Transferring information by optically scanning variable patterns displayed on a graphical display device

摘要

The invention describes a means for presenting variable information contained within a variable pattern displayed on a device with a graphical display capability, such as a liquid crystal display (11) for example, wherein the device presents the information by generating graphical patterns (12) that contain information, such as a two-dimensional barcode (12) for example. The information presented by the display (11) can then be transferred to another device such as a mobile phone (13) for example, by optical scanning of the pattern presented by the graphical display device.
