UPC-A barcodes are 12 digit long. There are many many other types of barcodes, including 2D barcodes that can hold up to 1K of data on them. They just have to pick another type of barcode, like CODE128, for consumer products and declare it the new standard. No need for revolutionary changes here.
Look in the SUPPORTED_BARCODES file in the cuecat driver [easyconnect.fr] archive to see how many 1D barcode types already exist.

Current UPC barcodes use only digits 0-9 so they are only 10^12 in range, which is a lot smaller than 2^64, or for that matter 2^96.
My question is whether they are still stripes or use 2D coding (I am assuming 2D, unless they use compressed printing and or improved 'variable width' scanning units).
Barcodes are a series of wide and thin transitions (or heights as in postnet) which in certain combinations of multiples of transitions represent numbers. The stripes themselves may either be static representation of each character (code 3 of 9) or more complex representations (like interleaved 2 of 5) but in general they are binary, even 2D codes are also mainly binary in design either on or off but in a grid or hexgrid format.
