QR codes for weddings and celebrations
Wedding QR codes work best on the invitation for RSVP and on table cards for photo sharing. The design trap is foil and dark card stock — both look right and neither scans.
Foil and dark stock do not work
Foil has no reliable luminance contrast — a camera sees a bright reflective patch, not dark modules. Dark ink on dark card fails for the same reason, even when it looks deliberate.
Print the code as dark ink on a light panel, even if that panel is a small light rectangle set into an otherwise dark design. This is a constraint, not a suggestion.
On the invitation
Point at a single wedding page holding everything: RSVP form, directions, accommodation, gift list, dress code, timings. One code beats four.
Add a calendar event so the date lands in the guest's phone, and a location code pinned at the actual entrance — venue postcodes often resolve to the middle of an estate rather than the gate.
On the tables
A photo-sharing code on each table is the highest-value on-the-day code: guests upload to a shared album instead of the photos being scattered across fifty phones. Point it at a shared album that does not require an account, or you will lose most contributions to the login screen.
Longevity
People keep invitations. If the wedding page is taken down afterwards, the code becomes a dead link in someone's keepsake box. Leave a simple page in place with the date and a thank you — it costs nothing.
Size
Invitations are read at arm's length, so 2–2.5 cm is enough. Table cards the same. There is no need for a large code here, which helps the design considerably.
