    摘要: A product and method for decoding information is provided. The product includes a sensor for detecting a plurality of marks on a surface to obtain associated mark location data, at least a first group of the plurality of marks being arranged on the surface so as to define an invisible raster with predetermined dimensions and marks in at least a second group of the plurality of marks are displaced from raster locations in a manner encoding information, and a processor for receiving from the sensor at least some of the mark location data, the processor determining, using the received mark location data, a position of the invisible raster on the surface, and decoding information based on positions of at least some of the marks in the second group of the plurality of marks relative to locations on the invisible raster.
