Re: morningdeer: Yeah UPCYes, to ID products that's how they are conventionally used. That doesn't mean it will always be the case. I'm talking about LE deliberately making the people who make the packages use barcodes or QR codes which ID either a box of packages or even an individual package. For national security, blah blah blah....Does anybody know the search space for UPC and QR codes? How big is it?
