QR Code

QR Code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional code) first designed for the automotive industry. More recently, the system has become popular outside the industry due to its fast readability and large storage capacity compared to standard UPC barcodes. The code consists of black modules (square dots) arranged in a square pattern on a white background. The information encoded can be made up of four standardized kinds ("modes") of data (numeric, alphanumeric, byte/binary, Kanji), or through supported extensions, virtually any kind of data.

Famous quotes containing the word code:

    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)
