Other nations print mythical creatures, waterfalls, and entire animal worlds on their passports. Ours features the federal eagle, formally correct and about as exciting as a form field. Yet the truly great journey still lies ahead, and to this day there's no passport office for Mars.
Until that changes, the Passport Holder Sovereign Territories of Mars with RFID Protection takes over the official role: red synthetic leather, gold embossing with rocket, planetary seal, and laurel wreath. Inside, compartments hold your boarding passes and credit cards, while an elastic band keeps everything together. Built in is also a layer that blocks electromagnetic waves. Contactless bank and access cards carry radio chips, and if you want to be safe, simply shield them. On Mars, no one will be patrolling at first anyway, so you'll need to protect yourself.
For everyone who'd rather think about launch pads than queue numbers while waiting at passport control. The first colonists always board first, after all. ;)
