Electronic-Onboard-Ticketing: Software Challenges of an State-of-the-Art M-Commerce Application

In this paper we present E-ON (Electronic-Onboard-Ticketing). E-ON is an innovative m-commerce application using state-of-the-art technology. E-ON is a location-based service that enables a customer to purchase railway tickets directly on the train. A Personal Digital Assistant (PDA) implements the user interface. The connection between the customer's PDA and the service is established using Bluetooth, a new short-range communication technique. All parts of the application are programmed in Java.
