Abstract: An individual identification system is a modular combination of a person-related first unit with transmittable/receivable storage elements by way of an antenna, the unit operating alone or together with a further unit having an additional, but different, identification part, and a person-unrelated and instead object-related second unit for the interaction between the person and the object and with a control for checking and maintaining the interaction with which units and objects are crosslinked. The person-related first unit is carrier oriented and is permanently or removably located on a use article, e.g., on a key, in a pass, on or in a watch or any other object which changes position with the person and is not coordinate-fixed. The object-related second unit is place-oriented and is at fixed locations (e.g. building doors), or is arranged in fixed manner on moving objects (e.g. vehicles).
