Links move. Prints don’t.

A regular QR code is the link itself, drawn in squares. Print it, and it points there for good.

The menu moved. Every copy on every table now opens a dead end, and the only fix is to print them all again.

Same print. The link follows the clock.

A live code points through qrcdn, so where it goes can change after it’s printed. By hand, or by the clock.

Free to print.
$4 if it might change.

Fixed codes are free and never expire. Cancel Live any time: each live code keeps working on its last link.
