login

to his account with his corresponding password.

• The GPRS being activated will allow the user verification.

• The user queries for various bank details through this jar file.

• He is responded with corresponding replies.

From the Service Providers End:

• The user requests for logging in. After verification he is allowed, else not

allowed to access.

• The user requests for other data. Server process the request by processing

the servlet which gets the corresponding information.

• This response is then sent to the user .

Hardware Requirements:

• Pentium 3- 800 MHZ• 256 MB RAM

• GPRS enabled mobile phones

Software Requirements:

• Tomcat server

• Java Wireless toolkit

• Windows Operating System

• Ms-Access

The contribution of the project: Can be enhanced more with security features and implemented at real-time for

various Banks and finance services.

Basic concept and its origin:

Banking:

A banker or bank is a financial institution that acts as a payment agent for

customers, and borrows and lends money. Banks act as payment agents by conducting

checking or current accounts for customers, paying Cheque drawn by customers on the

bank, and collecting Cheque deposited to customers' current accounts. Banks also enablecustomer payments via other payment methods such as telegraphic transfer and ATM.

Banks borrow money by accepting funds deposited on current account, accepting term

deposits and by issuing debt securities such as banknotes and bonds. Banks lend money

by making advances to customers on current account, by making installment loans, and by investing in marketable debt securities and other forms of lending.

Banks provide almost all payment services, and a bank account is considered

indispensable by most businesses, individuals and governments.

Banks offer many different channels to access their banking and other services:

• A branch, banking centre or financial centre is a retail location where a bank or financial institution offers a wide array of face to face service to its customers

• ATM is a computerized telecommunications device that provides a financial

institution's customers a method of financial transactions in a public space withoutthe need for a human clerk or bank teller. Most banks now have more ATMs than

branches, and ATMs are providing a wider range of services to a wider range of

users. For example in Hong Kong, most ATMs enable anyone to deposit cash toany customer of the bank's account by feeding in the notes and entering the

account number to be credited. Also, most ATMs enable card holders from other

banks to get their account balance and withdraw cash, even if the card is issued bya foreign bank.

• Mail is part of the postal system which itself is a system wherein written

documents typically enclosed in envelopes, and also small packages containing

other matter, are delivered to destinations around the world. This can be used todeposit Cheque and to send orders to the bank to pay money to third parties.

Banks also normally use mail to deliver periodic account statements to customers.

5



• Telephone banking is a service provided by a financial institution which allows its

customers to perform transactions over the telephone. This normally includes bill

payments for bills from major bill payers. (E.g. for electricity).

• Online banking is a term used for performing transactions, payments etc. over the

Internet through a bank, credit union or building society's secure website.

Online Banking:

Online banking (or Internet banking) allows customers to conduct financial

transactions on a secure website operated by their retail or virtual bank, credit union or

building society. Online banking solutions have many features and capabilities incommon, but traditionally also have some that are application specific.

The common features fall broadly into several categories

• Transactional (e.g., performing a financial transaction such as an account to

account transfer, paying a bill, wire transfer... and applications... apply for a loan,new account, etc.)

o Electronic bill presentment and payment - EBPP

o Funds transfer between a customer's own checking and savings accounts,

or to another customer's account

o Investment purchase or sale

o Loan applications and transactions, such as repayments

• Non-transactional (e.g., online statements, check links, co browsing, chat)o Bank statements

• Financial Institution Administration - features allowing the financial institution to

manage the online experience of their end users

• ASP/Hosting Administration - features allowing the hosting company to

administer the solution across financial institutions

Features commonly unique to business banking include

• Support of multiple users having varying levels of authority

• Transaction approval process• Wire transfer

Features commonly unique to Internet banking include

• Personal financial management support, such as importing data into a personal

finance program such as Quicken, Microsoft Money or TurboTax. Some online banking platforms support account aggregation to allow the customers to monitor

6



all of their accounts in one place whether they are with their main bank or with

other institutions...

Mobile Web:

The Mobile Web refers to the World Wide Web as accessed from mobile devices

such as cell phones, PDAs, and other portable gadgets connected to a public network.Access does not require a desktop computer.

However, Mobile Web access today still suffers from interoperability and usability

problems. This is partly due to the small physical size of the screens of mobile devices

and partly due to the incompatibility of many mobile devices with not only computer operating systems, but also the format of much of the information available on the

Internet.

New tools such as Macromedia's Flash Lite or Sun's J2ME enable the production of

user interfaces customized for mobile devices.

GPRS:

GPRS can be used for services such as Wireless Application Protocol (WAP)access, Short Message Service (SMS), Multimedia Messaging Service (MMS), and for

Internet communication services such as email and World Wide Web access.

WAP is just a gateway used to access Internet via mobile phone and vice-versa.

Theoretical Analysis:

The advent of the Internet has revolutionized the way the financial

services industry conducts business, empowering organizations with new businessmodels and new ways to offer 24x7 accessibility to their customers.

The ability to offer financial transactions online has also created new players in the

financial services industry, such as online banks, online brokers and wealth managers

who offer personalized services, although such players still account for a tiny percentageof the industry.

Over the last few years, the mobile and wireless market has been one of the fastest

growing markets in the world and it is still growing at a rapid pace. According to the

GSM Association and Ovum, the number of mobile subscribers exceeded 2 billion inSeptember 2005, and now exceeds 2.5 billion (of which more than 2 billion are GSM).

According to a study by financial consultancy Celent, 35% of online banking householdswill be using mobile banking by 2010, up from less than 1% today. Upwards of 70% of

bank center call volume is projected to come from mobile phones. Mobile banking willeventually allow users to make payments at the physical point of sale. "Mobile contact

less payments” will make up 10% of the contact less market by 2010.

Many believe that mobile users have just started to fully utilize the data capabilities in

their mobile phones. In Asian countries like India, China, Indonesia and Philippines,where mobile infrastructure is comparatively better than the fixed-line infrastructure, and

in European countries, where mobile phone penetration is very high (at least 80% of

consumers use a mobile phone), mobile banking is likely to appeal even more.

This opens up huge markets for financial institutions interested in offering value added

services. With mobile technology, banks can offer a wide range of services to their

customers such as doing funds transfer while traveling, receiving online updates of stock

price or even performing stock trading while being stuck in traffic. According to theGerman mobile operator Mobilcom, mobile banking will be the "killer application" for

the next generation of mobile technology.

Mobile devices, especially smartphones, are the most promising way to reach the masses

and to create “stickiness” among current customers, due to their ability to provideservices anytime, anywhere, high rate of penetration and potential to grow. According to

Gartner, shipment of smartphones is growing fast, and should top 20 million units (of over 800 million sold) in 2006 alone.

In the last 4 years, banks across the globe have invested billions of dollars to build

sophisticated internet banking capabilities. As the trend is shifting to mobile banking,

there is a challenge for CIO’s and CTO’s of these banks to decide on how to leverage

their investment in internet banking and offer mobile banking, in the shortest possibletime.

The proliferation of the 3G (third generation of wireless) and widespread implementation

expected for 2003-2007 will generate the development of more sophisticated services

such as multimedia and links to m-commerce services.

Identification of the project from the study:

Mobile Banking is a concept that was developed thinking about the fact that

8



Mobile handsets are a common commodity today and are found to be affordable to the

common man. I realized that how easy it would be to carry out banking transactions if

they were carried out from the mobile handset itself.I started the research 2 months prior to going along with the project which

involved getting acquainted with the variety of banking operations and also the working

of web and wireless operations.For my research work, I consulted various banking officials and found out what

are the various banking operations that could be implemented using the mobile handset.

I tried to find out about the practicality of the project by studying the implementations of the web and wireless applications. I did my research regarding which all sectors of

banking could be implemented using our project. Also the research involved learning

about various software’s available that could be used to implement my project and I

studied the operation of the various mobile emulators for the same.The idea that mobile phones bring economic benefits is now widely accepted. In

places with bad roads, few trains and parlous land lines, they substitute for travel, allow

price data to be distributed more quickly and easily, enable traders to reach wider markets

and generally ease the business of doing business.With mobile banking, the customer may be sitting in any part of the world (a true

anytime, anywhere banking) and hence banks need to ensure that the systems are up andrunning in a true 24 x 7 fashion.

Mobile banking will be attractive mainly to the younger, more "tech-savvy"

customer segment. A third of mobile phone users say that they may consider performing

some kind of financial transaction through their mobile phone. Most of the users areinterested in performing basic transactions such as querying for account balance and

making bill payment.

The project is an integration of Web (J2EE) and Mobile (J2ME) technology.

Hence the basic logic is to find a solution which would provide customer the basic

services from bank using these two technologies together.

J2ME:

Java Platform, Micro Edition (Java ME) provides a robust, flexible environmentfor applications running on mobile and other embedded devices—mobile phones,

personal digital assistants (PDAs), TV set-top boxes, and printers. Java ME includes

flexible user interfaces, robust security, built-in network protocols, and support for networked and offline applications that can be downloaded dynamically. Applications

based on Java ME are portable across many devices, yet leverage each device's native

capabilities.

J2EE:

Java EE is defined by its specification. As with other Java Community Process

specifications, Java EE is also considered informally to be a standard since providers

must agree to certain conformance requirements in order to declare their products as Java EE compliant ; albeit with no ISO or ECMA standard.

Java EE also features some specifications unique to Java EE for components.These include Enterprise JavaBeans, servlets, portlets (following the Java Portlet

specification), JavaServer Pages and several web service technologies. This allows

developers to create enterprise applications that are portable and scalable, and that

integrate with legacy technologies. A Java EE "application server" can handle thetransactions, security, scalability, concurrency and management of the components that

are deployed to it, meaning that the developers can concentrate more on the business

logic of the components rather than on infrastructure and integration tasks.

Description of Algorithms/Procedures/Methods/Logic:

24



Java ME has become a popular option for creating applications and games for cell

phones, as they can be emulated on a PC during the development stage and easilyuploaded to phones. This contrasts with the difficulty of developing, testing, and loading

applications and gaming for other special gaming platforms such as those made by

Nintendo, Sony, Microsoft, and others, as expensive system-specific hardware and kitsare required.

Java ME devices implement a profile. The most common of these are the Mobile

Information Device Profile aimed at mobile devices, such as cell phones, and thePersonal Profile aimed at consumer products and embedded devices like Set-top boxes

and PDAs.Profiles are subsets of configurations, of which there are currently two: the

Connected Limited Device Configuration and the Connected Device Configuration.

CLDC:

The Connected Limited Device Configuration (CLDC) defines the base set of

application programming interfaces and a virtual machine for resource-constrained

devices like mobile phones, pagers, and mainstream personal digital assistants. Whencoupled with a profile such as the Mobile Information Device Profile (MIDP), it provides

a solid Java platform for developing applications to run on devices with limited memory, processing power, and graphical capabilities.

J2ME API’s used:

• java.io :

A streamlined version of the java.io package found in the standard edition for doing Input/Output operations.

• javax.microedition.midlet

The MIDlet package defines Mobile Information Device Profile applications and

the interactions between the application and the environment in which the

application runs. An application of the Mobile Information Device Profile is aMIDlet.

The following definitions are used in the MIDlet lifecycle:

o Application management software - a part of the device's software

operating environment that manages MIDlets. It directs the MIDlet

through state changes.

o MIDlet - a MIDP application on the device. The MIDlet can signal theapplication management software about whether is it wants to run or hascompleted. A MIDlet has no knowledge of other MIDlets through the

MIDlet API.

o MIDlet States - the states a MIDlet can have are defined by the transitions

allowable through the MIDlet interface. More specific application states

are known only to the application.

25



• javax.microedition.lcdui

The UI API provides a set of features for implementation of user interfaces for

MIDP applications.

Java Platform, Enterprise Edition (Java EE) builds on the solid foundation of Java

Platform, Standard Edition (Java SE) and is the industry standard for implementing

enterprise-class service-oriented architecture (SOA) and next-generation webapplications.

26



Java Platform, Enterprise Edition (Java EE) is a set of coordinated technologies

that significantly reduces the cost and complexity of developing, deploying, and

managing multitier, server-centric applications. Building on the Java Platform, StandardEdition (Java SE), Java EE adds the capabilities that provide a complete, stable, secure,

and fast Java platform for the enterprise.

J2EE API’s used:

• javax.servlet :

The javax.servlet package contains a number of classes and interfaces thatdescribe and define the contracts between a servlet class and the runtime environment

provided for an instance of such a class by a conforming servlet container.

The Servlet API, contained in the Java package hierarchy javax.servlet,

defines the expected interactions of a Web container and a servlet. A Web container

is essentially the component of a Web server that interacts with the servlets. The Web

container is responsible for managing the lifecycle of servlets, mapping a URL to a particular servlet and ensuring that the URL requester has the correct access rights.

A Servlet is an object that receives a request and generates a response based on

that request. The basic servlet package defines Java objects to represent servletrequests and responses, as well as objects to reflect the servlets configuration

parameters and execution environment.

Lifecycle of a Servlet

The Servlet lifecycle consists of the following steps:

1. The Servlet class is loaded by the container during start-up.

2. The container calls the init() method. This method initializes the servlet andmust be called before the servlet can service any requests. In the entire life of a

servlet, the init() method is called only once.

3. After initialization, the servlet can service client-requests. Each request is serviced

in its own separate thread. The container calls the service() method of the

servlet for every request. The service() method determines the kind of request

being made and dispatches it to an appropriate method to handle the request. The

developer of the servlet must provide an implementation for these methods. If a

request for a method that is not implemented by the servlet is made, the method of the parent class is called, typically resulting in an error being returned to the

requester.

4. Finally, the container calls the destroy() method which takes the servlet out of service. The destroy()method like init() is called only once in the lifecycle of

a Servlet.

• java.sql:

27



Provides the API for accessing and processing data stored in a data source

(usually a relational database) using the Java TM programming language. This API

includes a framework whereby different drivers can be installed dynamically toaccess different data sources. Although the JDBCTM API is mainly geared to

passing SQL statements to a database, it provides for reading and writing data

from any data source with a tabular format. The reader/writer facility, availablethrough the javax.sql.RowSet group of interfaces, can be customized to use and

update data from a spread sheet, flat file, or any other tabular data source.

• java.io

Provides for system input and output through data streams, serializationand the file system. Unless otherwise noted, passing a null argument to a

constructor or method in any class or interface in this package will cause a NullPointerException to be thrown.

• java.util

Provides for system input and output through data streams, serialization

and the file system. Unless otherwise noted, passing a null argument to a

constructor or method in any class or interface in this package will cause a NullPointerException to be thrown.

30



Importance of the project:The idea that mobile phones bring economic benefits is now widely accepted. In

places with bad roads, few trains and parlous land lines, they substitute for travel, allow price data to be distributed more quickly and easily, enable traders to reach wider markets

and generally ease the business of doing business.

With mobile banking, the customer may be sitting in any part of the world (a trueanytime, anywhere banking) and hence banks need to ensure that the systems are up and

running in a true 24 x 7 fashion.
