means for applying an optical character recognition process to said container code image to create an estimated container code;

means for acquiring a first container code image from said video imaging device of said container representation of said container code; and

means for compressing said first container code image to create said container code image;

wherein said video imaging device belongs to a collection comprising at least a video camera, a digital video camera, and a charged coupled array.

3. The system of claim 2,

wherein the means for acquiring said container code image is further comprised of at least one member of the collection comprising:

means for selecting a first of at least two of said video imaging devices; and

means for acquiring said container code image from said first video imaging device of said container representation of said container code.
