i can see this being hacked by some nerd at every college to link to HOTorNOT.com
i would like that to be soon before i enroll for refresher courses in the near future.
as for attendance taking, i guess this beats swiping the attendace book from the principals office a couple times a year as you can now just have your friend/girl friend hold up a photograph to the scanner!
as for any privacy issues i've had my picture on my student ID since i was in highschool decades ago and attendance records were kept since i was in kindergarten so not only did they know where i was, and what i looked like, they had my name and classes and books i checked out, what i ate, since it was used also as your library card and lunch card.
just sayin..this isn't anything new or that isn't already used. everybody's got a yearbook with far more information about you in it.
