InforZoom ULO by redystum

In the large lecture halls and classrooms at the Polytechnic Institute of Leiria (IPLeiria / ULO), instructors often project the QR code for attendance tracking onto the projector screen.

For students sitting in the back rows, the camera on their cell phone or laptop often cannot focus on or read the QR code because it appears too small in the frame.

InforZoom solves this problem directly in the browser, allowing you to zoom in up to 5x so that the scanner can recognize the QR code instantly, even from a great distance.
