Change a QR code destination after printing

Update a saved dynamic resource, preserve its redirect address and test the same printed code after the change.

Create your first QR code

Go from the right content type to a readable download and a tested print using the QRinio creator.

Static or dynamic QR codes: which fits?

Compare direct encoded content with editable redirects. Choose based on updates, offline use and responsibility for the link.

QR code size and print quality

Choose physical size for the content, viewing distance and material. Preserve the quiet zone and test a real print sample.

Add a QR code to Word and Office documents

Insert a QR image into a document, keep its proportions and verify it after exporting to PDF or printing.

How long does a QR code remain valid?

Understand static and dynamic QR code lifetimes, unavailable destinations and the checks to make before printing materials intended to last.

Understand QR statistics and UTM campaigns

Tell QR requests, short-link clicks and website visits apart. Plan UTM campaigns and understand repeated requests, bots and limited event detail.

QR code security: recognising quishing

Check destinations before opening QR links, spot replaced stickers and protect your own QR campaigns from unwanted changes and abusive content.
