With the increasing capabilities and the fast growing ubiquity of mobile devices in the community, the mobile market has the potential to become an important target for advertising. Today Netix AB runs the web service Skraplotto.se where users are given the opportunity to scratch tickets for free and win prises online. The prises are paid for by the advertising companies in an attempt to market their products. Recognising the growing mobile market and the potential therein, Netix has expressed interest in having a mobile version of their scratch ticket concept, Skraplotto.se, developed. This master thesis has in cooperation with Netix resulted in a ready to deploy application for Java 2 Mobile Edition (J2ME) capable mobile phones and other compatible devices, thereby allowing Netix to take their marketing concept one step further and enter into the world of mobility.
