I don't see how this is better, my first thoughts: more difficult to print, more difficult to scan, vulnerable to light shifts (imagine trying to scan a can with colored bar code in a club with flashing lights) and impossible to print in some technolgies.
Bar code won't go away exact for the reason it's super simple to scan and print. Even QR codes can't stand that (and if you tried scanning yourself grocery in soft bag with barcode in the corner which gets crumpled you know what I mean).
