Method and System for Supplying Visually Encoded Image Data

A method for supplying visually encoded image data, preferably in the form of at least one bar code, for displaying through a mobile device, comprising the steps of:

• supplying a datum to be represented through the visually encoded image data;
• ascertaining a device type of the device on the basis of a user identity which is assigned to a security element integrated into the device;
• ascertaining device properties of the device, which influence a displaying of visually encoded image data on the device, on the basis of the ascertained device type of the device;
• generating an image data representation information item on the basis of the ascertained device properties for generating the visually encoded image data for the device in device-specific fashion;
• generating the visually encoded image data in device-specific fashion according to the image data representation information item for representing the datum on the device.

A system comprising

• a device information unit which is adapted to ascertain a device type of a mobile device on the basis of a user identity which is assigned to a security element integrated into the device, and is adapted to ascertain device properties of the device, which influence a displaying of visually encoded image data on the device, on the basis of the ascertained device type of the device;
• an image data generation unit which is adapted to generate visually encoded image data in device-specific fashion according to an image data representation information item for representing a datum on the device, the image data representation information being generated on the basis of the ascertained device properties by the device information unit or the image data generation unit;
• and
• at least one mobile device which is adapted to display the visually encoded image data generated in device-specific fashion and representing the datum.
