Description

Deployed a self-service terminal at the main airport for electronic notarization. Users pay and prepare documents for children before departure; a notary confirms them via video call, and the final document is printed on site.

My focus was a clear step-by-step UI for collecting personal data, live preview, and passport validation.

Functionality

Needed reliable video-conference flow with notaries, strict personal-data validation, and an interface usable by travelers under time pressure at the airport.
