Claim:
1. A coding device for marking positions in a lift shaft and for determining the position of lift cabins in the lift shaft, comprising a code band, wherein: the code band has at least three markings arranged along the length of the code band in order to mark discrete positions in each case, the markings are embodied as a barcode and/or 2D code, the markings are arranged in such a way that they form rows and, in particular, there are at least as many rows as there are discrete positions to be marked, the markings are embodied in such a way that they comprise a position marker for each discrete position to be marked, the markings are decodable by means of an algorithm, wherein, in particular, there exists a mathematical function which uniquely assigns each marking of a position to the corresponding position, at least one bearing device is provided for bearing the code band in the lift shaft such that it can be moved, in particular be moved longitudinally, said bearing device being embodied to overlap the code band at least partly, preferably completely, and being embodied in such a way that it carries a marking, in particular a barcode and/or a 2D code, arranged in such a way that it covers at least part of the marking of the code band in a readable manner when overlapping the code band.
