(15)Explanation for Data Matrix c ECC type

Data Matrix contains a function to correct a code reading error using an error correction code (ECC) and restore normal data. Since there are several ECCs. ECC should be designated according to usage. The general correction ability is as follows. However, it may vary according to the error conditions.

dFormat ID

Data Matrix can handle all codes including alphanumerics, symbols and Kanji. Since data compression rate varies according to codes, a code to be used is designated using the format ID.
