Short explanations of how a QR code holds a link, and how to print one that still scans.

• Static and dynamic QR codes

  A static QR code stores the destination. A dynamic QR code stores a redirect. The redirect is why a free code can die after a few days.

• QR codes that do not expire

  A QR code does not have an expiry date. It stops working only if the address inside it stops working, or if it stored someone else's redirect.

• Make a QR code for a website

  Use the full https address, leave a quiet margin, and choose Medium damage tolerance for a normal web page.

• Print a QR code

  Print from the SVG when you can. Use black on white, keep the quiet zone, and scan a proof before the full run.
