Abstract: A method is to access data stored in a first structured format inside a memory unit of an IC Card. The first structured format may be accessed by a first electronic device including the IC Card. The method may include mapping the first structured format into a second structured format including a plurality of entries, the second structured format being readable by a second electronic device unable to read the first structured format. The method may also include serving at least one query of information about one or more of the plurality of entries, and defining an access control list for associating a list of clients to corresponding access rights to the plurality of entries. The method may further include providing a detector for allowing/not allowing a client of the list of clients to access the plurality of entries through the query of information.
