Pool table timer control
Pool table timer controller for QR payment and timed game sessions.
Use QuLink when a pool table, billiard table, game room, or table-service device needs QR payment or app approval to start a timed session, control lights or power, and report session results.

Project fit
For pool halls, game rooms, and timed table services
Buyer signals
- Pool tables that need QR payment or app start.
- Game rooms with coin, token, or manual timers.
- Operators that want remote session control and usage data.
- Venues that need lights or power switched with the timer.
What to send first
- Machine photo or existing board photo
- Interface or wiring note if available
- Target action after API command or payment
- Whether telemetry or data upload is required
Not the right fit if
- You only need a pure payment acquiring account and no machine-side control.
- There is no physical machine action after payment, booking, or API approval.
- The project has no machine photo, board photo, wiring note, or interface clue yet.
Integration model
Payment approval starts the table timer
QuLink activates a relay for the table, light, or power circuit, runs the session timer, and reports start, end, extension, and fault events.
- Machine interface
- relay output, dry contact, pulse input, serial option
- Trigger source
- QuLink QR payment, app approval, operator panel, or server command
- Session control
- start, timed run, extend, stop, query status
- Data returned
- session start/end, duration, fault, online/offline, usage log
- Project mode
- coin-timer retrofit, venue rollout, OEM controller
Workflow
From machine interface to API-controlled result.
Map price to time
Define price, duration, extension rules, and stop behavior.
Start the session
QuLink activates the output after payment or server approval.
Report the session
Your backend receives start, end, extension, and fault events.
API example
A clear server command or webhook for the machine-side action.
The exact command fields depend on machine interface, firmware profile, and whether payment or your own app triggers the action.
POST /v1/devices/POOL-08/commands
{
"command": "start_session",
"source": "qr_payment",
"reference_id": "POOL-ORDER-008",

Project RFQ
Send a machine photo. We help identify the board, interface, and next test step.
Send the timer or relay photo, table and light wiring, price and duration rules, target payment flow, and venue quantity.
A good first message
If you are unsure about the exact interface, send what you have. Photos often answer more than a long spec.
- Machine type and target country
- Machine photo, board photo, or wiring photo
- Action after payment or API command
- Need data upload? expected quantity?
Fastest first step
- Send a machine photo
- Describe the action after API or payment
- Tell us if data upload is needed
FAQ
Questions buyers usually ask before a sample test.
Can it replace a coin timer?
Often yes if the existing timer or table controller accepts a relay, pulse, or dry-contact start signal.
Can it control lights as well as the table?
Yes when a suitable relay channel and wiring are available. The sample test confirms the circuit.
Can a session be extended?
Yes. Your app or backend can send an extension command if the project allows it.
Can it report usage?
Yes. Session start, end, duration, fault, and online status can be uploaded.
