Code 93 was introduced in 1982 as a high-density complement to Code 39. It uses two check characters, which are not shown in human readable text nor transmitted to a scanner. It supports all 128 ASCII characters.

• Control characters, such as TAB or NEW LINE, may be encoded by entering their three digit ASCII code prefixed by a caret (^). For instance, 1234^009 will encode 1234 followed by a tab character (ASCII 009).
• To encode FNC1, enter: ^F1
• To encode the actual caret character: ^, escape it by entering it twice: ^^. For example, to encode ABC^DEF, enter: ABC^^DEF
