Really? How? I have a fairly recent US passport, and the ability to do it is not clear. (Genuinely curious—this sounds like a neat thing to be able to do.)
- londons_explore 9y agoThe NFC chip in the passport (the wire loop antenna on the page with your photo on) has a bunch of commands you can send it. Only passports made in the last 5 years or so have this. Old passports are paper only and have no such smartness... Hook up an NFC debugger app on an android phone and put your passport next to the phone and you can send it commands. Different countries passports vary, and take different commands etc.
