🧑‍🏫One QR Code for the Whole Room

Reading a web address aloud to a room wastes the first minutes of a session. A QR code on your opening slide lets every participant open the same page at once, whether that is your slide deck, a shared folder, or a course page. Say what the code opens, leave it on screen long enough for the back row to scan, and make it large enough to read from there.

Most sessions need more than one link: slides, the agenda, an exercise sheet, a feedback form. Rather than showing four codes, point one code at a single page or shared folder that lists them all. Participants scan once and return to that page throughout the day. Add the same code to the door sign and the printed handout so latecomers and remote colleagues are not left out.

The free static QR code suits a one-off session or a course page whose address never changes. Its destination is fixed, so you update the content at that address rather than the code. If you print workbooks or certificates and run the course again, a dynamic QR code lets you point the same printed code at the next cohort's materials. You can also switch it from the slides to the feedback form at the end of the day.

Keep access control in the platform that hosts your materials. A QR code is only a link, so anyone who has it can open whatever that link allows. Test it with the permissions your participants will have, and show a short typed address beside the code for anyone who cannot scan. Scan analytics show how many times a code was opened and when; they do not record who attended or confirm that anyone completed the course.
