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.
