A boarding pass is the most exact alibi a modern character carries: a name, a seat and a minute, printed by somebody else's computer.
The airline's band across the top, the passenger surname first in the capitals a check-in desk prints, the route from airport to airport, the date, the boarding and departure times, and the stub with the flight, the gate, the boarding group and the seat. The small print carries the sequence, ticket and booking numbers, which is where a clue can sit unnoticed.
At 150 × 62 mm it is a card a player can keep in a wallet, with a stacked barcode the stylesheet draws for you. Export it at 300 DPI, flat or with 2 mm of bleed for a print shop. A steamship, a train or a ferry is a Ticket, and the document the passenger showed at the gate is a Passport.
