many of us have heard talks (either in official tracks or, more likely, unofficial breakout sessions) where folks discuss how it is possible to place a sticker over the UPC bar code on a retail product and make it ring up differently by the checkout scanner. often, this is done by folks who are (illegally, it should be noted) trying to not pay as much for their purchases. (often the technique i see discussed involves keeping a brand and good the same but changing the size... i.e. having a 16 oz. package of Philly Cream Cheese ring up as a 4 oz. package.)
there seems to be another use for UPC hacking that is being explored, however... it is being reported that Wal-Mart is selling products with fake/modded UPC stickers on top of the bar codes on recalled/unsafe pet food.
this news piece leaves some gray area as to whether everyone's most hated big-box retailer is responsible for meddling with things or if the actual supplier of the tainted vittles (Menu Foods) was messing with the packaging.
UPDATE: after reading other sources and looking more deeply into this, it appears that Menu Foods is taking the blame for a "packaging mix-up" wherein they have changed supply lines (again we see products from China being very sub-standard and causing health issues) and were (apparently) using their existing packaging (with the recalled UPC code) and adding a sticker to show the update.
geez, though... you'd think that someone would have said "this is a bad idea and could get some people in a twist here" and they would have fallen on their sword and just ate the costs of a new run of packaging production. could they really have huge WAREHOUSES of empty pacakges that they didn't want to waste? If that's the case, how does the food product come from China (or wherever) in the first place? In huge tanker containers, from which it's sort of poured out like a meaty sauce?
