FAQ

Questions people ask

Straight answers to what usually decides whether this is the right tool for the job.

Can I change what a badge QR code points to during the event?

Yes. A dynamic code lets you repoint lanyard and signage codes mid-event — from the agenda on day one to the recordings and feedback form on day two — without reprinting anything.

How do I use QR codes for event check-in?

Issue each attendee a code that resolves to their check-in record or ticket page. Staff scan on arrival; because the destination is dynamic, a schedule change or venue move reaches every ticket already issued.

What size should a QR code be on a lanyard or badge?

At least 2 cm square for a code someone scans at arm’s length. For signage read from two or three metres away, scale up to roughly a tenth of the viewing distance — a 3 m read needs about 30 cm.

Can attendees save a speaker’s contact details by scanning?

Yes, with a vCard QR code on the closing slide or exhibitor stand. It saves straight into the phone contacts app without anyone typing an email address.

Do the codes keep working after the event?

They do unless you set an expiry date. Many organisers repoint event codes at the recap page and leave them live, so late scans from leftover printed material still land somewhere useful.
