Abstract
A method for storing or reading data in a memory array is described. The application data file includes an application data length indicator indicating a memory size of first application data stored in the application data file in compliance with a predetermined protocol. The method for storing additional data comprises checking whether a memory size of the application data file is larger than the memory size indicated by the application data length indicator and storing second application data in a partial memory area of the application data file not occupied by the first application data. Thereby, memory areas which, according to the predetermined protocol, are not used, can be used for new applications, data can be hidden in these areas such that they cannot be read by protocol compliant reader devices, and the data structure is compatible with the former predetermined protocol.
