Code 93 Extended
Code 93 Extended is an extended version of the Code 93 barcode. Unlike the basic version, it is capable of encoding 128 ASCII characters instead of 48.
Set of characters:
- digits 0-9;
- capital letters A-Z;
- special characters:
$
,%
,/
,+
.
Code structure:
- start character
*
; - the encoded information – a data character consists of three lines and three spaces. The width of a line or space can be from 1 to 4 modules;
- a check digit calculated using the "C" modulo;
- a check digit calculated using the "K" modulo;
- stop character
*
.
The check digit numbers are not displayed in the text under the code. The checksum consists of two digits, which are calculated in different ways: modulo "C" and modulo "K". The calculation formula is the remainder modulo 47 of the sum of the data value weights. The difference between "C" and "K" is the methods of weighting the values.
As mentioned earlier, Code 93 Extended allows the encoding of 128 characters. However, additional characters ($
, /
, %
, +
) must be used to expand the standard Code 93 character set. Thus, to encode lowercase letters, a combination of the +
character and the corresponding uppercase letter is required. The remaining modifier characters are needed to expand the set of special characters.
