How to Use the Bulk Event Badge QR Generator
Badges do two jobs at once: they tell people who someone is, and they let staff verify access. A QR code on a badge adds a third job, because it can be scanned at session doors, workshops, and meal counters to record attendance or check a ticket tier. This tool generates a batch of badge QR codes from a simple attendee list, so organizers can print a whole conference's badges without building each code by hand.
Keep badge data minimal and readable. Name and role are what other attendees actually read; the QR code carries the same information plus the event name for verification. Use roles consistently, such as Speaker, Attendee, Volunteer, Staff, or Exhibitor, because inconsistent role labels make it hard for door staff to decide who belongs in a restricted session. If your event has tiers, put the tier in the role column, for example Attendee VIP, rather than inventing a separate code.
The trade-off with badge codes is between openness and control. A code that anyone can scan and read is friendly for networking, since attendees can exchange details by scanning each other. A code that only your staff app understands is better for access control, since it cannot be read and copied by a stranger. For most events, encoding name and role openly is fine, but do not encode phone numbers, emails, or hotel details on a badge that will be worn in public.
Print badges large enough to read at a handshake distance, with the name in big text and the QR code at least 3 cm wide. Use a lanyard or clip that keeps the code flat, because a curled or folded badge will not scan. Test scanning at the actual check-in desk, with the lighting you will have on the day, and print a handful of blank badges for walk-ins and replacements.
A detail that separates smooth events from chaotic ones is the replacement plan. Decide before the day how replacements are issued, who authorizes them, and how the original badge is voided, because the moment someone reports a lost badge is not the moment to invent a policy. Keep a small stack of blank badge cards and a marker at the registration desk, and log every replacement with the time and the name of the person who issued it. After the event, review the replacement log: a handful of losses is normal, but a pattern of losses at one entrance usually means badges there were easy to lose or easy to take.
