Save the contact
Scanning prompts the phone to add Spencer's name, phone, email and website straight to contacts. Best for vans, leaflets, business cards.
Both QRs encode permanent redirect URLs (/qr and /qr/c) β not the website URL directly.
That means if you ever change domain (e.g. to a new .co.uk), the printed QRs keep working β we just edit one line in _redirects to point them to the new home.
Print once, use forever.
