Use cases
A heart-shaped code for your wedding invitation
Print one heart on the invitation. Guests scan it for the map, the schedule and the RSVP page, and if the details change you update the link instead of reprinting.
Example: a heart-shaped WIA Code.
Looks like part of the card
A heart silhouette sits naturally on an invitation, so the code feels like a decoration and not a technical square.
Change details after printing
If the venue, the time or the RSVP form changes, point the dynamic code to the new link. The invitations you already sent keep working.
No app for your guests
A plain phone camera follows the small booster QR to your link, and the WIA Code scanner opens right in the browser.
How to make one
- Open the generator with the heart shape already selected.
- Enter the link to your invitation page, choose a dynamic code, and download the image.
- Place it on the card and test-scan a printed proof before ordering the full print run.
Before the full print run, scan a printed proof with a phone, and keep the code large and high-contrast.
Why a WIA Code
Your own silhouette
The outer shape is free: heart, square, circle, rose, star and more, or a custom silhouette. A WIA Code is recognised by its center, not its outline.
Change the destination later
A dynamic code points to a link you can edit on My page, so you can change where it goes without reprinting. A plain phone camera follows the small booster QR to that link.
Scan counts
On Pro, your dynamic codes show how many times they were scanned.
