For whoever ends up on the door
At the door, the question is not who was invited but who is standing here. A personal QR per guest answers it in a single scan, and the arrival list shows who is inside as they come.
Somebody prints the guest list on paper, stands at the door with a clipboard, and spends the first hour squinting. Is it Anna who said yes with a partner, or was that a different Anna? A relative mentions bringing a friend, and the person at the desk has to look it up, interrupt your day, and hope the handwriting is right.
Check-in by QR removes all of that. Each confirmed guest carries a personal code, from their phone or a card, and the moment it is scanned their name moves to present on a live arrival list. The door becomes a quick hello instead of a search party.
Two halves, one guest and one person at the entrance.
The scan answers a narrow, useful question, and nothing more.
On the day, the list of arrivals is the live picture: everyone you can account for, and the gap that tells you who is still to come.
One scan per guest keeps the entrance moving, which matters when thirty people arrive in the same ten minutes.
At the end you know exactly who turned up, because each present name was confirmed by a scan rather than a guess at the clipboard.
This is door check-in tied to your guest list, not an analytics dashboard. You see arrivals, which is the number that matters at an entrance, and nothing more elaborate than that. The point of the QR is that a guest's presence registers against their name the instant they cross the threshold, so the arrival list is true while the day is happening, not reconstructed afterward from memory or a lost clipboard.
The same idea runs backwards through the day. Before the event your guest list holds the confirmed names; at the door those names become present; after, the list tells you who came and who said yes but never arrived. It is one continuous record with a scan in the middle, which is why a single QR per guest matters so much. Anything a code could be used for beyond that, tracking opens, timing arrivals to the minute, reporting on who lingered, is not what this does.
The scan only works if the guest has their code on them when they arrive. Two ways to make sure.
How it works
Replies build the guest list of who is coming. Each confirmed name is the guest a personal code will be issued to.
Each person on the list gets their own code, on the phone they arrive with or on a card you printed. One code, one named guest.
At the door you scan the code. That marks the guest present on the live list, and it takes a second.
Watch who is inside update as people come, so you always know who has arrived and who is still on their way.
Questions
No. The code is on their phone or on a card you printed, and the person at the door does the scanning. The guest just shows up with their code.
Each guest gets their own personal code, which is what lets a single scan mark that specific name present. A shared code could not tell you who actually arrived.
They are simply not on the confirmed list yet. You can add a name on the day and check them in, so a walk-up or a plus-one you allowed is still accounted for.
Yes, that is the flip side of the arrival view: names on the list that are never scanned show as present-not-yet, so you can see who said yes but did not come.
Get Started
Give each confirmed guest a personal QR, scan once as they arrive, and read a live picture of who is inside instead of a paper list you are afraid to lose.
