Frequently Asked Questions
How does a QR code attendance tracking system work?
The instructor or event host generates an attendance QR code linking to an online check-in form (such as Google Forms or Microsoft Forms). Attendees scan the displayed code on their phones, authenticate, and submit their attendance in seconds.
Can I link my attendance QR code to Google Forms or Microsoft Forms?
Yes. Utilvo supports all cloud form URLs. Simply paste your Google Form or Microsoft Form share link, customize the styling, and display it on projector screens or printed classroom cards.
How can I prevent students or attendees from sharing the attendance QR code remotely?
Best practices include setting short form submission response windows, enabling single-response Google account authentication, or displaying a dynamically refreshed check-in code at the start of the session.
Is an internet connection required to scan an attendance QR code?
The attendee needs mobile data or WiFi to open and submit the web check-in form, although the QR code scanning itself happens offline using the phone's optical camera.
Can I print attendance QR codes on classroom desks or badges?
Yes. Download in vector SVG or high-resolution PNG at 300 DPI to print durable, scannable badges, desk stickers, or entrance signage that withstands daily physical use.
