QR codes for flyers and posters
Use a dynamic QR code on flyers and posters, so you can fix a wrong link, change the offer, or keep the poster useful after the event. Print one code per location and you can see which spot gets scans. Posters stay up long after a campaign ends, and QRVow codes keep redirecting even if you cancel.
What to put in the code
A link you can change
The main one. Fix mistakes after printing, and give each batch or street its own code to compare scans.
Dynamic QR code QR code →A discount
Scan to reveal the offer and the code to use. After the end date, the page says the offer has ended.
Coupon QR code →The event date
Gig and class posters: one scan saves the date to the phone's calendar.
Calendar event QR code →Text a keyword
A static SMS code with a word like JOIN already typed. People just press send.
SMS QR code →Print tips
- Size by distance: the code should be at least one-tenth as wide as the distance to the reader. A poster read from 2 m needs a 20 cm code.
- A4 and A5 flyers held in the hand: 3 to 4 cm.
- Put the code between chest and eye height, never at the bottom edge where other flyers cover it.
- Say what people get, like "Scan for 20% off". A bare code gives nobody a reason to scan.

Questions
How big should a QR code be on a poster?
At least one-tenth of the scanning distance. Read from 1 m, 10 cm wide; from 3 m, 30 cm. Never smaller than 2 cm.
Can I track how many people scanned my flyer?
Yes, with a dynamic code. Make one code per batch or location to compare them. Free shows total scans; Pro adds scans by day, country and phone type.
I printed the wrong link. Do I have to reprint?
Not if the code is dynamic: change the destination. A static code holds the link in its pattern, so that one has to be reprinted.
What if someone sticks a fake QR code over mine?
Check your posters now and then, and watch your scan counts: a sudden drop can mean a sticker. Anyone can see where a code really goes with our free QR safety check.
Do QR codes on flyers expire?
QRVow codes don't. Static codes can't, and dynamic ones keep redirecting on every plan, even after you cancel.
