One scan to call
A phone call QR code opens the dialer with your number ready. People tap Call, and nobody misdials.
Where it helps most
Anywhere typing is awkward: a poster at a bus stop, a dim restaurant, a sign read across a parking lot. Support lines on packaging. Booking lines on posters. On-call and service numbers stuck to equipment.
The caller stays in control
Scanning never starts a call by itself. The phone shows the number and waits for the person to tap Call.
Print the number too
Put the number in text next to the code. People without a camera can still call, and everyone can see who they’re calling before they scan.
Choose a number that lasts
Any number people can call works: a mobile, a landline or a support line. For a business, a main line or switchboard outlives a direct line that changes when staff move. Printed codes stay in the world for years.
Say when you answer
Print your opening hours beside the code. A call that rings out after hours does more harm than no code at all. If the line has voicemail, say so, so people know they can leave a message.
Know which poster works
The code holds no tracking, so nothing about callers is recorded. To compare campaigns, use a separate number for each one, which most phone providers can set up, and count the calls on each line.
Safety and emergency signs
On safety signs, keep the printed number large and treat the code as a convenience. People may be in a hurry, in poor light or without a camera ready.
