My college is looking into attendance solutions in Canvas, specifically to allow for taking attendance in large classes. We need something that can incorporate scanning student ID cards or using something like a code that students submit. In addition, we need others outside of the course to be able to mark students as excused for illness or school business. So far, I'm looking at Aplus Attendance and Qwickly. If you've experienced both, which do you prefer and why? Is there another company I should definitely be checking out?
