Abstract
A multiple resolution optically encoded label is readable at two more optical resolutions, and is able to store two or more respective channels of optically encoded information. Low resolution information is encoded in a plurality of large cells arranged in a predetermined geometric pattern. Each of the large cells includes a plurality of smaller cells for storing high resolution information. Method and apparatus are disclosed for encoding both high resolution data, and low resolution data, as well as for finding and reading both high resolution and low resolution data.
