Title: ORGANISING DATA IN OPTICALLY READABLE DATA ELEMENTS
Abstract:
The invention relates to a method for organising data for storage in one of one or preferably at least two optically readable data elements suitable for transferring a data set from a physical medium to a terminal. Such data elements are preferably matrix code elements. According to the method the data are organised in a data format comprising an introductory header (21) and a following data field (22). The header (21) is composed of a first field (23) indicating a global unique identifier, which unambiguously identifies the data set concerned, a second field (24) indicating a number in the sequence of data elements, a third field (25) indicating over how many optically readable data elements the data set concerned is distributed, and a fourth field (26) indicating which type of data is contained in the data set. The following data field (22) contains the data set concerned, or a part of the data set concerned if the data set is stored in more than one optically readable data element.
