I purchased a RFID passport and credit card wallet last year and still use it in my purse, however, its too large to place inside a money belt.  So, I purchased this passport shield and also some credit card shields, and all of them can fit securely in my money belt too.  So, if you're looking for something to secure your passport from electronic theft, then I would definitely suggest one of these.

*I just noticed that the previous reviewer indicated that they thought they were getting 3 passport sleeves like the photo. The photo doesn't even show a a passport sleeve, but is showing credit card sleeves. Its probably a mix up in the photo, but the product is what it is and designed to work. All of these type of sleeves run about the same unless you buy a multi-pack and I travel solo and have no need for more than one passport sleeve.  I'm very happy with my purchase in knowing it fits my passport exactly how it should fit, without any alterations or work on my part.

I've also reported the image error to amazon for correction.
