Yeah, my school has to wear them on lanyards. Well we are supposed to but most of the time they dont care if you dont wear it. I almost never wear it anymore. We use them for the library and we have ID #s printed on them that teachers use on grade printouts so that "no one know who you are", but then you just look at other peoples IDs because it is big enough you can read them easily. We also use our year book pictures from the year before. Mine is pretty bad.
