Seems crude, but aren't you talking about an RFID warehousing system?

Hey Kind Folks,
I've been asked to create something and I thought I'd pick
brain before possibly entering into the wheel reinvention game.
Does anyone know of a computerized system for keeping
track of attendance
that would function with the kids themselves (k-12)
entering their own
comings and goings into the system? As I sit down to
design this I'm
imagining all kinds of data integrity nightmares with
clicking "sign in" and "sign out" buttons that are next
their (or someone
else's) name. This would be some sort of kiosk by the
front door. I'm
thinking that if I use a web interface (I am a web
programmer), I'll use a
thin client for this.
This is for a free school, where kids can enter and leave
the school at
different times. There is no "home room" or designated
check in time.
Right now, kids sign in on paper, but it is making
reporting and tracking
trends difficult. I'm toying with the idea of using
facial (and possibly
voice) recognition software. So, a kid comes in, sticks
their mug into a
camera and clicks a button that either says they are
coming or going. If
the picture can't be recognized, it is stored and flagged for human
identification. I have no idea how to do that though.
One other design problem is that we need some record of
who's in the
building that we can grab if there's a fire or other
where the sign-in sheet on the clipboard really shines.
Any brainstormy thoughts at all about pitfalls or
solutions would be
helpful at this point. Anyone else have a situation
similar to this?
There are many pitfalls, the biggest being smart kids - don't ever
underestimate the ability of a four year old to deceive.
Single scan (forget the in/out buttons, just have the current
will tell you just that something got scanned, so there is a
there. The kids can scan in and -not- enter or leave.
All the tokens not attached permanently can be exchanged ....
Can you do something of a bit futuristic nature, since the future will
happen soon? What I have in mind is "chipping" the kids with tiny RFID
chips. Works for my cats. I had to change the design from a
with the door mechanism to three scanners, so that I really know where
they are. I've seen cats and kids change their minds and back out after
opening the doors to go in -:)
Of course the above was somewhat in jest, but there is no good solution
without the use of biometrics, and even those can be fooled.
One inexpensive way is to count heads going in and out - web cam, simple
software. Make sure you push the video to an external server. In case of
an emergency, you'll now -how many- kids are in, to find out
you'd need to view the video. As far as I know, this is acceptable level
of data for emergencies.
Good luck, julius
The first thing I asked the school's director was if it would be OK to
chip the kids. This is exactly like herding cats, which, apparently,
you have some experience with. I've since realized that even chipping
the kids and/or video surveillance won't work. The kids at this school
have the option of playing outside if there is an adult out there to
supervise. This isn't considered "checking out". The kids really do
need to click or swipe something to signify their intention to
stay/leave. Since these kids can't be relied on to bring ID badges
every day and tattooing bar codes is a wee bit too futuristic, I'm
heavily leaning towards fingerprint swipers.
Can anyone recommend a linux friendly, affordable, USB, fingerprint
reader? One that can read through gloves, mittens, masking tape and
layers of assorted jams and jellies? My wife loves the idea of a hand
sanitizer station next to the finger print swiper, cut down on colds and
flus and track the kids all in one fluid motion.
Thank you everyone for your help thinking this through.
