Events Day-of Toolkit

When event day arrives, Muin gives you a live check-in board on the web and fast check-in tools on your phone. This guide covers the web Day-of Check-in board, mobile QR and NFC check-in, assigning NFC cards, and taking walk-up ticket payments at the door.

When you’d use this

The doors open in ten minutes and you need a registration desk.
You are tracking volunteer hours and need both arrival and departure times.
Someone turns up who never registered and you want them on the roster anyway.
You are giving attendees NFC cards before the event so the door moves faster.

The Day-of Check-in Board (Web)

Open your event’s management screen and choose Day-of. The board refreshes attendance automatically and gives you one check-in desk with three inputs:

Camera, scan the attendee’s QR code from their confirmation
Card or badge tap, hold a card or badge to a connected reader
Manual entry, type the credential when neither works

Under the desk, + Walk-in adds someone who never registered: it creates the person and an attended registration in one step, asking only for a name and a contact detail.

On a volunteer event with shifts and roles, the walk-in goes into a shift and role. If that one is already full, the person at the door is still seated. The seat is recorded as a walk-in override, so the coordinator’s roster shows who went over the limit and why. Freed spots are not offered to the waitlist until the shift is back under its limit.

Find a volunteer (no scanner) searches the roster by name or email for the no-scanner path. Each row on the roster has its own actions:

Check in, mark the person as arrived
Check out, record departure, with hours served for volunteer hour tracking
No-show, flag a registrant who did not arrive

Check-in, check-out and no-show can all be undone from the same row, so a mistaken tap is not permanent.

When the event requires a waiver, a volunteer who has not signed it cannot be checked in. The board shows why and offers Record signature. Hand the device to the volunteer to sign in Volunteer’s signature; for a volunteer under 18, a parent or guardian adds their name and signature too. Select Record signature and the check-in goes through. The signature then appears on the volunteer’s What I signed page. A + Walk-in for such an event is refused the same way until a waiver is on file. If the refusal is about a missing date of birth rather than a signature, there is no button: add the date of birth to the volunteer’s record first. You do not have to mark every volunteer no-show by hand. About an hour after a volunteer event ends, Muin marks anyone still registered but never checked in as a no-show. People who were checked in are never changed. If a volunteer came but was never checked in, for example they signed a paper sheet, undo the no-show on their row.

You can select several volunteers and add extra hours to all of them in one action.

Who can run the board. Day-of check-in is its own permission, not a tenant-admin role, so you can give a door steward exactly that and nothing else: the Door Check-In Steward role. A steward reaches the board from Events, then Check-in, which lists the events they can check people into from today onward.

Revenue by ticket type and a CSV export of the full attendee list, including payment status, are on the event’s management screen rather than the check-in board.

Mobile Check-in (Muin Go)

In the Muin Go app, open Events, pick your event, and tap Check In. You’ll need the day-of check-in permission, the same one the web board uses. Two scan modes are available, switchable at the top of the screen:

QR scan: point the camera at the attendee’s QR code from their confirmation.
NFC card: hold the attendee’s card to the back of the phone; scanning runs continuously so you can tap cards one after another.

Each scan shows an immediate result: checked in (green), already checked in (amber), or not found (red). A live counter tracks progress: “42 / 120 checked in.”

Works offline. If the venue has no signal, check-ins queue on the device and sync automatically when you’re back online.

If a card or QR won’t read, the error tells you what to do next. For example, a card nobody holds says to assign it first or check the attendee in by name, and a card that was removed or reported lost says to assign the person a new card.

Assigning NFC Cards

Any registered attendee can hold an NFC card: a volunteer, a ticket or RSVP guest, or a student.

In Muin Go, open the event and tap Assign a card. It lists the attendees who do not have a card yet.
Pick the attendee and hold their card to the phone. Muin binds the card’s chip to that person. Nothing is written to the card, so any NFC card works.
The card belongs to the person, not the event, so it works at every check-in they attend. Assigning a new card replaces the old one, and a card that already belongs to someone else is refused with their name.

Lost card? Remove it or mark it lost on the person, from the volunteer profile or from Assign a card. It stops working everywhere at once.

Walk-up Ticket Payments

For paid events, staff can sell tickets at the door with tap-to-pay:

In Muin Go, open Pay → Event Ticket. Only events with a ticket price appear.
Pick the event, enter the attendee’s name and email, and tap Pay.
The attendee taps their card or phone to complete payment.

You can also start a payment from the event detail screen: tap Capture Payment to jump straight into the payment flow with the event pre-selected.

Before the Doors Open · Quick Checklist

Event is Published and capacity is set
Staff phones have Muin Go installed, signed in as someone with the day-of check-in permission
Whoever is running the desk holds the day-of check-in permission
Badges written (if using NFC): allow 5-minute sessions per batch
Day-of Check-in board open at the registration desk
For paid events: tap-to-pay tested with a small charge

When it goes wrong

What you see	What to do
“No registrations yet, use the walk-in button above.”	Nobody has registered, or you are on the wrong event. Check the event name at the top; otherwise check people in as walk-ins.
“No volunteers match” your search	Clear the search box. The search matches name and email on the existing roster only, someone who never registered will not appear, so use + Walk-in.
A card or badge tap does nothing	The desk reads a credential; an unrecognised one gives you the name-search path instead. Use Find a volunteer (no scanner) and check the person in from their row.
“Could not add walk-in”	The walk-in was rejected. Check that the name and the email or phone are filled in, then submit again.
The board will not open at all	Day-of check-in is a separate permission. Ask your owner or admin to grant it to the person running the desk.
You checked in the wrong person	Undo it from their row. Check-in, check-out and no-show are all reversible.
A badge reads revoked	That badge was retired. Issue a new one to the attendee from the badge-writing flow.
Phones show nothing after a scan at a venue with no signal	Expected, check-ins queue on the device and sync when you are back online. Do not re-scan the same person repeatedly.
