Error Correction (Code 93i)

The Code 93i symbology supports optional error correction. When the Error Correction symbology option is enabled, a Special Features Flag (character value [52]) is inserted in the middle of the symbol followed by a message length indicator. Code 93i symbols encoded with error correction have six error correction codewords of value [0] to [52] using the Reed-Solomon error correction methodology. Symbols with error correction can be up to a maximum of 52 characters not including start and stop characters.

The Code 93i symbology can be structured in two ways, with either two check characters or with error correction.
