Check start input
Confirm whether the chair accepts relay, pulse, serial, or custom board control.
Massage chair control
Massage chair payment controller for QR scan-to-start sessions.
Use QuLink when a massage chair, rest chair, or timed service device needs QR payment, timed relay output, app approval, and session status reporting.

Project fit
For timed service devices
Buyer signals
- Massage chairs and timed service equipment in malls, hotels, airports, or venues.
- Operators replacing coin or card modules with QR scan-to-start.
- Projects that need remote price/session control.
- Devices that should report online status and session results.
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
Timed control without a closed platform
QuLink can provide the machine-side board and QR payment flow, or connect to your own payment callback and backend.
- Machine interface
- relay, pulse, dry contact, UART/serial option
- Trigger source
- QR payment, app approval, wallet callback, or operator command
- Session control
- start, timed run, stop, query status, result callback
- Project mode
- venue rollout, retrofit control box, OEM controller
Workflow
From machine interface to API-controlled result.
Set session rule
Define price, duration, stop behavior, and payment reference.
Start after approval
QuLink triggers the chair for the allowed time.
Upload status
Your backend receives session 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/CHAIR-51/commands
{
"command": "start_session",
"source": "qr_payment",
"machine_action": {
"type": "relay",
"duration_ms": 900000
}
}
Project RFQ
Send a machine photo. We help identify the board, interface, and next test step.
Send the chair controller photo, payment module photo, voltage/wiring notes, target session duration, and estimated 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 this replace a coin box?
Often yes, if the chair accepts a pulse, relay, or compatible start signal.
Can QuLink handle different session durations?
Yes. Duration can be mapped from QR price rules, app selection, or server command.
Can it work with my own app?
Yes. Your app or server can approve the session and call QuLink.
