I haven't had that problem, but the RFID reader had me paranoid until I mentioned it to a co-worker.

When traveling, I put my passport in the same pocket as my phone.
the phone goes *BING* and vibrates, I take it out of the pocket and see no notifications, so I put it back in my pocket and a few minutes later, same thing *BING/vibrate*
I must have checked my phone at least 20 times, until I was done with my passport an put it in my computer bag.


on the hotel key card thing, the most annoying is when I have a hotel booked for maybe a week, and then I have to extend my stay, that is when I get key card issues.

Go to the reception the day before the original departure and say that I have to extend for another week, they program my key card, then the day after the original departure it stops working... back to the reception and say that it doesn't work, receptionist asks "How long are you staying?" I say another 7 days, and after that, I'll have to program the key card every second day...
grrrrrrrr
