Frequently asked questions about QR codes
Do QR codes expire?
Static QR codes never expire because the destination is encoded directly into the image. Dynamic QR codes keep working as long as the redirect stays active. With OwnQR, a dynamic QR is a one-time $15 with no monthly fees and no expiry.
Can I change where a QR code points after it's printed?
Only with a dynamic QR code. A static code locks in the destination, so changing it means reprinting. A dynamic code points to a short redirect you can edit anytime, even after printing, and the code image stays the same.
Are QR codes free to create?
Yes. Generating a static or redirect QR code is free. Upgrading a code to dynamic, which adds an editable destination and scan analytics, is a one-time $15 with OwnQR and has no subscription.
How do I track how many times a QR code is scanned?
Use a dynamic QR code. Your dashboard shows total scans, scans in the last 7 days, the top device, and the top cities, so you can see how a printed code is performing.
What can a QR code link to?
Any destination URL: a website, WiFi network, vCard, PDF, social profile, music or video link, restaurant menu, or event page. The QR simply opens whatever URL it points to.
