Nowadays, QR codes are used for everything from augmented reality advertisements to authenticating designer jeans, to sharing Wi-Fi passwords. They were invented in 1994, grew insanely popular, disappeared, and then made a comeback-mostly because you no longer need a dedicated app to use them.

To combat this, a single character check digit is often used with messages of fewer than 10 digits, and a two-character check digit is used for longer messages. Here is our example again, diagramed for clarity:Ĭode 11 is considered a weak or insecure symbology, as a single print or read error can result in a misinterpreted character. The symbology is further characterized as a discrete barcode, meaning that each character is separated with an inter-character gap element (typically a single white element, though larger gaps are permitted). The symbology also includes distinct start and stop characters. Of these five elements, two are always “wide” (twice the width of a “narrow” element), and three are always narrow. Below is a simple example.Įach character in a Code 11 barcode consists of 3 bars (black) and 2 spaces (white)-every character starts and ends with a bar. The data in the barcode is represented linearly by these black/white (bar/space) patterns. This means the barcode is composed of a single set of varying width vertical lines and spaces. Code 11 is a linear, one-dimensional (1D) barcode. Code 11 is variable length with the only limit on length being the width available for print. The symbology can encode the digits 0 through 9, a dash, and includes both a stop and start character. Code 11 (also called USD-8) is a numeric-only barcode developed by Intermec in 1977.
