  • An Overview of Today's and Tomorrow's M- Commerce In
    AN OVERVIEW OF TODAY’S AND TOMORROW’S M- COMMERCE IN THE NETHERLANDS AND EUROPE Hong-Vu Dang BMI Paper AN OVERVIEW OF TODAY’S AND TOMORROW’S M- COMMERCE IN THE NETHERLANDS AND EUROPE Hong-Vu Dang BMI Paper Vrije Universiteit Amsterdam Faculty of Sciences Business Mathematics and Informatics De Boelelaan 1081a 1081 HV Amsterdam www.few.vu.nl August 2006 PREFACE A part of the masters programme of the study that I am following, Business Mathematics & Informatics (BMI) at the Vrije Universiteit Amsterdam, is writing a BMI paper. In this paper a problem in the field of BMI is assessed using existing literature. The subjects addressed in this paper are the past, present and future developments of the relatively new phenomenon called m-commerce. Developments discussed will be from a technological perspective as well as a business perspective. I would like to express my gratitude to Dr. S. Bhulai of the Vrije Universiteit Amsterdam for his guidance while I was writing this paper. Hong-Vu Dang BMI paper: An Overview Of Today’s And Tomorrow’s M-Commerce In The Netherlands And Europe ABSTRACT This paper explains: • What m-commerce is: in a nutshell, it is commerce using a mobile device such as a hand-held device or a smart phone; • What it is used for: currently, m-commerce in Europe mainly consists of messaging, such as SMS, and mobile entertainment (think of ringtones, wallpapers, and mobile games); • What technology is involved with m-commerce: this paper describes the history and future of mobile networks from 1G to 3G, and how other technologies can be used for m-commerce such as GPS, and Wi-Fi; • The business aspects of m-commerce: how much does it cost to enable m- commerce (for instance the costs of the European UMTS network) and how much turnover is made.

Introduction If you are familiar with the telco industry you know how to spell its favorite four letter word: ARPU, Average Revenue Per User. ARPU is a measure of monthly revenue divided by the total number of end-user customers. When ARPU is high, it means the telco has better customers-- those that use lots of high margin services. When ARPU is low, the telco likely has the same fixed costs per user, and lower overall margin. In the minds of most telecom executives, ARPU going up is good, ARPU going down is bad. In this whitepaper we will review how and why telcos can and should play a stronger role in the identity industry. We will also provide a financial model for how various aspects of identity management can contribute to ARPU. Additionally, we will highlight some of the challenges facing the identity industry as a whole and some of the issues telcos will have to face as they navigate their way through the identity ecosystem. As a backdrop to this discussion, it’s important to start with the fact that mobile phones are rapidly reaching global ubiquity.
