Abstract:
A printed information device includes a region of interest in an image, and at least two channels assigned to the region of interest by different means of logical partitioning. The region of interest represents a physical area of the image. Each of the channels has a different error tolerance. Continuous and/or cyclic information is independently encoded in each of the at least two channels. The deterrent is configured to be read substantially simultaneously by at least two distinct reading strategies.
