We had a church sign up for Churchteams the other day because they saw what we call "All Check" in action at another church. The big idea with All Check is that you can use it to check everyone in to everything they are involved in on a Sunday morning.
Not only is it used to check in kids and print out security tags, but all your students and adults use it as well to check-in to their small groups, serving teams, and worship. Literally, everyone check-in to everything.
