code-93-extended

The code-93-extended bar code is an extended version of the code-93 bar code.

Some scanners support an "extended mode", in which the scanner recognizes special two-character sequences of the code 93 character set and decodes these as ASCII characters. With this extended mode, the full 128 character ASCII character set can be encoded using the 47 basic characters of code 93.

The nominal height is 1in. The nominal width of a bar is BARWIDTH=0.022in. The width of the entire bar is (1+( noDigits+2)*9)*BARWIDTH. The padding on both sides measures 10*BARWIDTH.

This code type automatically creates the necessary two-character sequences and can be used as a more convenient way of creating extended code 93 bar codes.
