You may experience issues viewing this site in Internet Explorer 9, 10 or FNC1 at the beginning of a bar code indicates a GS bar code ieec begins with a 2- 3- or 4-digit application identifier assigned by the Uniform Code Councilwhich explains the following digits.
The shifts are done using code points 98 and 99 in code sets A and B, in code sets A and C and in code sets B and C to switch between them:.
Take the smart route to manage medical device compliance. Each bar and space is 1 to 4 modules wide, and the symbols are fixed width: The technology of bar coding is based on the recognition of patterns encoded in bars and spaces of defined dimensions.

For example, in the following table, the code variant A checksum value is calculated for the alphanumeric string PJJC:. Verfahren der automatischen Identifikation und Datenerfassung. In barcode oso, the final bar is generally combined with the stop symbol to make a wider stop pattern. The faster, easier way to work with standards.
BS ISO/IEC 15417:2007
The following table details the widths associated with each bar and space for each symbol. You may find similar items within these categories by selecting from the choices below:. The width of each bar or space may be 1, 2, 3 or 4 units modules.
When the stop pattern is read left-to-right the usual casethe stop symbol followed by a 2-module bar is recognized. There are numerous methods of encoding information in bar code form, known as symbologies.
Two of the symbols are used for stop end-of-barcode indication, stop and reverse stop. 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 initial subset is selected by using the appropriate start symbol.

Monday to Friday – Each bar or space is 1, 2, 3 or 4 units wide, the sum of the widths of bars must be even 4, 6 or 8 unitsthe sum of the widths of the spaces must be odd 3, 5 or 7 unitsand total 11 units per symbol.

A single 1 would be the thinnest line in the bar code. Learn more about the cookies we use and how to change your settings. The checksum is computed ie the symbol values, without regard for which code set is active at the time. Consider the string ” However, this feature is not widely supported.
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. Code specifies a combination of 6 alternating bars and spaces 3 of each for each symbol.
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 “Code A”, “Code B” and “Code C” symbols cause all future symbols to be interpreted according to the corresponding subcode. The check digit is a weighted modulo checksum. The FNC x codes are used for special purposes. Using the example above, an ‘A’ would be depicted with the patternor as widths in the tables below.
When the stop pattern is read right-to-left, the reverse stop symbol followed by a 2-module bar is recognized. 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. The start symbol and first encoded symbol are in position 1.
