1. An identification system comprising a finger ring for use in combination with a control device, said finger ring:

  • having a center (30) and comprising a data storage unit (21) and at least two electrical contact elements (1) connected with the data storage unit (21) and disposed so as to be insulated from each other and to serve for data and/or energy transmission between the finger ring and the control device, and a frontal view of the finger ring being definedwherein, with the viewing direction (31) oriented with respect to the control device in any direction within a pre-selected spatial angular range;

    the electrical contact elements (1) are disposed such that resting places (3) on the contact elements (1) make contact with mating contacts (17) on the control device, with tangent planes (2) to the electrical contact elements (1) at the resting places (3) intersecting each other in a line of intersection (4);

    a parallel plane (5) is defined, passing through the two resting places (3) and disposed parallel to the line of intersection (4);

    normal planes (7) are defined, each passing through one of the resting places (3) and disposed parallel to the line of intersection (4) and perpendicular to the parallel plane (5);

    six spatial regions (8-13) are delimited by the parallel plane (5) and the normal planes (7), namely two inner regions (9,

         12) and four outer regions (8, 10, 11,

         13), with the two inner regions (9,

         12) lying between the normal planes (7);

    first and second groups of spatial regions are defined, with each of the groups consisting of two outer regions (8 and 10, 11 and

         13) on one side of the parallel plane (5) and an inner region (12,

         9) correspondingly opposite with respect to the parallel plane (5);

    the line of intersection (4) traverses the inner spatial region (9) of the second group;

    the inner spatial region (12) of the first group includes areas of the contact elements (1) at which the resting places (3) are in contact with the respective tangent planes (2);

    up to the resting places (3), first subregions of the outer regions (8,

         10) of the first group of spatial regions which lie in front of the contacts (1) do not include a ring element; and

    second subregions (14) which are adjacent to the first subregions, which extend into the second group of spatial regions, and which are delimited by an outer contour of the contacts (1) and parallel to the normal planes (7) and the parallel plane (5) do not include a ring element.
