Visa × Scotiabank
TIFF 2026 screening invitation for Scotiabank Passport cardholders, moved to a capacity-reached state once registration closed.
The problem
A cardholder screening that would oversubscribe, on a page that had to stop taking registrations gracefully rather than keep collecting names it could not honour.
What we built
A registration flow with a real capacity ceiling and a designed capacity-reached state, so the page closed itself cleanly instead of failing or misleading late arrivals.
