Question

If 2400 codewords are to be encoded in a QR code, of which 750 need to be corrected, which QR code error correction level must be used?

Answer 1

If 2400 codewords are to be encoded in a QR code and 750 need to be corrected, then the QR code error correction level that must be used is Level H (High). Level H is capable of correcting up to 30% of all codewords, which is more than enough for the given requirement.
