With mobile payment, individuals can buy goods and services through the use of a mobile device and wireless technology. Still, although the usage of mobile payment provides several advantages, such as a more convenient and faster paying-process, it is hardly used. Individuals rather stick with their current payment method, such as cash, EC card or credit card. In this study, we therefore try to...

Vertical restrictions have theoretically ambiguous efficiency effects. Marketplace evidence is therefore required to reveal the presence of anti-competitive foreclosure. The bundling of mobile phones with cellular network service offers one such market test. Two European nations—Finland and Belgium—prohibited tying arrangements for mobile service and mobile devices (handsets) in wireless broadb...

A typical shopping scenario nowadays is that shoppers browse and try the products offline and then buy them online from a competing retailer. This phenomenon commonly described as “showrooming” occurs because of the ubiquity of mobile devices and the ease of switching between multiple retail channels. The presence of these mobile-assisted shoppers in a multichannel retailing environment is a se...

Unlike other technologies, the telephone is unusual in that it cannot be 'turned off'. Almost uniquely, its design does not incorporate an off switch, or when it does, it tends to be located in an inaccessible position (such as on the underside of the phone). Rather than arguing that this is a special feature of telephones, this paper argues that this is an example of designers seeing rules as ...

One common mobile robot design consists of three ‘omniwheels’ arranged at the vertices of an equilateral triangle, with wheel axles aligned with the rays from the center of the triangle to each wheel. Omniwheels, like standard wheels, are driven by the motors in a direction perpendicular to the wheel axle, but unlike standard wheels, can slip in a direction parallel to the axle. Unlike a steere...
