Yes, absolutely right. Since mislaying a set of keys (including a Banham one that is both expensive and a pain to replace), I went and ordered a set of key fobs from TheTrackR.com. They are pretty small, very light and can easily be attached to or hidden within a bag. Now all of my and Senior Management’s keys and baggage (plus her handbag) are trackable pretty much anywhere from my/her iPhones. They could, as easily, be attached/taped to a ski bag or whatever. The TrackR fobs also allow you to find where you’ve left your iPhone…!
BTW, I have no commercial relationship with TheTrackR.com beyond being a customer.
