How it works

  1. User Scans the QR Code: First, the user scans the QR code on the vending machine.
  2. Event Trigger: Second, the QR code link triggers an event on the cloud server where the MQTT Broker is running.
  3. Message Transfer: At this point, the MQTT Broker sends a message to Qiba’s device with credit information, which then communicates with the vending machine via MDB.
  4. Product Dispensing: Finally, the machine dispenses the product, and Qiba’s device sends a confirmation to the broker, which can also notify the customer’s web app.
