Cybermoney in the Internet: An Overview over new Payment Systems in the Internet

Part of the IFIP Advances in Information and Communication Technology book series (IFIPAICT)


This article gives an overview over some of the most promising electronic payment systems: iKP, SET (as harmonization of Mastercard-SEPP and VISA-STT), Express, First Virtual, CyberCash, Ecash, CAFE, Mondex, Ravensburg’s GeldKarte. We describe their technical and application aspects. We highlight the role of smartcards for their usage and their applicability for the Internet.

As an introduction to the overview, we present some theoretical considerations on digital money. We formulate critical requirements for digital money and how money can appropriately be expressed by digital means. We also discuss the problem of fair exchange of money versus goods.
