Hardware für Gerätesteuerung

Ihre Plattform sendet Befehle. QuLink bewegt Maschinendaten und Aktionen.

Ihre Plattform behält

  • Cloud, App und Geschäftslogik
  • Payment Provider, Wallet, Checkout oder QuLink QR-Zahlungsworkflow
  • Kundendaten und Backend
  • Preise, Loyalty und Betriebsabläufe

QuLink Hardware übernimmt

  • Maschinensteuerungsboard und Konnektivität
  • MDB-, Puls-, Relais-, serielle und QR-Zahlungs-Triggerlogik
  • Gerätebefehle, Daten-Upload, Webhooks und Telemetrie
  • OEM-Board-Anpassung für wiederholte Deployments

Who this helps

Different buyers, one machine-side control layer.

QuLink is most useful when software, payment, or operations teams need a physical machine to react reliably after an API command or payment confirmation.

Machine operators

Retrofit existing machines with QR payment, remote start, telemetry, and fault reporting without rebuilding the full cabinet.

Who this helps

Payment apps / wallets

Keep the checkout and user flow in your platform; use QuLink for the machine-side trigger and result callback.

Who this helps

System integrators

Use API commands, webhooks, and board-level interface mapping instead of rebuilding MDB, pulse, relay, or serial behavior.

Who this helps

Machine OEMs

Move from sample validation to firmware, connector, enclosure, and board customization for repeat deployment.

Who this helps

Board selection

Start from the machine interface, not from a product name.

Most customers do not know the exact board model at first. Send the machine type, interface, wiring photo, or target action; QuLink will map it to a control board and API workflow.

OEM-Integration

Steuerungsablauf

Vom API-Befehl zur echten Maschinenaktion.

QuLink sitzt zwischen Ihrem Server und dem Maschineninterface. Ihr System sendet einen Befehl, das Board übersetzt ihn in MDB-, Puls-, Relais- oder serielle Steuerung und meldet das Ergebnis zurück.

Gerät identifizieren

Wählen Sie die Maschine per Device-ID, Route, Cabinet, Slot, Relaiskanal oder zeitbasierter Session.

Befehl senden

Ihr Server sendet einen signierten Befehl wie start_session, trigger_relay, unlock, dispense, stop oder query_status.

Maschine ausführen

Das QuLink Board übersetzt den Befehl in MDB, Puls, Relais, seriell, Unlock oder zeitbasierte Aktion.

Ergebnis melden

Das Board sendet Online-Status, Befehlsergebnis, Telemetrie, Fehleralarm, Vend-Ergebnis oder Session-Daten an Ihre Cloud.

QuLink QR-Zahlung

QR-Zahlung hinzufügen, wenn die Maschine Scan-to-Start braucht.

QuLink kann den QR-Zahlungsworkflow als Zusatzfunktion bereitstellen. Nach bestätigter Zahlung wird das Payment-Event in denselben Maschinensteuerungsbefehl übersetzt.

QR erzeugen

Erzeugen Sie einen QR-Code für Maschine, Produkt, Preisregel, Relaiskanal oder zeitbasierte Session.

Zahlung bestätigen

Nutzen Sie QuLink QR-Zahlung oder binden Sie Ihren eigenen Wallet-/Provider-Callback an.

Aktion auslösen

Nach Bestätigung startet, entriegelt, gibt aus, pulst oder betreibt QuLink die Maschine und meldet das Ergebnis.

How projects start

A low-friction path from machine photo to working sample.

You do not need a perfect technical brief on day one. Share what the machine should do, send, or report; QuLink can help identify the interface and next test step.

Send machine details

Machine model, board photo, wiring photo, coin/payment module, or target action is enough to begin.

Confirm interface

We check whether it is MDB, pulse, relay, serial, RS485, QR trigger, data upload, or a custom OEM case.

Test sample workflow

Connect a sample board, confirm command/API behavior, verify machine action and data callback.

Move to deployment

Adjust firmware, connector, enclosure, QR payment, or OEM board design for repeat deployment.

Maschinenkategorien

Für Geräte, bei denen Software eine physische Aktion auslösen muss.
