(15) Explanation for Data Matrix
c ECC type
Data Matrix contains a function to correct a code reading error using an error
correcting code (ECC) and restore normal data. Since there are several ECCs, ECC
should be designated according to usage. The general correction ability is as shown
below. However, it may vary according to the error conditions.
ECC type Error Correction Ability Overhead by ECC
ECC0 0%
ECC50 25%
ECC80 33%
ECC100 50%
ECC140 75%
ECC200 Approx. 30%
d Format 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.
Format ID Code Details
1 Numerics 0 to 9 space
2 Letters A to Z space
3 Alphanumerics, symbols 0 to 9 A to Z space . , - /
4 Alphanumerics 0 to 9 A to Z space
5 ASCII (7 bit) 00H to 7FH
6 ISO (8 bit) 00H to FFH (Kanji)
e Maximum number of digits
The maximum number of digits varies according to the ECC type or format ID.
Since each Kanji character uses 2 bytes, the maximum number of digits for it becomes
half of the following values.
ECC0 ECC50 ECC80 ECC100 ECC140
Format ID 1 500 457 402 300 144
Format ID 2 452 333 293 218 105
Format ID 3 394 291 256 190 91
Format ID 4 413 305 268 200 96
Format ID 5 310 228 201 150 72
Format ID 6 271 200 176 131 63
Numeric Alphanumeric 8 bit
ECC200 2000 2000 1556
