<p>The storage medium (1) has a photodiode for detecting a section of intensity modulation on a screen (14) for a viewer, where the modulation is non-perceptible, selective, continuous and line by line over the screen. Data are transmitted in an encrypted manner over a functional interface by processors, and are stored in a data memory i.e. flash memory. An energy storage i.e. battery, is charged by an interface e.g. universal serial businterface and Firewire. A status indicator visualizes a charging condition of the energy storage. Independent claims are also included for the following: (1) a method for a mobile storage medium (2) a program for executing a method for a mobile storage medium (3) a computer program product with a program for executing a method for a mobile storage medium (4) a computer unit comprising a CPU (5) a method for a computer unit (6) a program for executing a method for a computer unit (7) a computer program product with a program for executing a method for a computer unit.</p> |
