QR Codes and Digital Identifiers for Everyday Products

When a printed code that smudges after one wet weekend touches a folding camping chair, a shop assistant in a campsite shop with a phone based till should reach a code list that maps each code to its batch and name the affected units, and that is exactly what giving each batch a scannable code that points at its own record makes possible.
