Place the code well
Doorway or reception — not the middle of the mat. One scan habit per visit.
Always have a fallback
Dead phones happen. Coach manual and kiosk keep the ledger complete.
Explain the why
Members accept QR faster when they see progress and fair promotions downstream.
What if QR feels too techy?
Start with kiosk for a week, then add member QR for those who want speed.
Can guests check in?
Model drop-ins as members or session guests according to your policy — avoid anonymous ghosts in the data.
