Which is the dilemma between selling multiple quantities of an
identical item, and using the barcode as a asset number.  Since ppl
don't need to remember barcodes, why not add an extra, say, 128 bits
at the manufacture stage, starting at 0 for every unique product.
You wouldn't need to store the entire number, hashing it with the
unique product number would do...
