PRINTED INFORMATION DEVICE

摘要

A printed information device (10) includes a region of interest (14) in an image, and at least two channels assigned to the region of interest (14) by different means of logical partitioning. The region of interest (14) 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 (10) is configured to be read substantially simultaneously by at least two distinct reading strategies.
