Banks supply payment services that underpin the smooth operation of the economy. To ensure an effi cient payment system, it is important to maintain competition among payment service providers, but data available to gauge the degree of competition are quite limited. We propose and implement a frontierbased method to assess relative competition in bank-provided payment services. Billion dollar b...

We model the introduction of a new payment method that competes with an existing payment method. Due to network adoption effects, there are two symmetric pure strategy equilibria in which only one of the two payment methods is used. The equilibrium where only the new payment method is used is socially optimal. In an experiment, we find that, depending on the fixed fee for acceptance of the new ...

In daily life, ordinary cash is more and more replaced by electronic means of payment. Where on the one hand side macro payment systems are well covered by credit cards, micro payment systems still suffer from different technological and usability issues. Besides usability, security in payment systems has always been a hot topic ever since. In this paper we present a new, promising approach for...

The Internet Open Trading Protocol (IOTP) is an electronic commerce protocol being developed by the Internet Engineering Task Force. IOTP aims at providing an interoperable framework for electronic commerce (ecommerce) over the Internet. IOTP is expected to evolve into one of the central building blocks for the developing of next generation e-commerce on the Internet. The success of electronic ...

As from the beginning of the late 70's an impressive number of innovative electronic payment systems have been developed and tested commercially. However, the resulting variety and complexity of the systems have turned out to be one of the obstacles for the broad acceptance of electronic payment. In this paper we propose a process and service oriented framework, which offers a structural and co...

Simulations are among the analytical tools in payment systems analysis. They can be used to overcome epistemological weaknesses of models and calibrations, and they are virtual experiments that do not affect the real performance of payment systems. The chapter is intended to give an inside view into the use of simulations as an analysis tool for payment systems as well as settlement systems. Se...

Success in online services cannot promise the success in corresponding mobile services. To understand the mobile service adoption behavior under the context of online service transition, this study, taking mobile payment as an example, from a trust transfer perspective, examines users’ acceptance of mobile payment using the TAM (Technology acceptance model). A field survey with 220 mobile payme...

Mobile payment normally occurs as a wireless transaction of monetary value and includes the initiation, authorization and the realization of the payment. Such transactions are facilitated by purpose-built mobile payment systems that are part of the service infrastructure supporting the functioning of mobile business applications. A number of stakeholder groups may be involved in concluding a mo...

Merchants are competing to offer the use of mobile payment to encourage shopping. many mobile payment systems were made available in various locations worldwide; however, they have various drawbacks. This paper proposes a new mobile payment system that discusses the main drawbacks of these systems, namely security and speed of transaction. The proposal is featured by being simple to use by cust...

Fair payment protocol is designed to guarantee fairness in electronic purchasing, that is, no party can falsely deny involvement in the transaction or having sent/received the specific items/payment. In this paper we first present an efficient fair payment protocol providing invisibility of TTP, timeliness, and standard RSA signatures as the final non-repudiation evidences. Then we present a se...
