Abstract:
Needs arises today for the new electronic payments means especially in big cities to pay daily transactions and services bills like: telecom, electricity, water, medical care and education through a fast and easy ways such as Internet. Services providers, vendors, and consumers are looking for credit card payments on the Internet as one possible alternative. This on-line payment processing using a third party is not suitable for the developing countries in most of the cases because of the lack of the infrastructure needed and excessive costs associated with it. As a remedy of this problem, this thesis proposes a model for an easy security incorporation in credit card based electronic payment system using Internet with the minimum involvement of an on-line third party processor; which tends to be low cost, easily integrated to the existing systems, and fits for the developing countries.
Due to the lack of international credit cards in Sudan because of the economical sanction, the thesis can apply this proposal in a model called: "Trade Points Oriented e-Payments System (TPOPS) for Sudan". It is designed and developed as a web application that fits Sudan and utilizes the current infrastructure. These points should be connected to the banking network which controlled and overseen by the central bank of Sudan.
TPOPS model is applicable and has many basic features to be evaluated based on them:
Anonymity: Transaction parties does not need to know each other.
Traceability: By saving these transactions with both consumers and vendors.
Secured Transactions: Using the public key infrastructure technology.
Flexibility and Interoperability: Using web Services technologies.
The implemented model has a weakness point that , it is not connected to the mobile network even it’s spreading and fast growing, and for future still more work and researches are needed to look for: the security measures and standards, regulations and legislation, and the business acceptance issues.
