A CodeZ QR is returned to the desktop and printed on an MFP or at home.
As students come to school the clickable paper is seen by a PC camera or a smart phone.
Then you do it every computer lab.
Then you do it in every class as the student arrives.
Then you do it in Clickable Print teaching materials.
Meanwhile, the Cloud knows who went where and who did what and when they did it.
