Challenge
Attendance dipped after week three, and too many students failed to re-enrol for the next term. Admin emailed PDFs of timetables that went stale. Parents of younger students had no live view of remaining lessons.
Strategy
Each student (or parent) installed a Wallet Pass with course name, remaining lessons, and the next class time. Missed-class pushes went to the student, while early-bird next-term offers went to the payer. A simple attendance stamp on the pass made progress visible without a learning-management login.
