Abstract: The invention relates to a system and a method for capturing and evaluating customer behaviour data of customers who are influenced by advertising and/or information in shops, where via hand-held scanners, which can be captured by sensors and are used by the customers when shopping, the customers' routes and times spent in the shop are captured and the purchases are captured chronologically and in a time-accurate manner by the hand-held scanners. At selected places in the shop, output media are arranged via which advertising messages are output in audiovisual or another form in a controlled manner. A data processing system is used to control the output of the advertising messages and to store and evaluate the data captured via the hand-held scanners and the sensors. Via further sensors, fringe condition data such as the outdoor temperature, indoor temperature, air humidity or air pressure can be captured.

Abstract: In a method and a device for controlling the issuing of advertising messages in a sales facility, wherein boundary condition data such as weather conditions and temperature data are detected by means of detection devices arranged inside and outside the sales facility and correlated with effective quantities of sold products promoted by advertising messages. The issuing of advertising messages is triggered in a targeted manner as a function of the results achieved when the boundary conditions determined to be optimal are occurring.
