Most revenue leaks are small and repetitive: one slot that will not eject, a QR that opens the wrong flow, a cabinet that drops offline every afternoon when the venue router reboots. A simple triage sheet saves your team hours and keeps venue managers on your side.
Common pattern: "Won't charge" tickets often trace to oxidized pogo pins or weak LTE/Wi‑Fi — not dead packs. Clean contacts and check signal before you swap hardware.
Hardware checks (safe for field staff)
- Confirm mains power and time sync
- Inspect contacts and slot rails; clean per your SOP
- Follow vendor unlock steps for jams — no forced pulls
- Retest QR with a second phone; verify sticker version
Software checks
- Payment success vs cabinet release in logs
- Venue binding and pricing profile on the server
- Pending OTA — schedule during low traffic
When to escalate
Call the supplier when a slot fails after two clean cycles, when you smell heat or see swelling, when reboot loops persist, or when payment mismatches need cloud logs to reproduce.
