QR codes for product labels
Put a dynamic QR code on the label and point it at the manual, setup video or warranty form. When the manual is revised, upload the new version; the label stays the same. Products last longer than most QR subscriptions, and QRVow codes keep redirecting even if you cancel, so a label never points at a dead page.
What to put in the code
The manual
Upload the manual PDF (up to 25 MB, Pro and up). Replace it whenever you revise it.
PDF QR code →Warranty registration
Link to your warranty form. If your website moves, re-point the code.
Dynamic QR code QR code →A setup video
Two minutes of video saves a support call. Upload an MP4 or link to YouTube.
Video QR code →Care details that work offline
A free plain-text code with a batch number or care instructions. It shows on the phone even without signal.
Plain text QR code →Print tips
- Labels are scanned in the hand: at least 2 cm wide, and each little square at least 0.4 mm.
- Short links make simpler codes. A dynamic code's short link fits small labels better than a long web address.
- On bottles and tubes, place the code on the flattest part, not around the curve.
- Label printers can blur. Scan a printed sample, not just the screen.

Questions
What should a QR code on a product label link to?
Whatever the owner needs later: the manual, a setup video, the warranty form, ingredients or care instructions.
How small can a QR code on a label be?
About 2 cm wide, as long as each square prints at least 0.4 mm wide. Our print check measures both from your label artwork.
Can I update the manual after the product ships?
Yes. Upload a new PDF to the same code (Pro and up) or change the link. Labels already out in the world show the new version.
Can I create codes for many products at once?
On Business, the API creates and updates codes from your own systems, and the MCP server lets AI assistants do it. Business has unlimited codes.
What if QRVow shuts down?
We promise at least 12 months' notice. Business plans can print codes on their own domain, and every plan can export all its codes and destinations.
