1. A method for data correlation having the steps: in a pick-up device with an image acquisition element that is included in a mobile terminal: acquiring a first image, which represents a physical object, acquiring a second image, which represents coded information relating to the physical object, generating at least one object data record from at least one acquired first image and an identification label which uniquely determines an object-related acquisition procedure, generating at least one information data record from at least one acquired second image and the identification label; in a correlation device spatially separate from the mobile terminal and connected thereto by means of at least one network: extracting the coded information from the information data record, semantic interpretative analysing of the extracted information in order to establish which parts of the extracted information have which semantic meaning, and generating at least one combination data record from the results of the semantic analysis, the extracted information and the at least one object data record with the same identification label as the extracted information data record; and in a user device which is included in the mobile terminal: storing and further using the combination data record.
