Universal Product Code

The Universal Product Code (UPC) is a barcode symbology (i.e., a specific type of barcode) that is widely used in North America, the United Kingdom, Australia, New Zealand and in other countries for tracking trade items in stores. Its most common form, the UPC-A, consists of 12 numerical digits, which are uniquely assigned to each trade item. Along with the related EAN barcode, the UPC is the only barcode allowed for scanning trade items at the point of sale, per GS1 standards. UPC data structures are a component of GTINs (Global Trade Item Numbers). All of these data structures follow the global GS1 standards.

Famous quotes containing the words universal, product and/or code:

    The axioms of physics translate the laws of ethics. Thus, “the whole is greater than its part;” “reaction is equal to action;” “the smallest weight may be made to lift the greatest, the difference of weight being compensated by time;” and many the like propositions, which have an ethical as well as physical sense. These propositions have a much more extensive and universal sense when applied to human life, than when confined to technical use.
    Ralph Waldo Emerson (1803–1882)

    Perhaps I am still very much of an American. That is to say, naïve, optimistic, gullible.... In the eyes of a European, what am I but an American to the core, an American who exposes his Americanism like a sore. Like it or not, I am a product of this land of plenty, a believer in superabundance, a believer in miracles.
    Henry Miller (1891–1980)

    Wise Draco comes, deep in the midnight roll
    Of black artillery; he comes, though late;
    In code corroborating Calvin’s creed
    And cynic tyrannies of honest kings;
    He comes, nor parlies; and the Town, redeemed,
    Gives thanks devout; nor, being thankful, heeds
    The grimy slur on the Republic’s faith implied,
    Which holds that Man is naturally good,
    And—more—is Nature’s Roman, never to be
    scourged.
    Herman Melville (1819–1891)
