QR codes
1. QR codes are Quick Response Codes.
(They are barcodes)
2. Old barcodes one dimensional only vertical.
3. The New codes are
two dimensional –
using both the vertical
and the horizontal to
encode information
(text).
4. They can
hold a lot more
information.

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
