I want to design a system that takes attendance at school.
Students arrive at their class in the morning, use their fingerprint to log in their attendance.
There would be hardware at the classroom that can read a fingerprint, send info over wireless net, an LED light that can flash either red or green, a small LED screen that can display a text alert.
This info is then sent to the administration office where the class attendance is kept.
If a student is absent (or not fingerprinted in) a sms is sent to parents.
The students would also fingerprint out and in when they leave the classroom. If they are not back in 10 mins (needs to be a settable parameter) the light flashes red and a message appears on unit eg. 'Tom is not in the classroom'.
The fingerprint scanner needs to be a portable device, battery powered, a green& red led light with an LED screen for plain text and wifi connectivity.
A simple database needs to be connected to the system.
It needs to be able to record attendance initially and then the comings and goings of students throughout the day.
If a student does not attend initially then an alert needs to be generated and an sms sent out to contact details attached to that child's file.
Seems to be rather basic database but getting lots of expensive quotes.....
