Decoding device with a decoding module () that decodes digital digitally encoded image data. The decoding of said image data is dependent on the programming of an FPGA circuit. In a first embodiment, the key generator for the decoding module is provided with an FPGA circuit. In a second embodiment, the decoding module is provided with an FPGA circuit. The FPGA circuit and/or the FPGA memory can be located in a removable chip-card. The content of the FPGA memory can be updated by the sender over different possible transmission channels.

Decoding device, decoding method and chip-card

A device and method for checking authorization of users, for example, of a public transportation system, in which individual authorization data, containing user-specific data, are stored in personal chip cards and contactlessly transmitted to a portable identification device and visually reproduced by a Virtual Retinal Display.
