    After encoding the data for a QR code, you must generate the error correction codewords. Error Correction Code ECC Definition - Error correction code ( ECC) checks read or transmitted data for errors and corrects them as soon as they are found. The error detecting and correcting capabilities of a particular coding scheme is correlated with its code rate and complexity. The code rate is the. Writing correction code.
