The barcode — that small square of numbers and parallel lines that's on almost every product sold in a store — turns 60 this month.

The now-ubiquitous patch was first patented in 1952. The first design, invented by Norman Joseph Woodland and Bernard Silver, resembled a circular bullseye.

CBC's Catherine Cullen looks at the history of the barcode and how companies are now adapting the technology for the future — including turning humans into living barcodes.
