you're talking about like the parents being able to track their kids. yea, that's up to the parents if they want to do that. but total tracking by the school?
i worked the bus ramp and parent pickup every day as a teacher. it's always a mess. if a kid wants to skip the bus or catch a ride or just plain walk out - they can get away with it. A few times a week, we'd have an irate parent because he kid did this or that. And if a pedo wanted to steal a kid, they could get away with it. Just too hard for 30 staff members to control 800 kids for dismissal.
I like the idea of me, as a parent, being able to call teh office and they'd be able to say "Little Barry scanned Onto the bus at 3:15 pm and scanned off at 123 main street stop at 3:35 pm. Or, "Your son Carter scanned for parent pickup at 2:48 pm and went to this person who is on your approved list".
Do I think chertoff and his nuthuggers are a bunch of chickenhawk scaremongers bent on getting paid on the exploitation and control of the population? Sure! But I do like this idea because it'll help keep track of kids in a very chaotic daily environment.
