Start with a stable destination
Encode a public HTTPS URL you intend to keep. A QR code containing an old address will still point there after you redesign your page.
Test the actual print
Scan a proof on different phones, in realistic lighting and at the intended size. Keep clear space around the code and avoid stretching it.
Static and managed codes
A static code stores the URL itself. A managed redirect can change its destination, but depends on the service hosting that redirect. Own Bio Link does not currently generate or manage QR codes.
