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 state ready)
will tell you just that something got scanned, so there is a problem right
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 single scanner
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 -which- kids,
you'd need to view the video. As far as I know, this is acceptable level
of data for emergencies.
Good luck, julius
