Abstract
For the purpose of identification, an object is provided with a code field containing a dot code. The code field possesses a certain degree of multiplicity of rotational symmetry (for example, 2, 3, 4, 6). The code field contains information dots from which its orientation can be detected. Redundancy is added which includes the orientation information, so that a certain degree of error correction is possible. By way of example, a suitable code is given for rotationally symmetric objects on which there is not enough space for a bar code.
