#### Data and Error Correction Level <a href="#data-and-error-correction-level" id="data-and-error-correction-level"></a>

Naturally, the first step in creating a QR code is choosing the data to encode. We also need to specify an error correction level. Along with the encoded data, the QR code creates error correction codewords that are able to correct error in reading the data, up to a point. The error correction level describes the level of recovery of incorrect data. The higher the level, the higher percentage of data that is able to be recovered.
