How to take attendance with a QR code

Put a QR code on screen, people scan it and type their name, and a 4-digit code that changes every 30 seconds stops anyone checking in from outside the room.

Why a plain QR code isn't enough

A static QR code or link can be photographed and shared, so someone at home can “attend”. A rotating code fixes that: the code on screen changes every 30 seconds, and only the current one (or the one just before it) is accepted.

Step 1: Create an attendance check-in

In Pingroom, click New poll and choose Attendance check-in. Or start from a template that already includes one, like First day of class or Training pre-check.

Step 2: Show it at the start of the session

Present it full screen or on a PowerPoint slide with the free add-in. The screen shows your join QR code and the current 4-digit code.

Step 3: People scan and check in

Each person scans the QR code, types their name and the code on screen. One check-in per phone, and names appear on screen as they come in.

Step 4: Get the report

The Attendance page shows who came to which session. On paid plans you can download it as a CSV for your records or LMS.

Questions

Can students check in from outside the room?

Not easily. The code on screen changes every 30 seconds, so a shared photo or link stops working almost immediately.

Is attendance check-in free?

Yes. Check-in works on every plan. Reports across sessions and CSV download are on Pro and above.

Do people need an app?

No. They scan the QR code with their phone camera and check in from the browser.
