Code is one such symbology. The “Shift” symbol switches a single following symbol’s interpretation between subcodes A and B.

Bar code print quality test specification. Life cycle A standard is reviewed every 5 years 00 Preliminary. It specifies the symbology identifier 115417 strings for Code symbols. It is used for alphanumeric or numeric-only barcodes.

Barcode reader Barcode printer. It is mandatory at the left and right side of the barcode. For the beginning and ending part of the string, switching to code set C is not effective. The Algorithm Design Manual 2nd ed. For instance, encoding the ASCII character “0” can be viewed aswhere a sequence of 1’s is a bar and a sequence of 0’s is a space.

You may find similar items within these categories by selecting from the choices below:. Manufacturers of bar code equipment and users of bar code technology require publicly available standard symbology specifications to which they can refer when developing equipment and software.


Optimizing the length of the resulting barcode is important when barcode readers are used which must detect the entire barcode image at once in order to read it, such as common laser scanners. Reporting just the lengths of each run gives 1, 1, 1, 3, 2, 3, thereby producing a widths value of There will always be 6 runs and the lengths of these 6 runs form the Widths value.

The FNC x codes are used for special purposes. Your basket is empty.

Code bar code symbology specification. All articles with unsourced statements Articles with unsourced statements from May Wikipedia external links cleanup from January Wikipedia spam cleanup from January This page was last edited on 23 Novemberat Code includes symbols: For instance the code set C value “33” and the code set B value “A” are both considered to be a Code value of 33, and the check digit is computed based on the value of 33 times the symbol’s position within the barcode.

The initial subset is selected by using the appropriate start symbol. Especially the ASCII char of value 0 and of value 95 and above may be defined differently in the font that is installed. The check symbol is calculated from a weighted sum modulo of all the symbols. Automatic identification and data capture techniques. Despite its name, Code does not have distinct symbols, so it cannot represent code points directly. Three 1’s in sequence indicates a bar three times as thick as a single 1 bar.

Retrieved from ” https: If two consecutive ‘FNC4’ characters are used, all following data characters are extended ASCII characters until two further consecutive ‘FNC4’ characters are encountered or the end of the symbol is reached. For example, in the following table, the code variant A checksum value is calculated for the alphanumeric string PJJC:.

In the past, symbology specifications were developed and published by a number of organizations, resulting in certain instances in conflicting requirements for certain symbologies. Views Read Edit View history. Check out our FAQs. The width of each bar or space may be 1, 2, 3 or 4 units modules.

Code specifies a combination of 6 alternating bars and spaces 3 of each for each symbol. All widths are multiples of a basic “module”. However, this feature is not widely supported. For the purpose of computing the check symbol, the shift and code-switch symbols are treated the same as any other symbol in the bar code.
