The check symbol is calculated from a weighted sum modulo of all the symbols. It is calculated by summing the start code ‘value’ to the products of each symbol’s ‘value’ multiplied by its position in the barcode string.
The check digit is a weighted modulo checksum. Oec and continue Learn more about the cookies we use and how to change your settings.

The start symbol and first encoded symbol are in position 1. 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. The sum of the products is then reduced modulo It is mandatory at the left and right side of the barcode. Therefore this version remains current. 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.

Code set C is used to efficiently encode digit strings. Using code set C saves one symbol per two digits, but costs a mode-shift symbol to enter and exit the set. Final text received or FDIS registered for formal approval.

If during this sequence of extended encodation a single “FNC4” character is encountered ixo is used to revert to standard ASCII encodation for the next data character only.

FNC1 at the beginning of a bar code indicates 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. Each symbol in the barcode is composed of three bars and three spaces.
Proof sent to secretariat or FDIS ballot initiated: The stop pattern permits bidirectional scanning. If the following symbol is a shift, then a second symbol will be used to obtain the character.
