-64. (canceled)
A multimode machine-readable symbol comprising:
- a first machine-readable symbol instantiated on an object at a first location, the first machine-readable symbol readable by a first methodology;
- and
- a second machine-readable symbol instantiated on the object at a second location that overlaps the first location, the second machine-readable symbol readable by a second methodology different from the first methodology.
A method of decoding a multimode machine-readable symbol having a first machine-readable symbol instantiated on an object at a first location and a second machine-readable symbol instantiated on the object at a second location that overlaps the first location, the method comprising:
- acquiring an image of the multimode machine-readable symbol;
- processing the image to separately evaluate first and second characteristics of the image, wherein the first characteristics arise from the first machine-readable symbol and the second characteristics arise from the second machine-readable symbol;
- applying a first methodology to decode the first machine-readable symbol from the evaluated first characteristics;
- and
- applying a second methodology to decode the second machine-readable symbol from the second evaluated characteristics.
