I tried to use archiving for absent students, and it works, the only downside is that the student's card becomes available again and could thus accidentally be given to a new student that is added to the class. If the original card is still available, the archived student will get it back upon unarchiving, but s/he will get a new card when the card has been given to someone else in the meantime.

Would it be a solution to archive that student temporarily, and activate the card again when the student is back in class?

I wholeheartedly agree, you got my last 3 votes. I presented Plickers yesterday to interested colleagues throughout our university, and this was the question that was most often asked: can I use it in a large auditorium, with 100-200 students? By increasing the grid from 5x5 to 6x6, it should be possible to make many more unique cards, although the requirements for the scanning device (tablet, smartphone) would probably be higher (high camera resolution to reach the last rows, speed of image recognition). Maybe simultaneous scanning with multiple devices or webcams could be implemented.

Android users can scan in portrait or landscape mode, and we’re currently working on this for iOS users. It should be available in a future app update! Hang in there!

I've checked, and the percentage correct answer, both in the app and in the report, is based on the number of actual votes, not on the total number of students in a class.
