Abstract

A method is proposed for operating a portable data carrier designed for executing reloadable function programs. According to the method the data carrier initially has installed thereon a loader interface which allows the reloading of load applications which in turn permit the loading of function programs. Each load application has allotted thereto an invariable assigned address space. To support the management of an assigned address space, badges are produced for application programs to be reloaded, said badges containing information about the size of the memory space required for the application program. Address space in the memory device is allotted to application programs to be reloaded in accordance with the size information provided on the badges. A data carrier suitable for carrying out said method is further disclosed.
