The Hidden Code in Every Barcode

Create a surprising technology explainer revealing how grocery barcodes work. Begin with a macro close-up of a cereal box barcode using a 100mm lens, then execute a rapid rack focus from black lines to a transparent digital data stream. Track the camera through a stylized supermarket aisle as each line expands into animated numbers, product identification, and checkout data. Use clean white retail lighting mixed with neon cyan graphics, smooth motion-control camera moves, and precise captions. A friendly narrator explains that the barcode identifies the product rather than directly storing its price. End with a scan sound and a viewer quiz for YouTube Shorts.
