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.
