Interoperable Mobile Payment - A Requirements-Based Architecture

Existing payment methods like cash and debit/credit card payments are still predominant in our daily lives. Nevertheless, these methods are not well suited for new payment scenarios as for example e-commerce and TV shopping, resulting in increased fraud and high disputes handling costs. Next-generation payment methods must meet technical, user, and business requirements that cover traditional as well as recent scenarios. This paper presents a mobile payment architecture that combines the security and strong user authentication of GSM networks, the cost efficiency of micropayment, and the flexibility and world wide acceptance of existing macropayment schemes.
