How Check-in Works

CompleteEvent includes a built-in check-in tool that works in two ways: a web-based scanner that runs in any mobile browser, or the CompleteEvent iOS app which uses the device camera for faster, more reliable scanning and supports full offline mode. When an attendee registers, they receive a confirmation email containing a unique QR code. At the event, staff scan this QR code to mark them as checked in.

The web-based scanner requires a device with a camera (any smartphone or tablet) and an internet connection. It works on iOS Safari, Android Chrome, and desktop browsers with a webcam. The native iOS app is recommended for large events or venues with unreliable connectivity.

Opening the Check-in Scanner

1. Open your event in the CompleteEvent dashboard.
2. Click Check-in in the event navigation.
3. Click Open scanner. Your browser will request camera permission — click Allow.
4. Point the camera at an attendee's QR code. The scanner will automatically detect and process the code.

When a valid QR code is scanned:

• The screen flashes green and shows the attendee's name and ticket tier.
• The attendee is marked as checked in with the current timestamp.
• The scanner immediately resets and is ready for the next scan.

If a QR code is invalid, cancelled, or has already been used, the screen flashes red with a brief error message. Staff can decide how to handle edge cases manually.

Running Multiple Check-in Stations

For large events, open the check-in scanner on as many devices as you need simultaneously. All devices share the same real-time attendee database — if person is checked in on one device, their code will show as already used on any other device immediately.

A general staffing guideline: plan for 1 check-in station per 50 expected arrivals in the first hour. If your event starts at 9:00 AM and you expect 300 people to arrive between 8:30 and 9:15, that's roughly 6 stations. Under-staffing check-in is the single biggest cause of poor first impressions at events.

Kiosk Mode

For dedicated check-in tablets, Kiosk Mode provides a full-screen, distraction-free interface designed specifically for event staff. To enable it, click Kiosk Mode in the Registration nav or go to Check-in → Kiosk Mode.

Kiosk Mode differences from the standard scanner:

• Fills the full screen — the address bar, navigation, and dashboard chrome disappear.
• Shows a large, high-contrast result screen: green for a successful check-in (with the attendee name and ticket tier), amber for already checked in, and red for an invalid or cancelled code.
• The input field auto-focuses and auto-resets after 3 seconds so the next attendee can scan without staff touching the screen.
• Works with USB or Bluetooth barcode scanners as well as camera-based scanning.

Kiosk Mode is ideal when a dedicated tablet is placed at a registration desk and you want to prevent staff from accidentally navigating away.

Walk-In Sign-In (No Pre-Registration Required)

For drop-in events, open houses, or any event where attendees are not expected to register in advance, you can enable Walk-In Sign-In on the kiosk. When enabled, a “Walk-In Sign-In” button appears on the kiosk screen alongside the QR scanner.

Attendees who walk up without a confirmation code tap the button and fill in their information directly on the kiosk. Their record is created and checked in immediately — no email or QR code needed. The same confirmation is shown as a regular check-in (green flash with the attendee's name).

Configuring Walk-In Sign-In

1. From the check-in hub, click Kiosk Settings.
2. Check Enable walk-in sign-in at the kiosk.
3. Choose which optional fields to collect: phone number, company, and/or job title. First name, last name, and email are always required.
4. Optionally enable consent checkboxes so attendees can opt in to communications from your organization and/or notifications about future events. These checkboxes are pre-unchecked and entirely voluntary.
5. Click Save Settings, then open Kiosk Mode.

Walk-in sign-ins appear in your registrations list alongside pre-registered attendees and are tagged as walk-in records. If the same email address signs in twice for the same event, the kiosk shows an “Already checked in” message instead of creating a duplicate.

Tip: Walk-In Sign-In and QR scanning are active at the same time. You can have one staff member scanning pre-registered attendees while a walk-up queue self-serves on a second tablet.

Session Check-in

For conferences and workshops, you can track attendance at individual sessions — not just at the event level. From the session detail page in your dashboard, use the Session Check-in panel to check attendees into a specific session using their confirmation code.

Session check-ins are recorded separately from event check-in. An attendee can be checked in at the event level (main entrance) and also at one or more individual sessions they attend. Session attendance data is visible in the session detail view.

Manual Check-in

If an attendee does not have their QR code (deleted the email, no phone battery, etc.), you can check them in manually:

1. Click Manual check-in next to the scanner button.
2. Search for the attendee by name or email.
3. Click their name in the search results to check them in.

Manual check-in records the same timestamp and check-in status as QR scan check-in.

The Attendee's QR Code

The QR code is included in the registration confirmation email as both an inline image and an attached image. Attendees can:

• Show the email on their phone screen for scanning.
• Print the email before the event.
• Access their registration at completeevent.app/my-schedule?code=XXXX — this page also shows the QR code and the attendee's personal schedule.

If an attendee has lost their QR code, they can request it be resent from the registration confirmation page, or you can look them up manually and check them in without the QR code.

Viewing Check-in Progress

The check-in page shows a live count of checked-in vs. total registered attendees. The registrations list (Registrations tab) also shows each attendee's check-in status and the timestamp of their check-in.

To see everyone who has not yet checked in (useful near the end of registration), filter the registrations list by check-in status “Not checked in”.

Certificate of Attendance

If you have enabled the certificate of attendance feature (Event Settings → Certificate), attendees can download a personalized PDF certificate after they have been checked in. The certificate is accessible at completeevent.app/certificate?code=XXXX. The URL is included in the post-event follow-up email.

The certificate includes the attendee's full name, event name, event date, and your organization's name. Certificates are generated server-side as PDFs and are print-ready.

Offline Mode

The CompleteEvent iOS app supports full offline check-in. When you open the check-in scanner, the app caches the full attendee list locally on the device. If connectivity drops during the event, scanning continues uninterrupted — check-ins are queued and automatically synced back to the server when the connection returns.

The web-based scanner requires an active internet connection. If you are working in a venue with unreliable connectivity and cannot use the iOS app:

• Export the attendee list as a CSV before the event and print a paper backup sorted alphabetically by last name.
• Use the paper list for manual check-in if the connection drops, then use the manual check-in flow later to record those check-ins digitally once connectivity is restored.

Tip: Always test the check-in scanner with a real QR code and a real device at least one day before the event. Camera permissions on mobile browsers can behave differently depending on the browser version. Test on the specific devices you plan to use on event day.
