A surfbar is a website on which a user is automatically shown advertisements and in return receives money for each period.
Two surfbars can be started via the Startpakt [1] platform by the two providers eBesucher [2] and Shimly [3]. When a surfbar is on, advertising is automatically displayed and for each advertisement displayed, the user receives a fee from both the Startpakt and one of the surfbars. If then a user has installed an addon of Surfe.be [4] in his browser, then that user receives a third passive income.
