ACKNOWLEDGEMENT

Every work requires support and contribution from different sources and people for itssuccessful completion and achieve desired outcome. We would like to thank Mr. Arun

Kumar Vaish for providing us this opportunity to work on this project as a Computer

Oriented Project.

We would like to thank him for mentoring us for this project who has guided us on every

turn throughout this project. His every suggestion was highly valued and helped us

optimize the application.

Moreover we would also like to thank the institution for providing round the clock access to

internet facilities which helped us to get relevant information. In addition to that, we wouldlike to pay heartily regards to those people who helped us directly and indirectly.

ABSTRACT

This Computer Oriented Project wishes to develop a cloud based referral system for ruralbanking customers. An Android based mobile application was developed which will be

distributed to rural customers. These customers can add their loan required on the app and

all these details will be stored in the cloud using 256 bits AES encryption. The banks can

use this data to increase their customer base.

The mobile application is built on Android Operating System, which is an open-source

operation system for mobiles. The cloud server is built on Ruby on Rails.

Another application which was built as a part of this project was Data Entry for POS

terminals, which was also an android app to update transaction details from POS terminalsto our servers.

INTRODUCTION

ANDROID

Android is a software stack for mobile devices that includes an operating system,

middleware and key applications. Android is a software platform and operating system for

mobile devices based on the Linux operating system and developed by Google and the Open

Handset Alliance.

It allows developers to write managed code in a Java-like language that utilizes Google-

developed Java libraries, but does not support programs developed in native code. The

unveiling of the Android platform on 5 November 2007 was announced with the founding

of the Open Handset Alliance, a consortium of 34 hardware, software and telecom

companies devoted to advancing open standards for mobile devices.

When released in 2008, most of the Android platform will be made available under the

Apache free-software and open-source license. Since then the market of smart phones

increased exponentially and different versions of Android platform were launched with the

Android 4.4 Kit-Kat being the latest. These versions provide enhanced support for various

features and different types of sensors, which provide a very rich experience to user and an

opportunity to developer to experiment and create amazing android apps.

RUBY ON RAILS

Ruby on Rails, often simply Rails, is anopen sourceweb application framework which runs

via theRuby programming language.It is a full-stack framework: it allows creating pages

and applications that gather information from the web server, talk to or query the database,

and render templates out of the box. As a result, Rails features a routing system that is

independent of the web server.

SOFTWARES/ RESOURCES USED

Eclipse IDE

Eclipseis anintegrated development environment (IDE). It contains a baseworkspace and

an extensibleplug-in system for customizing the environment. Written mostly inJava,

Eclipse can be used to develop applications. By means of various plug-ins, Eclipse may also

be used to develop applications in otherprogramming languages

Referral System for Rural Banking

The aim of this project is to develop a referral system for connecting the bankers to thecustomers on a rural scale.

The idea is to develop a mobile application that a volunteer would be able to use in

locations that are remote and the portability of the tablet comes in handy.

The application to be developed will be on android platforms made in such a way that

almost all android devices could run the application. The application will consist of a form

which the volunteer or the customer can fill according to their banking needs.

This information will be transferred to a database on the cloud which could then be

accessed and modified as per the need of the administrator. The data will be of importance

to the banks in the area which feel that their access to remote locations is difficult.

The project demands an application that could run on a mobile device. The application

specifications require it to be robust and run on almost all versions of android operating

system.

The application should consist of a form that the volunteer could fill in order to generate a

loan referral system database which could be later used accordingly.

The first task is to develop a front end application for the mobile. This application will be

later connected to the databse using apis written on ruby on rails.

CURRENT STATUS

The android application has been finished. The android application has the front end for the

application which will act as the contact for the volunteer for him to enter the details. It isbuilt on xml and java. The code for which is explained in the appendix.

The application opens as the form which could be changed as per the instructions of the

administrator whenever required. That form asks the user to provide details for the loan

required by the customer.

Once the user or the volunteer has entered the details and pressed the submit button, the

details fill get updated on the database using the APIs that are developed on ruby on rails.

The documentation of the APIs and the database is provided in the appendix.

The data will be stored on a MySQL database. The database is hosted on

www.p2pmicrofin.in/referral. After the application is done updating the data , it will show

the following screen to the user or volunteer so as to confirm that the operation is

successful.
