BJJ class attendance is currently tracked via physical cards that need to be marked each class. This process is very error prone and is one extra thing for the coaches to spend their time on. It seems more logical to track BJJ attendance on a digital card that is automatically updated after the student registers for class and checks into the gym.

One added benefit would also be that people who are not taking classes, ie. parents of students, won’t be altering student attendance by marking the cards when the coaches aren’t looking.
