Confirm wiring
Check coin input, start signal, relay channel, power, and session duration.
Laundry QR payment
Laundry machine QR payment controller for timed start and session upload.
Use QuLink when washers or dryers need QR payment, app approval, relay start, pulse simulation, timed sessions, and status reporting to your backend.

Project fit
For laundry retrofit and operator rollout
Buyer signals
- Washers and dryers that need payment-to-start conversion.
- Coin-op machines being upgraded to QR payment or app control.
- Operators that need session result and online/offline status.
- Projects needing sample tests before larger deployment.
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
Integration model
Turn approval into timed machine output
QuLink handles relay duration, pulse output, start signal, stop behavior, and session callbacks while your platform keeps pricing and customer flow.
- Machine interface
- relay output, pulse input, dry contact, sensor input, serial option
- Trigger source
- QuLink QR payment, app approval, operator panel, or server command
- Data returned
- session.started, session.completed, fault, online/offline
- Project mode
- laundry room retrofit, operator rollout, OEM control box
Workflow
From machine interface to API-controlled result.
Define payment rule
Map QR payment or app approval to one cycle or timed session.
Start machine
QuLink sends pulse or relay output and tracks the session.
Report session
Your server receives start, completion, fault, and status 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/WASHER-18/commands
{
"command": "start_session",
"source": "qr_payment",
"machine_action": {
"type": "relay",
"channel": 1,
"duration_ms": 2100000
}
}
Start the project
Send the first machine details before writing a full spec.
Send the washer/dryer photos, coin input wiring, voltage notes, session length, and payment workflow.
Useful first message
- Machine type and target country
- Machine photo, board photo, or wiring photo
- Action after API command or payment
- Data upload and estimated quantity
FAQ
Questions buyers usually ask before a sample test.
Can QuLink start an old coin laundry machine?
Many coin-op retrofit cases can be handled by pulse simulation or relay output after wiring is confirmed.
Can one controller handle several machines?
That depends on channel count, wiring distance, and isolation requirements. We can evaluate from photos and wiring notes.
Can it upload laundry status?
Yes. Online status, session result, fault, and telemetry can be sent to your server.
