QR LapScan in five short steps.

The smartphone reads QR wristbands, counts laps, and helps volunteers with registration and lap tracking – right on event day.

This guide works best on two devices, for example a laptop and a smartphone, since the QR codes are scanned with the app from the screen here.

Assign QR code.

Helpers can assign a free QR code on site to participants who weren't prepared in advance or signed up late.

To do this, the smartphone is connected to a station in the event portal. There, you select the participant and then scan a free QR code. It can then immediately be used to check and count laps.
