Saturday, April 18, 2020 - A Convenient Way to Take Attendance for Large Classes is a new service that could be helpful whenever we return to having classes in-person instead of virtually. is a system that lets students check themselves in for your class.

With the system you simply project a QR code and your students scan it with their phones to check themselves in. Students who don't have a smartphone can check in by using a corresponding check-in code that is displayed next to the QR code. The QR code and check-in codes are dynamic which means they change from class to class so that students have to be there in class to get the correct code.

Applications for Education
I tested and found it to be a easy to use. I can see it being helpful to those who teach large classes.

There are some issues that will keep me from using it with my classes. First, I know all of my students by name and face so I can take attendance in less time than it would take to project the QR code and get students to scan it. Second, even if students use use the numeric check-in code they still have to verify their phone numbers. For those two reasons I don't see it being a tool that K-12 teachers will use, but it could be a solution for taking attendance in university classes and for conducting check-ins for large conferences.
