Le téléphone portable va au-delà de ses fonctions premières de communication en intégrant des fonctions de paiement. Cette thèse propose une analyse économique des principaux enjeux du paiement mobile ; elle tente d’expliquer les causes de retard de cette technologie, ses difficultés d’émergence, d’envisager certaines pistes à même de modifier les trajectoires. Tout d’abord la technologie doit se stabiliser, offrir un service unique et interopérable pour tenter de faire émerger un réseau d’utilisateurs suffisant. L’analyse de l’environnement juridico-financier du m-paiement, technologie à mi-chemin entre la téléphonie et l’activité bancaire, a été nécessaire. La suite de la thèse est consacrée à une analyse orientée d’abord vers le consommateur puis évolue vers une analyse des relations entre fournisseurs de service. Un chapitre est consacré à l’élaboration d’un modèle empirique analysant les motifs et modalités d’adoption des utilisateurs, en fonction de la forme de la technologie mais aussi en fonction de l’usage de cette technologie. Enfin, les deux derniers chapitres sont consacrés à la modélisation des relations possibles entre fournisseurs de service. Ces deux chapitres présentent plusieurs modèles permettant de comprendre les atouts multiples mais aussi les limites du paiement mobile dans un environnement bancarisé. Ils proposent aussi un scenario explicatif du succès des solutions de m-paiement en pays émergent. Ils mettent ainsi en évidence l’intérêt du point de vue de la bancarisation de ces zones, de la présence d’offres coopératives mais surtout et paradoxalement de solutions simplifiées gérées par les opérateurs seuls. / Mobile phone overtakes its first communication functions including payment functions. This thesis proposes an economic analysis of the key issues of mobile payment, it attempts to explain the reasons of the delay and its difficulties to emerge. First technology must stabilize, offer a unique and interoperable service to try to bring out a sufficient network of users. The analysis of the legal and financial environment of m-payment technology halfway between telephony and banking was necessary. The rest of the thesis is devoted to an analysis oriented to consumer then progresses to an analysis of the relationship between service providers analysis. A chapter is devoted to the development of an empirical model analyzing the reasons and conditions of user's adoption. Finally, the last two chapters are devoted to the modeling of possible relationships between service providers. These two chapters have several models to understand the many advantages but also the limitations of the mobile payment in a banked environment. They also offer an explanatory scenario to the success of m- payment solutions in emerging countries. And they highlight the interest from the point of view of banking services in these areas, the presence of co-offers, but especially and paradoxically solutions managed by operators.

The financial services industry is one of the most rapidly growing industries worldwide. Although mobile payment (m-payment) systems have generated a lot of hype, not all supportive infrastructures are in place where one firm’s service can be applied globally. Technology has provoked major changes in this industry with how firms operate and innovate as well as how they adapt their business models. Additionally, how services expand and understanding the ways new services are developed in different countries are becoming increasingly relevant. This qualitative, multidisciplinary study compares the sectoral system of innovation (SSI) and service innovation of m-payment systems between a developed country, the United Kingdom (UK), and a developing country, India. The dissertation draws upon 27 original interviews in the UK and India in order to analyse and identify the drivers of innovation. The analytical framework is designed for a firm-level analysis where variables affecting the resources and capabilities act as a way of integrating knowledge and influencing the innovation process. The main research questions are: how does a diverse SSI shape business models within the m-payment systems; why and to what extent do the processes of service innovation differ between m-payment systems as explained in the UK and India? The SSI approach links innovation to the interactions of the different actors in the economy and the system. Innovation is either the process of creating or the recombining of knowledge for some new use to become an outcome of that process. Innovation does not sit within the boundaries of an organization nor does it sit neatly at one level, but instead it is a multifaceted construct. Thirteen case studies are employed with the main industries being banking, telecommunications and technology. A thematic analysis is applied in using an inductive, exploratory approach from an interpretive perspective. The outcomes of interpretism are helpful in presenting an understanding of the causal mechanisms of innovation through a theoretical framework of resource-based view (RBV) and knowledge-based view (KBV). Findings from the research will show a lack of an all-encompassing and exhaustive perspective of m-payment systems. A hindrance of innovation has caused a fundamental problem identified in the UK showcasing a lack of strong innovative, specific institutions; while in India, poorly managed implementation of institutions has led to strengthening of cognitive institutions amongst firms. In particular, innovation in emerging fields that have yet to reach their technological maturity is just as strong in developing countries as compared to developed countries. Furthermore, innovation happens in developing countries through processes that are more complex than originally conceptualized. The contribution to the theoretical understanding of innovation is two-fold. Firstly, in researching mobile financial systems in a developed and developing country, an m-financial SSI framework is constructed that is usable by policy-makers, analysts and firms exploring their value chain positioning. Secondly, the research emphasises the importance of integrating firms’ activity (including new product and service design) into integrated service systems since the particular nature of these systems for m-payments varies between contexts. Therefore, the research helps to show how m-payment systems vary and in particular what are the drivers of innovation between a developed and developing context. Thus, existing theory needs to take into consideration the possibility that emerging market firms are perhaps more innovative than developed countries, and as a consequence, future research should address this with caution. For management practice, the research has shown that there is still not a complete model in explaining the performance of firm level innovation. For practitioners, innovation and technological development needs to get better at interoperability with users and merchants. Furthermore, business models will need to evolve from limited proprietary solutions towards cooperation and standardised solutions if there are to be successful, global firms.

Avec l’émergence de la technologie en champ proche (NFC), le terminal mobile est devenu un véritable instrument de paiement sans contact. Ce type de système constitue une nouvelle opportunité pour relancer les systèmes de paiement électronique (SPE) destinés aux micropaiements. L’objectif de cette recherche est de développer un modèle et des instruments de mesure permettant d’appréhender et de cerner les facteurs influençant l’acceptation de ces systèmes. En se basant sur les paradigmes de l’acceptation des technologies et les travaux de recherche autour des SPE, nous avons développé un modèle conceptuel qui intègre à la fois la TUAUT et l’ATT. Notre modèle permet à la fois de tenir compte des stratégies d’adoption des individus et de leur intention d’adoption. En effet, l’utilité perçue, la facilité d’utilisation perçue et les conditions facilitatrices ne sont plus suffisantes pour qu’une technologie soit adoptée. Il faut désormais que les caractéristiques de cette technologie conviennent et répondent aux caractéristiques et aux exigences de la tâche qu’elle va supporter. Nos résultats ont été mesurés et validés à l’aide d’une analyse par équations structurelles des données collectées auprès d’un échantillon de 629 individus / With the emergence of near-field technology (NFC), mobile terminal have become a true instrument of contactless payment. This type of system is a new opportunity to boost the electronic payment systems (EPS) for the micropayment. The objective of this research is to develop a model and measurement tools to handle and to identify factors influencing the acceptance of these systems. Based on the paradigms of the acceptance of technology and research around the SPE, we have developed a conceptual model which integrates the UTAUT and TTF. This model allows both to consider the adoption strategies of individuals and their intention to adopt. Indeed, perceived usefulness, perceived ease of use and facilitating conditions are no longer sufficient for a technology to be adopted. The capabilities of this technology have to match the tasks that the user will perform. Our result have been measured and validated thanks to structural equations analysis of data collected from a sample of 629 individuals

The thesis is aimed to propose a financial innovation called COCONUT payment system. This innovative payment system is based on a combination of the cash and electronic money, presented as an ATM-like machine for purchase and payment execution, and operated via an electronic account, which allows its users to operate as a credit cards owner. This study commences with a review of the current major payment systems in the United States, followed by an analysis of the strength and weakness of these systems, and then proposes a payment system that combines the most popular two: cash and credit card with a healthier mechanism on financial control to both avoid the recurrence of financial crisis caused by credit crush and keep the current benefits. The COCOCNUT system can be applied not onbly to the market of the USA, but BRIC, developing and under seveloped countries’ market, those regions where cash remains the major payment way. As for the feasibility and the probability of promoting and applying this new system to replace the current systems or to implement in the new markets, the proposed COCONUT payment system, takes into consideration the differences of markets and regional regulations. The COCONUT project also provides trial calculations of its value proposition from the perspective of the project realization.

<p>I ett kortbetalningssystem såsom Visa International Service Association (Visa) finns det fem stycken tongivande parter: kortinlösaren; kortutgivaren; kortinnehavaren; säljföretaget och Payment Service Provider (PSP). Ett säljföretag som låter sina kunder betala för varor och tjänster på sin webbplats skickar kundernas kortnummer krypterat till en PSP som vidarebefodrar dessa till VisaNet som är dataknutpunkten i Visa. VisaNet söker med hjälp utav kortnumret upp den bank som har utgivit kortet och efterfrågar samma bank om en transaktion får ske från kortet. VisaNet får ett svar som vidarebefordras vidare tillbaka till säljföretaget som sedermera även får sina pengar överförda till sitt konto från kundens konto.</p><p>Uppdragsgivaren till detta examensarbete skall utveckla ett helt eget system och bli sin egen PSP utifall uppdragsgivaren beräknar att mer än 1,3 miljoner stycken kortbetalningar kommer att ske genom uppdragsgivarens kortbetalningssystem per år. När detta examensarbete utfördes uppskattades antalet kortbetalningar per år inte till denna siffra och rapportförfattaren utvecklade därför ett korbetalningssystem med hjälp utav en befintlig PSP.</p><p>Kortbetalningssystemets kärna är ett API som andra systemutvecklare hos uppdragsgivaren kan anropa. API:t har ett antal funktioner såsom att utföra en kortbetalning, reservera en kortbetalning eller att avbryta en reserverad kortbetalning. Rapportförfattaren har även utvecklat ett grafiskt övervaknings- och administrationsgränssnitt för att kunna övervaka de kortbetalningar som sker samt enkelt kunna felsöka fel som uppstår i systemet.</p>

An online payment system allows a customer to make a payment to an online merchant or a service provider. Payment gateways, a channel between customers and payment processors, use various security tools to secure a customer’s payment information, usually debit or credit card information, during an online payment. However, the security provided by a payment gateway cannot completely protect a customer’s payment information when a merchant also has the ability to obtain the payment information in some form. Furthermore, not all merchants provide a secure payment environment to their customers and, despite having a standard payment policy, adhere to it. Consequently, this exposes a customer’s payment information to risks of being compromised or misused by merchants or stolen by hackers and spammers. In this thesis we propose a new approach to payment systems in which a customer’s payment information cannot be obtained by a merchant. A customer sends his payment information directly to a payment gateway and a payment gateway, upon verifying the transaction, sends a payment to the appropriate merchant. We use the Pedersen commitment scheme along with dual signatures to securely transfer funds to a merchant and protect a customer’s payment information from any Internet vulnerabilities.

61 Abstract The Financial Arbitrator was established on the basis of European legislation to handle consumer's disputes on the financial market fast, efficiently and free. This thesis mainly focuses on its role in payment system sector with regards to new Act on payments and was divided into three main chapters. The chapter one aims at the development of legal regulations in last fifteen years in the Czech republic and explores grounds of separation from the Czech National Bank to establish the independent institution. Handling disputes may even result into achieving an amicable settlement, albeit its natural character does not meet the requirements of Administrative Code resulting as more informal resolution. The range of clients solely entitled to submit a claim was in recent years strictly restricted to consumers although competencies of Financial Arbitrator were extended. The author also analyses rules of the proceedings and educational activities of the Financial Arbitrator to lift financial awareness of consumers. The chapter two describes individual financial services and persons authorized to provide payment services in order to specify competencies of Financial Arbitrator since the law authorizes the Financial Arbitrator to decide disputes between the consumer and payments service provider arisen...
