A ticketing and QR access-control platform of its own that validates every ticket in under a second and does away with third-party platforms.
HANGAR organises open-air afternoon parties and concerts at the Pla de Bages aerodrome, near Barcelona. It needed to sell its events without depending on third-party platforms, keep its attendees in a database of its own, communicate with them by email and control access on event day from a phone.

The challenge
A live event chains five processes: promotion, ticket sales, communication with attendees, access control and post-event analysis. Ticketing platforms cover part of that and retain the data. HANGAR needed a single tool of its own covering all five.
It also had to work at the critical moment: hundreds of people at the door, several stewards scanning at once from their phones, no guaranteed coverage and no possibility of the same ticket being used twice. All in Catalan and GDPR compliant.
Our approach
A site with HANGAR's identity: upcoming and past events, gallery and FAQ, with a page per event containing the practical information and access to purchase. A short form, online payment and a QR-coded ticket on screen immediately, with a copy by email. Email and ID unique per event, so no attendee registers twice.
A panel with search and filters (all, checked in, pending), manual registration, CSV export and one-click ticket resend. Each event shows its registrations, check-ins, pending entries and new sign-ups of the day.
Campaigns per event and per segment (buyers, attendees, pending), with tracked links: each ticket retains the campaign or channel it came from, so the performance of each action is measured by the tickets it generates.
A door mode keeps the camera active and validates each QR code in under a second against the server, showing name and ID. Each ticket's state resides on the server, so several stewards can work at once without a ticket being used twice. At the technical layer, an email queue with retries, per-IP limits and daily backups.

The impact
The ticket appears on screen once payment completes and arrives by email. The link is permanent and can be forwarded.
Validation in under a second from a phone, with no data entry, several stewards at once and no double entries.
Attendees reside in HANGAR's database, segmented by event and status. Each email campaign is measured by the tickets it brings in.
One attendee per email and ID, consents recorded with a date and a CSV ready for the next campaign.
Every season is prepared with the same tool. We keep working with HANGAR on an ongoing basis, evolving the platform with each edition.
