Blacklight Flight Passport
The all-time passport of an invented flight tracker, Contrail: a passport page with a dotted world map, every route flown as an arc between airport dots, a row of flags, "MY CONTRAIL PASSPORT", 27 flights, the totals and a machine-readable zone, with a Blacklight button. Under the blacklight the screen goes dark violet, the page turns blue and pink and hidden UV security ink appears.
