I am pretty paranoid about my wallet, which means that I usually have a pretty good sense of awareness about where it is. (I am so used to it being in my pocket that when I have my wallet in my hand I sometimes have a mild panic about my wallet missing. Doh!) That said, I would not put a large device like this in my wallet, because I don't perceive the benefit as worth the cost of a larger wallet and missing card slot. Still, the idea and implementation seem to be excellent. I would be much more likely to attach a tracker to my luggage while traveling or in my laptop bag. With a smaller device I might even put it on my keyring. If I had one in my car I wouldn't have to think about remembering my parking spot. The GPS tag will mark it for me as soon as I leave my car.
