Did you hate them as much as I did? I always tried so hard in school to make sure that no one saw it. It tries so hard to be unobtrusive on the front, but how embarassing in high school if people think you have some kind of "lost child" card on you. Even worse if they connect it to JW things.
I hated always having to have it in my backpack, in my wallet, or wear a fanny pack when I went skiing just to make sure it was always with me. I had friends whose parents sewed them into their jackets.
