Error correction levels for QR codes.
Error correction levels.
What level of error correction should be encoded into the QR code. A higher error correction means that the resultant QR code is more likely to be scannable even when damaged. These correspond to the L/M/Q/H levels defined in the QR Code spec. (see, for example, http://en.wikipedia.org/wiki/QR_code)
