Claim:
1. A system for reading an encoded message, comprising: a scanning device configured to read the encoded message; and an article having a two-dimensional barcode disposed thereon, the barcode comprising: the encoded message in a data area of the two-dimensional barcode, wherein the two-dimensional barcode employs a two-color encoding scheme, a quiet zone surrounding the data area that enables the scanning device to locate the data area, a finder pattern in each of three corners of the data area for allowing the scanning device to determine an orientation of the barcode for reading the barcode, and a finder pattern in a selected region in a fourth corner of the data area configured to disable decoding of the encoded message at the scanning device by preventing the scanning device from determining the orientation of the barcode for reading the barcode, wherein occluding the finder pattern in the selected region from a purview of the scanning device while the scanning device scans the barcode enables the scanning device to orient the barcode for reading and to read the encoded message in a non-occluded region of the barcode.
