Barcode turned 60 years old

On Habré watch for all sorts of anniversaries and anniversaries - and people, and hardware, and programs. But one anniversary is still missed, and the date is quite significant. This is a round date of 60 years - that is how much has passed since the patent for a bar code (1952) was received. However, since the receipt of the patent to the introduction of technology, it took as much as 22 years. Only in 1974, the barcode system began to be actively used, largely due to the emergence of technology that was able to read bar codes. It's about lasers. (Be careful, under the cut "heavy" infographics).

The very first bar code consisted of only four lines. And yes, there were barcodes of the strangest shapes and shapes. At one time there were even round bar codes. And the first laser-read barcode was on the package of chewing gum sold in one of the Ohio supermarkets in that same 1974.

For the time being, the universal barcode system was not approved in other countries, since different manufacturers preferred different systems for recording products and identifying their products.

The other day an interesting infographic was published (English), where the main stages of the barcode system development were noted. Well, happy birthday, barcode!
