This piece of 35mm film shows two different 2D barcodes used in film: Dolby
Digital (between the sprocket holes with the "Double-D" logo in the middle) and
Sony Dynamic Digital Sound (in the blue area to the left of the sprocket holes).
Embedded digital audio is but one use of 2D barcodes.
A matrix code, also known as a 2D barcode or simply a 2D code, is a
two-dimensional way of representing information. It is similar to a linear
(1-dimensional) barcode, but has more data representation capability.
