The Challenge

Walk-in guests can't access the space without staff present to handle payment
Per-minute billing requires manual time tracking and error-prone calculations
Membership and drop-in systems are separate — double management overhead
No way to auto-checkout guests when the facility closes for the night

How UnlockOS Helps

Guests scan QR or open LINE — select a plan group and check in instantly
Usage-based billing calculated automatically from entry to exit, with daily caps
Plan groups let guests choose between drop-in, flat rate, or one-time pricing
Auto-checkout at closing time with automatic Stripe settlement
