As soon as my RFID passport arrived, it went into the microwave for a few seconds. No smoke, no discoloration - just a slightly raised outline.

And no more RFID.

But is it then, technically, still a valid passport?

Valid enough for human validation! (Although, I think it's technically illegal to deface a passport. But, at the same time, it's not technically 'defaced'...)

Edit: As a frequent (if reluctant) traveler, I've yet to encounter a necessity for RFID at passport control. (I simply avoid that particular queue.)

I've been stopped twice for not being obedient: once because I refused to step into a mm-wave scanner (after the controller refused to send me back through the metal detector after I removed my belt...), and another time for not staring into the hypnotic blinkenlights that were swirling around the cameras above everyone's heads in the queuing area.

Can you elaborate on the 'hypnotic' lights? I've never seen or heard of this.

I think it was UK Gatwick Airport, on the way to passport control. The passengers were shepherded into lines, and spaced at intervals above each line were ceiling-mounted cameras. Bright LEDs around the camera lens were flashing in rotational patterns - designed to instinctively draw attention, and hence make facial recognition easier.

Were there four lights? Or five?

I really can't recall. I wasn't looking up!

No, but the kind of person who writes things like that never leaves his basement anyway, so he doesn't need a valid passport.
