System for displaying information visually and for data communication

摘要

The system has a manual manageable data processing unit (10) with an image pickup unit (18) that optical-scans the visual information for generating information specific code data and transmitting the code data to a server unit (22) via a public wireless communication network (20). A viewer identifying unit of server unit assigns the viewer individualizing data to the information specific code data. A downstream transaction unit (34) performs a viewer-specific transaction such as payment transaction based on the viewer individualizing data and information specific coding data.
