Abstract
An integrated circuit card includes a memory storing service data relating to at least one service. At least part of the memory comprises data in file structures within one directory including at least a first file and a second file. The service data is grouped together in at least one service slot. Each service slot is divided into a profile part and a data part. Each profile part has a slot number and is arranged to function as an authorization mechanism. Each profile part is stored in the first file and comprises a unique application identifier. Each data part is at least partly stored in the second file and comprises data related to a given service. And the memory stores at least one key to protect write access to the first and second files. A secure application module and a terminal are also provided for controlling service actions to be carried out by the terminal on the integrated circuit card.
