Reed Solomon is an error correction setting that allows a 2D barcode symbol to endure some damage without causing loss of data.

Sometimes printed 2D barcodes are smudged or faxed and lose quality. As a way to prevent misreads, ECL maintains the data in the barcode so that it scans without any errors.

(With Error Correction enabled, the barcode scans accurately)


Error Correction options are available in our PDF417, QR Code, and Aztec 2D barcode products.
