Abstract
We describe a method for encoding information on stacked rows of bar codes. Each row uses one of three sets of codewords. When a single scan crosses data rows the difference in codewords can be used to organize the collected data correctly. The code provides for error detection and error correction both at the level of the codewords and at the whole message level.
