Onsite badge printing at scale: Lisbon Congress Centre
30,000 attendees, 15 distinct badge designs, 65 badge printing stations
Â
Conference Badges provided a full onsite registration and badge printing service for a major international event at the Lisbon Congress Centre on five different occasions.
The event has grown from 10,000 to nearly 30,000 attendees. This included delegates, speakers, exhibitors, sponsors, VIPs, media, and operational staff, each requiring a distinct badge type with specific access permissions and visual identification.
The brief was to keep registration moving at the pace of the event, ensure every attendee received the correct badge, and set a professional, organised tone from the moment the doors opened. With up to 14 badge categories and 40 ticket types in play, and attendee data changing right up until arrival, pre-printing was never a realistic option.
Challenge: Large scale, high data complexity and attendee data that never stops changing
Â
The registration team was tasked with handling:
- Up to 30,000 attendees arriving across concentrated peak windows, with no tolerance for queuing
- 14 distinct badge designs, each linked to different access levels, branding rules, and visual identification requirements
- Attendee data that continued to change up to the point of arrival with late registrations, amended details, last-minute additions
- Brand, design consistency and sponsorship across every badge category, from general delegates through to VIPs and sponsor guests
- Management of session-specific and area-specific access, where the badge itself served as the primary visual credential for security and hospitality teams
Solution: 65 printing stations with automated badge assignment
Â
To keep registration moving across a venue of this size, Conference Badges deployed 65 badge printing stations spread across the registration area, positioned to prevent traffic building at any single entry point.
Each station automatically matched the attendee to the correct badge design at the moment of printing. This removed the need for staff to manually select from 14 templates, which could have introduced both delay and error. The correct access level, layout, and branding were applied every time without manual intervention.
For security and session management teams, the 14 visually distinct badge types meant attendee categories were identifiable at a glance. Hospitality staff directing VIPs, session managers controlling room access, and security teams monitoring restricted areas could all make decisions from the badge alone, without needing to check lists or scan codes at every touchpoint.
During the morning rush, all 65 stations ran near capacity, but queues never built up. During mid-afternoon lulls, the operation scaled down. The infrastructure was designed so that peak periods produced no queues and quiet periods produced no idle stations.
Result: registration that kept pace with a 25,000-person event
Â
The combination of automated badge assignment and flexible station deployment meant the organisers never had to intervene in the registration process or worry about whether the system could handle demand.
Benefits to the organisers:
- Every badge printed live at check-in, with data accurate to the moment of arrival rather than the last spreadsheet export
- Automatic template assignment across all 14 badge categories, with no manual selection required
- Late registrations, data amendments, and last-minute additions handled without disruption
- Zero pre-print waste across the entire 25,000-attendee run
- Compostable badge stock, eliminating post-event landfill from printed materials
- Clear visual distinction between all 14 attendee categories, supporting security, access control, and hospitality operations
- A registration experience that set a professional tone from doors opening to final check-in, with no visible queues or pressure
Successes
Â
Metric | Outcome |
| Attendees registered | Up to 30,000 across concentrated peak periods |
| Printing stations deployed | 65, scaling up and down with demand |
| Badge categories | 14 distinct designs, automatically assigned at print |
| First-time accuracy | Near-perfect, with minimal reprints despite volume |
| Pre-print waste | Eliminated: every badge produced on demand |
An operation at this scale required more than printers and paper.
It involved infrastructure planning, station layout designed to prevent bottlenecks, trained technicians capable of troubleshooting under pressure, and automated systems that removed manual decision-making from a 14-category badge assignment process.
