Sensors to detect attendance of students in class.

Sensors can detect a specific person if that person is uniquely tagged, perhaps with an RFID tag, for example.  However, a tagging system can be defeated if the tag is not carried consitently, if the tag is shielded from RF, or if someone else carries the tag in a purposeful attempt to game the system.  Biometric identification based on facial recognition is getting much better, but is still expensive and the ethical issues are huge and complex.  A low tech solution is to have students hand in signed work at the end of every class.  If the work is derived from topics discussed during the class, then spoofing is pretty difficult.

I think the best approach to managing attendance is to make sure classes are engaging, relevant, and respectful of the needs of the learner.  If those aspects are addressed then worrying about attendance should be pretty much a non-issue.

Sir,

          I have studied about RFID technique,but there are some loopholes in this process.I think that if a person is not interested to come to college he/she can send his/her id card with his friend so he/she can get attendance.Even face detection is also not possible if there are twins in the class.So i need a better technique for this.

When I was at school we had this new thing called a class register.

Instructorman has already made a really good point about engaging with the class.

It seems like this technology is trying to solve a problem that doesn't exist.

I'm sure this is  a case where traditional technique works best. At the end of the year you have exams which are conducted under carefully controlled conditions. If the student passes does it matter if he learned by reading, attending lectures or hanging out in bars ? (NB this last approach is not usually successful)
