MOJA — RSVP QR Codes

RSVP QR Codes

An RSVP QR code points at your reply form, so a printed invitation collects answers without anyone typing a URL from a card. The payload is just the link, which is why it works with every scanner ever made.

How to create a RSVP QR code

Build the reply form first The code carries nothing but a link, so the form is the entire product. A Google Form, an Eventbrite page or your own page all work.
Use a link you own, and redirect from it An invitation is printed once and lives on a fridge for months. If the code points at yourdomain.com/rsvp and that redirects to the form, you can change form provider later without reprinting.
Open Create in the app and pick RSVP It sits under Events & Access. Paste the address; the app adds https if you leave the scheme off.
Keep the address short A short link makes a sparser pattern that survives being printed small on card stock. Measured with this site’s encoder, a 40-character address is 29 modules across and a 98-character one is 41 at the same error correction.
Scan the printed proof, not the screen Invitations get printed on textured or coloured stock, which is where contrast fails. A code that scans on a monitor has proved nothing about the card.

What a RSVP QR code is for

The payload is a plain HTTPS address. There is no RSVP format, no reply encoded in the code and nothing that identifies the guest — the code is the same on every invitation unless you deliberately make it different.

That last point decides how you use it. One code for everyone means the form has to ask who is replying, and two people can reply as the same guest. A code per household — a different link, or the same link with a guest token in it — lets the form know who scanned it, at the cost of generating and printing one code per invitation.

For a wedding of 80 households that trade is real: the per-guest version removes the "which Sarah is this" problem entirely, and it is the only version that can tell you who has not replied yet.

Because it is a bare URL, the Website URL generator on this site produces an identical code, free and in the browser. The app’s version keeps it alongside your other event codes; it is not a different kind of code.

Where a RSVP QR code earns its place

Wedding and party invitations

The card carries the code, the form collects names, meal choices and plus-ones, and nobody has to read a URL out over the phone.

Conference and workshop registration

A poster or a flyer that turns into a registration in one scan, where the alternative is a URL people mean to type later and never do.

Internal events and training sign-ups

A code on a noticeboard pointing at the sign-up sheet, which is a page you can close, reopen or cap without touching the printed notice.

RSVP format notes and limits

No signal, no reply. The code carries a link, so the phone has to reach the page. That is usually fine for an invitation read at home and a real problem for a code on a wall in a venue basement.

The code does not know who scanned it. Unless you print a different link per guest, the form is the only thing that can identify anyone, and it can only identify people who tell it the truth.

The link has to outlive the print run. A form provider that closes an account, a free tier that expires, a link with a token in it — any of these turns a printed invitation into a dead end months after you sent it. Point the code at a domain you control.

The address is readable by anyone. Decoding a printed code shows the URL in plain text, so a guest-specific link is only as private as the page behind it. If the link alone reveals the guest list, it is a guest list printed on the invitation.

Nothing expires. The code keeps working after the event. If late replies are a problem, close the form — the code cannot close itself.

RSVP QR codes — questions people actually ask

Does the code collect the reply?

No. It carries a link and nothing else; the form behind it collects everything. That is also why it works with any scanner — there is no format to understand.

Can I make this on the website?

Yes. The payload is a plain URL, so the Website URL generator here produces exactly the same code, free and without installing anything.

Should every invitation get its own code?

If you want to know who has not replied, yes — a per-guest link is the only way the form knows who scanned. If you just need a head-count, one shared code is simpler and prints once.

How small can I print it on a card?

Aim for the code to be about a tenth of the distance it is scanned from, so roughly 2 cm for a card held in the hand — and keep the link short, because a 98-character address needs 41 modules where a 40-character one needs 29.
