Not at all. I worked apart time job delivering parcels that were scanned with a specialized bar code scanner. Most of the parcels had dual barcode/QR codes for the tracking number. You would be surprised how much damage could be done to the QR codes before they were unreadable. Even if the QR code had small folds over itself the codes would still read. The barcodes were unreadable with the slightest amount of damage or ink bleed.
