BACKGROUND OF THE STUDY
The impact of engineering age is tremendous and its arrears of application are increasing geometrically. It is believed that the information revolution will radically change the nature and quality of engineering work in the near future.
Some of the most exiting arrear of the information technology includes.
– Office automation and computer publishing
– Just-in-time (J.I.T) production techniques to reduce cost and improve quality.
– Electronic shopping and electronic funds transfer
– Computer controlled commuter train system
– Decision support system (DSS) that facilitate real time control of making under battle field condition typically characterized by uncertainty
– Computer aids to the handicapped including intelligent implants and experts for medical diagnosis.
– Computer aids instruction (CAI) and aided manufacturing.
Due to all these mentioned arrears of computer application and more, computer has now been accepted and used by so many organizations, by individuals for various purposes. It is believed that computer is an agent, which improves productivity, enhances competition.
It is however worthy to not that 75% of all computer application generate documented information. This is why it is said that had copy is the spice of information.
Computer generates printed report for adequate circulation and communication. This underlines the importance of printers in computerized operations and environments.
Considering the increasing number of which malfunction ‘vis a vis’ while the scanty availability of maintenance experts, these is no doubt that may important and urgent reports are either frustrated permanent or produced too late to serve their purpose. It therefore become very imperative to develop this EPSON printer troubleshooting and maintenance expert system which will guide a non-expert through step by step approach to troubleshoot and maintain his EPSON printer.

STATEMENT OF THE PROBLEM
When printers malfunction, it is often difficult tracing the causes of such malfunctions with respect to identified symptoms. Often, some of these faults are so minor that virtually every user is supposed to be able to handle them effectively without having to undergo the rigours of finding maintenance experts. In many occasions, the defects are perfectly eliminated by clearing the edge connectors and resisting the plugs and printer interface cards. Some diagnostic software such as Qapuls could also help in locating the causes of the problem.
However, the ne

INTRODUCTION
The latest development in business activities calls for easy access to the location of companies and their clients/ customers so that effective transaction will be achieved. Also locations and other information about school and supermarkets are needed to be known in the city.
If the information about schools and supermarket within Enugu city are known, the there will be an effective transaction of business and information will flow easily among the company’s for instance if NNPC companies is dealing on a particular material with another enterprisers within the same location that transaction of business will be very effective because they will be get thing and giving information to each other especially when there is any change in business world. More so, if a customer of a particular company wants to get any information about another company without going to the company, it does so by going through there system in the office. So, with the information now it does not need to be looking the company since he has known the location

Again, a company has to have the names of their client/ customers with their addresses and phone number register in their system so that if they want to get an information pertaining to a particular person, they do not have to start searching through a large number of complementary cards or files.

1.1 STATEMENT OF THE PROBLEM
The project is proposed to address the issue of solving the problem of directory transactions among the business premises, which usually causes a greater delay by using large number of complementary cards and letter within Enugu city. So in this case, the computer is

INTRODUCTION
1.0 BACKGROUND OF THE STUDY
Man out his initiatives, has some through series of stages inventing what are known as modern electronics (digital) computer.
Moreover, the use of microcomputers is now replacing the use of maintains and microcomputers in may fields of endeavors, especially business oriented and commercial applications. This can be attributed to the fact that they are easier to use and considerably cheaper than mini and mantrame computers. The development however, necessitates that there should be a form of protection for data held on these microcomputers against accidental or intentional destruction, modification or disclosure.
Specially, the microcomputer hard ware and software facilities should be protected against unauthorized use. An individual/owing of a computer system has the right to protect and monitor the use of the resources on his system. Without the security, of data on computer facilities, users would face a lot of problem both operation and social.

1.1 THE STATEMENT OF THE PROBLEM
There is this need for the resources of microcomputer system to be effectively, judiciously and efficiently utilized, not only that, it is also necessary to monitor who uses a particular system and how much such a user is to pay for services obtained, that is, there should be system security and proper job accounting.
The absence of security for computer system can result in a number of threats to the organization or to information user, such as, non availability of information to those who need them or alternatively the provision of information to those who should not have it. The design of an effective system security procedure would enable prevention, which is the task of trying to stop instances of misuses or failures from happening in the first place e.g ensure that unauthorized users are able to gain access an information system or protecting valuable data.

1.1.1 THE SUB PROBLEM
Absolute security cannot be achieved but must continuously be sought. The nullity is that as long as computer systems are utilized, there will continue to be the opportunity for accidental of deliberate failure. The primary goal of security system (prevention) is an ideal that simply cannot be achieved in all instances. Therefore, the best is to make some limited degree of prevention. Unfortunately, the method and degree that may be applied to minimize threats will themselves be constrained according to the perceived threats and costs of preventing the identified threats.

1.0 INTRODUCTION
The traditional management as well as organizational behaviour and operation research theories agrees that the organization provides the system and decision centers for decision-making.
Information as a data has been transformed through some process either (mechanical, electronic, mathematical or human) into an information system, with the view of achieving a good.
Information system in many organizations has various definitions due to several discipline, but in this research work, information system is defined as it relates for a small business enterprise. It all involves the flow of data within the organization for effective decision making. The neglect of a business enterprise information system due to economic constraints poses a lot of problem. Business enterprise information system comprises of sub-system which includes purchase system, management a well as planning system.
Furthermore, business enterprise of information is categorized into business and policy. The budgets and capital investment analysis are financial information whereas information generated from processing of transaction data are of accounting.

1.1 BACKGROUND
In the early days, before the advert of the Europeans, the people in Nigeria were engaged in various kinds of occupations which were greatly determined by factors such as geographical location, nature of the land and the cultural background of the community.
People living along the reverine area engaged in fishing and net making, others hunted, made clothes and built different kinds of shelters, while people with vast areas of arable land farmed and produced both food and cash crops. Still others engaged in creative activities such as carving, metal work and black smiting. People specialized in their various areas of endeavours and exchanged their products with one another. Trading them was by barter whereby goods were exchanged with goods. For example, a farmer gives a shoemaker twenty tubers of yarm for one pair of shoes, a fat goat for a pair of trousers, this was called barter system. It had a lot of inherent problems.

1.2 OBJECTIVE OF THE PROJECT
The objectives of the project work cannot be over emphasized. Objectives of an enterprise information ranges from

DESIGN AND IMPLEMENTATION OF AN ONLINE MEMBERSHIP REGISTRATION AND PAYMENT SYSTEM

Abstract

The adoption of online payment system by commercial enterprise has been in existence since the mid 90s, much greater in number due to lower operating costs associated with it. Electronic banking has been in the form of automatic teller machines and telephone transactions. More recently, it has been transformed by the Internet, a new delivery channel for banking services that benefits both customers and banks. Access is fast, convenient, and available around the clock. Furthermore, customer’s application for electronic banking facilities is expanding as the cost savings on transactions over the internet are significant. The chances and threats that the internet symbolizes is no longer news to the present day banking sector. No traditional bank would dare face investment analysts without an Internet strategy. Moreover, business success is not guaranteed by a detailed and thoughtful approach to the internet. The main intention behind the commencement of electronic banking services is to provide the customers with an alternative that is more responsive and with less expensive options. With options just a click away, customers have more control than ever. Their expectations are usability and real-time answers. They also want personal attention and highly customized products and services. This research intends to see how e-commerce and internet banking has improved the efficiency and effectiveness in the bank, take a look at the security measures on ground and also proffer a solution that can eradicate fraud in internet banking.

1.0       INTRODUCTION

• Background of the Study

Banks have traditionally been in the forefront of harnessing technology to improve their products and services. They have over the time been using electronic and telecommunication networks for delivering a wide range of value added products and services. The range of services and products offered by different banks vary widely both in their contents and sophistication. E-banking provides enormous benefits to consumers in terms of the ease and cost of transactions. However, it can be thought of as a service that allows customers to use some forms of computer to access account-specific information and possibly conduct transactions from a remote location – such as at home or at the workplace. The most efficient system architecture and advanced technologies are being used for E-banking results for the provision of internet banking services for the financial sector which enables the banks to carry out the their services like web banking to their customers. While over the years developed countries like Sweden have not tapped into the freedom to conduct routine banking transactions from the comfort and security of customer. Electronic banking has been around for some time in the form of automatic teller machine and telephone transactions. “More recently, it has been transformed by the Internet, a new delivery channel for banking services that benefits both customer and bank. Access is fast, convenient, and available round the clock, whatever the customer’s location. Plus, banks can provide services more efficiently and at substantially lower costs”. E-banking also makes it easier for customer to banks’ services and products, can increase completion among banks, and allows banks to penetrate new markets and thus expand their geographical reach. Some even see electronic banking as an opportunity for countries with underdeveloped financial systems to leapfrog developmental stages. Customer in such countries can access services more easily from banks outside his/her own country through wireless communication systems, which are developing more rapidly than traditional “wired” communication networks. Probably, the major phenomenon of the twenty first century has been electronic communication and information technology. The technological progress is now sufficiently well advanced for it to enable commercial transaction and non commercial activities which is facilitated through the use of information technology and network technology such as the internet, intranet and extranet. Electronic Banking has emerged as a significant and rapidly growing component of the world economic exchange. Through Electronic Banking the world economic exchange has been reduced to a tiny global village in terms of its information capacity and the resources it holds which can be accessed by anybody from anywhere in the globe through the use of medium of E-commerce namely the internet and some other electronic devices.

Electronic Banking does not only encompass the way you shop over the Internet, but also the ways you carry out banking transactions. A few years ago, banks started to offer their service on the Internet, in addition to the traditional services in the branch. This allowed customers, more independence in the choice where and when to bank, as they were not bound to opening hours. Electronic Banking has revolutionized the way business is transacted by globalizing the business enterprise. Multinationals, small and medium scale industries no matter their geographical locations are all beneficiaries of electronic banking. It encompasses all kind of commercial transaction that is conducted on an electronic medium, mostly through the Internet.

E-banking links business to customers no matter their geographical location. It allows companies to make new business contacts from different global business alliance, test near products and services, and make market research and other enquiries all at a minimal cost both financial and otherwise.

 

• Statement of the Problem

In banking industries today, queuing has become the order of the day, customer’s line up for hours waiting to withdraw or deposit money. This creates a lot of problem to both customers as they waste their useful time in the banking hall, and also management of the bank as the run around to find solution to their problems. Also it is observed that customers cannot withdraw money any time they want as banks has their working hours. This is a big problem as needs can arise at any time and human beings will always like to have those needs solved. Also money deposited into accounts at times takes
