The single member, many branches problem
When a member walks into your second branch, three questions need to resolve in under a second: are they paid up, do they have access to this branch, and what membership tier are they on (which determines pool/sauna/PT-room access)?
Most chains hack this with a manual call to head office, or by giving every member a generic "all-access" pass and hoping for the best. Both approaches cost money. The first burns staff time at the door, the second leaks premium-tier access to value-tier members.
GymViz solves it by tying every biometric profile, every payment method, every member preference to a single GymViz member ID that works at every device in every branch. Tier rules are enforced at the device, not at the front desk. The member experience is "I am a member of this gym, I scan, I am in." The owner experience is full visibility without manual gymnastics.
