QR code structure (from wikipedia) • The diagram illustrates the placement of the message characters within a QR code. • Starting from the lower-right corner, the first four bits define the encoding used (in this case, 8 bits per character). • Next is the length of the message (17; dark stands for 1, but the masking process used in this symbol inverts alternate rows). Following that is the message itself, then the end-of-message marker, and finally the error-correcting codes. You don’t need to know any of this
