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.
Payment apps / wallets
Keep the checkout and user flow in your platform; use QuLink for the machine-side trigger and result callback.
Who this helpsSystem integrators
Use API commands, webhooks, and board-level interface mapping instead of rebuilding MDB, pulse, relay, or serial behavior.
Who this helpsMachine OEMs
Move from sample validation to firmware, connector, enclosure, and board customization for repeat deployment.
Who this helpsBoard 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.

Integração OEMFluxo de controle
Do comando API para uma ação real da máquina.
A QuLink fica entre seu servidor e a interface da máquina. Seu sistema envia um comando, a placa traduz para MDB, pulse, relay ou serial, e reporta o resultado.
Identificar dispositivo
Selecione a máquina por device ID, rota, gabinete, slot, canal relay ou sessão por tempo.
Enviar comando
Seu servidor envia um comando assinado como start_session, trigger_relay, unlock, dispense, stop ou query_status.
Executar máquina
A placa QuLink traduz o comando para MDB, pulse, relay, serial, unlock ou ação por tempo.
Reportar resultado
A placa retorna status online, resultado do comando, telemetria, alerta de falha, resultado vend ou dados de sessão.
Pagamento QR QuLink
Adicione pagamento QR quando a máquina precisar de scan-to-start.
A QuLink pode fornecer o fluxo de pagamento QR como capacidade adicional. Depois da confirmação do pagamento, a QuLink transforma o evento no mesmo comando de controle da máquina.
Gerar QR
Crie um QR para máquina, produto, regra de preço, canal relay ou sessão por tempo.
Confirmar pagamento
Use pagamento QR QuLink ou conecte seu callback de wallet/provider se já tiver stack de pagamento.
Acionar máquina
Após a confirmação, a QuLink inicia, destrava, dispensa, pulsa ou executa a máquina e reporta o resultado.
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.
Categorias de máquina
Para equipamentos onde o software precisa acionar uma ação física.
Vending e Smart Retail
MDB vend, QR vend, telemetria, evento de estoque, resultado de dispensa.
