Every scan checked before the door opens.
Members scan their personal QR code — or tap in a PIN — and Gym Stack 360 checks their membership, plan, access window and freeze status before the barrier moves. No cards, no fobs, no arguments at the front desk.

QR, PIN or front desk — every entrance covered.
Each member carries a personal QR code in their app. No phone? They tap a PIN at the kiosk. Forgot both? Your front desk checks them in manually with one click — every entry logged with method, time and location.
- Personal QR codes rendered in the member app, validated in real time
- PIN entry for kiosks and members without their phone
- Manual override with staff attribution for full accountability

Know how full every location is — right now.
Live headcount for every site you run, aggregated per location and refreshed as members scan in. Spot crowding before members complain, staff your peak hours on evidence rather than memory, and compare sites side by side.
- Live headcount per location against the capacity limit you set for each site
- Hourly heatmap revealing your true peak patterns
- Multi-location view to compare utilization across sites
The door enforces your rules, so staff don't have to.
Frozen membership? Denied at the door — automatically, while the member keeps app access. Plan only covers off-peak hours? The access window enforces it, at 6 AM and at 6 PM, without anyone having to say no. Awkward conversations, eliminated.
- Freeze-aware — frozen members are blocked at check-in but keep their app
- Access windows by plan — off-peak, weekday or full access, per location
- The same rules everywhere — windows enforced at the front desk and at the turnstile alike

Not a log of who walked in — a barrier that opens.
Gym Stack 360 drives the hardware. Every lane has its own relay, pulsed the moment a scan checks out. The credential is a signed QR that rotates — single-use, dead in thirty seconds — so a screenshot passed around the car park opens nothing.
- A relay per lane, pulsed on a valid scan — the turnstile turns, not just a row in a report
- Rotating signed QR credential — every code is single-use and expires in 30 seconds
- Paired tablet kiosk that survives reboots and staff turnover — no login, no password on a sticky note
- Per-lane health monitoring and a test-pulse button, so you can prove a lane works before you open
