product barcodes do not actually contain the number 666; the barcode pattern for the number 6 is similar, but not identical, to that which represents the guard bar (the barcode pattern for '6' includes a wide white bar, to the right or left of its pattern depending on where within the bar code the number is located; the guard bars do not have this white bar). In a barcode, the only numbers that are actually scanned are those actually displayed in conventional numbers.
