Method and System for Supplying Visually Encoded Image Data

A method for supplying visually encoded image data for displaying through a mobile end device includes supplying a datum. A device type of the end device is ascertained on the basis of a user identity which is assigned to a security element integrated into the end device. On the basis of the device type of the end device, the device properties of the end device are ascertained which influence a displaying of visually encoded image data on the end device. On the basis of the ascertained device properties, an image data representation information item is generated for generating visually encoded image data for the end device in device-specific fashion. Finally, the visually encoded image data are generated based on the image data representation information item in device-specific fashion for representing the datum on the end device.
