Introduced in the 1970s, the Universal Product Code (UPC) is a barcode symbology that became widely used in the United States, Canada, United Kingdom, Australia, New Zealand, in Europe and other countries for tracking trade items in stores.
Not everybody was happy with the prospect of the UPC. The popular satirical publication Mad Magazine dedicated the entire cover of issue #198, originally published in 1978, to a giant UPC bar code, with the subversive caption, “…hopes this issue jams every computer in the country … for forcing us to deface our covers with this yecchy UPC symbol from now on.” Throughout the next two years, subsequent issues featured humorous descriptive captions for the smaller symbol, including “Hair of man watching horror movie" and "Close-up of the gap in Alfred E. Neuman's teeth.”
Since then, barcodes have evolved, both standardized and proprietary, for many uses such as product tracking, parcel tracking, digital information sharing (the ubiquitos QR code) and more.
Here are some examples:
Your task, should you choose to accept it, is to find the suitable barcode(s) and read it.
This is by no means a simple task and you may be required to think outside the box too.
Once you have that information, you know what to do with it.
