Yes, years ago I broke both the UPC and Postal barcode systems with no prior knowledge of their encoding systems and for a while after breaking them could read them visually (however I'm out of practice now and would have to refresh myself on both). The 2D codes are much more difficult to read, but in principle a person could read them too.

How are bar codes read?
Bar codes are read by a bar code reader. A low-powered laser in a bar code scanner emits a beam that crosses the bar code, generating a series of light and dark reflected flashes. These are read by the sensitive laser detector in the scanner and decoded to produce the numerical values shown on the label. These are compared to the codes in the store's computer to identify the item, look up the price, and add it to the register bill. Modern self-service check-outs have lasers that scan in two perpendicular directions, to read barcodes in any position relative to the scanner.
