The stop pattern is composed of two overlapped symbols and has four bars. Code 39 bar code symbology specification. The FNC x codes are used for special purposes. However, this feature is not widely supported. Verfahren der automatischen Identifikation und Datenerfassung.

The check digit is a weighted modulo checksum. It is used for alphanumeric or numeric-only barcodes. 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 – Wikipedia

If two consecutive ‘FNC4’ characters are used, all following data characters are extended ASCII isso until two further consecutive ‘FNC4’ characters are encountered or the end of the symbol is reached.

For example, using the patternthe run lengths are 1 digit 11 digit 01 digit 13 digit 02 digit 13 digit 0.

Despite its name, Code does not have distinct symbols, so it cannot represent code points directly.

A scanner seeing the reverse stop symbol then knows it must skip the 2-module bar and read the rest of the barcode in reverse.

Consider the string ” As there are an odd number of 1541 in the middle idc the string, the odd one must be use a different code, set, but it makes no difference whether this is 154117 first or last; 16 symbols are required in either case: Search all products by.

The stop pattern permits bidirectional scanning. Code is one such symbology. A single 1 would be the thinnest line in the bar code. Code bar code symbology specification.

BS ISO/IEC 15417:2007

For instance the code set C value “33” and the code set B value “A” are both considered to be a Code value isso 33, and the check digit is computed based on the value of 33 times the symbol’s position within the barcode. Thus, each symbol begins with a bar and ends with a space.

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, given the string “xy23”, savings on barcode length using code set C are achieved only if it is applied to middle part of the string. Find Similar Items This product falls into the following categories.

Code specifies a combination of 6 alternating bars and spaces 3 of each for each symbol. From Wikipedia, the free encyclopedia. This section gives the compression strategy. At the end of a string, delaying the transition to code set C until there are an even number of digits remaining avoids an extra symbol.


The sum of the products is then reduced modulo There are numerous methods of encoding information in bar code form, known as symbologies. The following table details the widths associated with each bar and space for each symbol. The start symbol and first encoded symbol are in position 1.

Each symbol in the barcode is composed of three bars and three spaces. Using code set C saves one symbol per two digits, but costs a mode-shift symbol to enter and exit the set. The “Shift” symbol switches a single following symbol’s interpretation between subcodes A and B.
