Most attendance problems are not dramatic. Someone signs for a colleague who is running late. A facilitator adds a few names to make a session look fuller. A photo of the sign-in QR code is shared in a group chat and people check in from the car park, or from home. Each trick is small, but together they make an attendance list unreliable, and that matters when payments, certificates or compliance depend on it.
QRtimer layers several simple checks so that each common trick fails:
- The code on screen changes every few seconds. A screenshot or forwarded link stops working almost immediately, so people have to be looking at the screen. How rotating QR attendance works.
- One phone checks in one person per session. Someone in the room cannot check in a row of absent friends from their own phone. More on stopping proxy attendance.
- Location check compares the phone's position with the venue, which catches the remaining trick: a live photo sent to someone outside. How geofencing attendance works.
- Selfie check-in (Business plan) puts a face next to each name on the attendance sheet. Photos are deleted automatically after 30 days. Selfie check-in and privacy.
- Integrity checks look across all your events for invented or duplicated participants: one phone number registered to several names, a team member's phone checking people in, a participant's code used on a second phone.
- Locked sheets mean nobody can quietly fix the numbers afterwards. Every correction needs an administrator and a written reason, and appears in the report.
