Most Barcode readers do not require barcode internal data encoding to be
specified in order to read the barcode. However, Data Matrix barcodes do
support internal error detection and correction. The level of error detection
and correction is known as the ECC level.
The use of ECC allows for codes to be partially damaged but remain read-
able. The amount of error correction built into a Data Matrix barcode does
not limit the data capacity of the barcode.
The HCSF supports Data Matrix barcodes for all ECC levels.
