About QuLink

Machine-side control hardware for integrators who need real interfaces, real boards, and a clear sample path.

QuLink MDB and retail control board

Who we are

QuLink is the international hardware brand of Quhulian (趣互联), a team focused on unattended machine connectivity, control boards, and integration projects. QuLink Technology (Hong Kong) works with the Guangzhou engineering team to deliver board samples, API workflows, and OEM customization for export projects.

What we build

API-ready control boards and machine-side gateways for MDB vending, QR or payment-callback triggers, pulse/relay timed equipment, serial/RS485 data upload, lockers, charging sockets, laundry, amusement devices, and custom OEM machines.

What we are not

QuLink is not a closed SaaS platform, not a payment acquirer, and not a consumer app competing with your product. Your cloud, payment stack, pricing, and customer data stay yours.

How projects start

  1. Send a machine photo, board photo, or wiring note through the RFQ form or WhatsApp.
  2. We confirm the machine interface and suggest a board plus API workflow.
  3. Run a sample test, verify machine action and callbacks, then move to pilot or OEM rollout.
