Sports event registrations

Medical certificates, IDs and receipts checked before registration closes

Races, triathlons and mass-participation events with medical certificates, IDs and bank transfers.

The problem

Hundreds of medical certificates checked by hand in race week.
Every rulebook sets a different maximum age and expired ones slip through.
Transfer receipts that do not match the registration.

With Constaia

A verdict at upload time: the runner fixes the problem before paying.
Age computed against the race date, not today.
You keep only fit, date and licence number; never diagnoses.
