[Feature] QR code self check-in for physical presence validation

[Bytrider]

Hi,

we are using the app to manage attendance for exercises and events, and we encountered a practical issue with remote check-ins.

Problem

Currently, users can register or check in to an appointment from anywhere as soon as it becomes visible or available.

This leads to situations where people who are not physically present (e.g. at home) can still mark themselves as attending, which makes attendance data unreliable.

Feature request

Introduce a QR code based check-in mechanism per appointment.

Proposed behavior

• The appointment organizer can generate a QR code for the event
• The QR code is only available to organizers/admins
• At the event location, the QR code is displayed (e.g. printed or on screen)
• Participants scan the QR code to check in

Access options

After scanning the QR code:

• Logged-in users can confirm their attendance
• Users without an account can check in as guests (enter name)

Optional enhancements

• QR code is only valid during a defined time window
• Check-in only possible via QR (disable manual check-in)
• Location-based validation could be an optional extension

Use case

During exercises, we want to ensure that only participants who are physically present can check in.

This prevents incorrect attendance data and ensures fair participation tracking.

Benefit

• Reliable attendance tracking
• Prevents remote/invalid check-ins
• Supports both internal users and external guests

Thanks for considering this feature.

@Bytrider As written in one of the other issues: I would highly recommend to have only some key users that are able to to the check-ins via the check-in-view - you can already limit it by admin settings to a certain group of users.

But good news: I am already developing the mobile app for attendance - it will soon spawn in Apple App store and Google Play store - so a QR code checkin and/or NFC tag checkin will be available in the near future :)

Thanks, that sounds great — especially the upcoming mobile app with QR/NFC support.

Just to clarify the main use case on our side:

The issue is not only who is allowed to access the check-in view, but also how to ensure that only people who are physically present can confirm attendance.

Restricting the check-in view to specific groups is helpful for organizer-managed check-ins.
However, for our exercises, we would ideally like participants to confirm their own presence on site by scanning a QR code displayed at the event location.

So for us, the main benefit of QR/NFC check-in would be:

proof of physical presence
self check-in on site
optional support for guests and existing users

If this is already planned for the mobile app, that would cover our use case very well.

Thanks again — looking forward to it.

Cool then I keep you up2date as soon as the self check is done and the app launches. :)

Currently I am still implementing "real push" for the native app so people are getting a much faster push to interact with if they missed to answer an appointment or if an urgend "send immediately as push" appointment was created.

Update: the mobile app is now live! 🎉

• iOS: https://apps.apple.com/de/app/nextcloud-anwesenheit/id6759988681
• Android: https://play.google.com/store/apps/details?id=de.krautnerds.attendance

The QR code based self check-in feature is coming in one of the next releases. Keeping this issue open to track the QR/NFC check-in work specifically — will close once it ships.

@Bytrider the qr code and/or NFC scan feature will be released around beginning of august!
