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. Code bar code symbology specification Status: You may find similar items within idc categories by selecting from the choices below:.

The initial subset is selected by using the appropriate start symbol. The remainder is then converted back to one of the non-delimiter symbols following the instructions given below and appended to the barcode, immediately before the stop symbol. In other projects Wikimedia Commons. Please download Chrome or Firefox or view uec browser tips.

Either solution requires the use of an application or an application is in to calculate the check digit and create the barcode. 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. Search all products by. Thus, each symbol begins with a bar and ends with a space.

If two FNC4s are used consecutively then all following characters will be treated as such, up to the end of the string or another pair of FNC4s. The two stop symbols are merged into a unit long stop pattern. If during this sequence of extended encodation a single “FNC4” character is encountered it is used to revert to standard ASCII encodation for the next data character only. Code 39 bar code symbology specification.

The faster, easier way to work with standards. Graphical symbols for use on information technology and telecommunications technical drawings and in relevant technical product documentation. The checksum is computed over the symbol values, without regard for which code set is active at the time. Automatic identification and data capture techniques. Text Compression for Bar Codes”. You may experience issues viewing this site in Internet Explorer 9, 10 or The check digit is a weighted modulo checksum.

The technology of bar coding is based on the recognition of patterns encoded in bars and spaces of defined dimensions. The stop pattern permits bidirectional scanning.

This page was last edited on 23 Novemberat The Algorithm Design Manual 2nd ed. Each bar and space is 1 to 4 modules wide, and the symbols are fixed width: The minimum width of the Quiet Zone to the left and right of the Bar Code is 10x, where x is the minimum width of a module. Each symbol in the barcode is composed of three bars and three spaces.

There are numerous methods of encoding information in bar code form, known as symbologies. FNC1 at the beginning of a bar code isi a GS bar code which begins with a 2- 3- or 4-digit application identifier assigned by the Uniform Code Councilwhich explains the following digits.

For instance, encoding the ASCII character “0” can be viewed aslec a sequence of 1’s is a bar and a sequence of 0’s is a space.

Code specifies a combination of 6 alternating bars and spaces 3 of each for each symbol. Especially the ASCII char of value 0 and of value 95 and above may be defined differently in the font that is installed. For example, in the following table, the code variant A checksum value is calculated for the alphanumeric string PJJC:.
