A framework for micropayment evaluation

Lacking payment systems become a bottleneck for the vision of the Information Economy. In many cases, the payments of a fraction of a cent, the so-called micropayments, are of particular interest. In this paper we propose a framework to evaluate the payment systems. The framework consists of a well structured parameter vector of the desired attributes. For the evaluation of attribute values, we suggest to use VTS diagrams from object-oriented analysis and design. The framework is applied to DigiCash, SET and First Virtual.
