![]() ![]() This limits Code 25 Interleaved to storing an even number of digits, but it is much more compact than Code 25 Industrial. ![]() Thus, every 10 bar/spaces represent two digits (as compared to Code 25 Industrial, where every 10 bar/spaces represent a single digit). Here is the example again, diagramed for clarity:Ĭode 25 Interleaved (also known as Code 2 of 5 Interleaved, Interleaved 2 or 5, or ITF) is a variant of Code 25 Industrial that stores data in pairs, with 5 bars representing one digit, and the 5 spaces interleaved within the bars representing the second digit. For this reason, some users of Code 25 Industrial implement their own check-digit as part of the data encoding. However, Code 25 does not include a check digit and is not self-checking (meaning, a single read/scan error can result in incorrect decoding). Like most other one-dimensional barcodes, Code 25 uses unique start and stop characters. This inter-character gap does not represent any data. Here is an example barcode:Ĭode 25 Industrial is further characterized as a discrete barcode each data character in the barcode is separated from the next with an inter-character gap (a single narrow space). Each data character consists of 5 bars/spaces, 2 of which are always wide (hence the name, 2 of 5).Ĭode 25 Industrial (also known as Code 2 of 5) only encodes data in the bars of each symbol, using narrow spaces between each bar. Both symbologies use two-width encoding (narrow bars/spaces and wide bars/spaces, with the wide width being 2 to 3 times the narrow width). There are actually two Code 25 symbologies: Code 25 Industrial and Code 25 Interleaved. Code 25 is a numeric symbology: it can only be used to represent the digits 0 through 9. The data in the barcode is represented linearly by these black/white patterns (also called bars/spaces). This means the barcode is composed of a single set of varying-width vertical lines (black) and spaces (white). In addition, the Barcode Scanner SDK supports a broad range of symbologies to meet your growing development needs.Code 25 (also called Code 2 of 5) is a linear or one-dimensional (1D) barcode. You can download the SDK for free by registering on the Cognex Mobile Barcode Developer Network. The Cognex Mobile Barcode Scanner SDK supports Code 11 detection, enabling developers to gather relevant workflow and application data into their own apps. Code 11 is primarily used in the labeling of telecommunications equipment. While developed as a high-density, numeric barcode, because of its poor reliability, Code 11 is not widely used. In the preceding examples, the last digit (8) is actually the computed check digit for the data message (4321). 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. ![]()
