Familiarity: I've used it several times
Picked this up for a recent international trip. Chances probably weren't really that high that I'd actually get my info scanned but it was nice having the peace of mind. It was also nice having my passport, cards, and money all fit snugly into this one pocket. I either kept it in my front pants pocket or in an inner pocket of my backpack but I could also see this working great attached to a belt and tucked into your waist or even on a sturdy lanyard and hung around the neck.
