In this paper, we propose an Internet payment system which uses a payment gateway to handle the credit card payment transaction between customers, merchants and banks. To test and evaluate the payment system, we build an online travel agency called E-Travel, which simulates a real-life E-Payment application.
On-line travel services including flight reservation, selling of travel accessories, tour guides, and hotel reservation are provided in E-Travel. E-Travel makes use of the proposed payment system to handle the payments transferred between customers and merchants. We implement the payment model as well as E-Travel, and conduct performance evaluation on the payment system. The performance results show that our payment system is easy-to-use, secure, and cost-effective.
