We have a school management system which is built on ruby on rails. It
an attendance system where attendance can be marked manually and SMS
notifications are sent to parents for absent students… Every student
profile has a unique Hardware ID which is linked to their student ID and
Our hardware devices will be transmit this hardware ID to a set port on
server from where it has to be read to get student information and then
mark attendance accordingly.
Sample ruby code to communicate with the database to get student
information from hardware ID and to mark attendance will be provided.
You have to develop a plugin for the student management system which
all this and also sends SMS for in and out time of the students
on the time of the hardware id received on the port.
An easy api platform will also be provided where html and ruby code can
easily tested and implemented.
