I recently got my new RFID Passport, and I was concerned about identity theft while travelling, so I looked around for an inexpensive RFID protector wallet.  This one has a nice pocket to tuck the cover of the passport into, and it is easily removed for scanning.  It is low profile, and pretty nondescript, so I think it does the job. One of the nice features is that there is a little space to tuck some other cards and/or papers if you need it.  I used them to put my med info in.  This is worth what you pay.
