comunication device - student - teacher

Me and Steven gathered the research for our persona’s and we have decided to create a device that teachers can use to keep track of there pupils on school trips. the device will be a two way device that allows the teacher to keep track of the children on school trips. the teacher will be able to communicate to the children by phoning from a hand set with a built in tracker and the children will be given magnetic bracelets in a variety of colours that has a tracker built in along with a GPS fitted within the bracelet.
