Abstract  Abstract

The data exchange system includes at least one portable data processing unit (5) the unit (5) comprises a communication device (14) and processing device (15) and storage device (16); the latter comprises a executable program (17) and one or more application descriptions (18 (1) 18 (n)) each application description including at least one interaction context (19 (1)) the context comprising commands data elements data references process access conditions and external references; to achieve such efficient smart card to use the limited storage space of the selected data element and data reference and other reference structure.

Data exchange system comprising at least one portable data processing unit (5) comprising data communication means (14) processing means (15) and memory means (16) the latter comprising an executive program (17) and one or more application descriptors (18(1)...18(n)) each application description comprising at least one interaction context (19(1)...) comprising commands data elements data references procedures access conditions and external references; the structure of the data elements and the data references as well as other references is chosen in such a way that a very efficient use of the restricted memory space of e.g. smart cards is obtained.
