Key Metrics

Banks running a QR soundbox merchant acquiring program often face vendor lock-in. SoundHub solves this with a MQTT Solution for the acquirer's merchant ecosystem. Our low-latency messaging service allows acquirers to have a  multi-partner soundbox deployment support giving acquirers the flexibility to work with multiple vendors under a single integration layer.

How does SoundHub support a multi-partner soundbox deployment for banks?

SoundHub uses a low-latency MQTT protocol to ensure every UPI, QR, or card transaction triggers an instant payment notification at the point of sale. Unlike SMS-based systems prone to delays, MQTT delivers real-time callbacks directly to the soundbox so merchants hear the confirmation audio within milliseconds, reducing disputes from missed notifications.

How does SoundHub deliver instant payment notifications to merchants?

Yes. SoundHub is built with multilingual voice notification support, making it adaptable across linguistically diverse markets. Whether serving regional language speakers in India or Arabic, French, and Swahili-speaking merchants across the Middle East and Africa, the platform can be configured to deliver payment confirmations in the merchant's preferred language. As a white-label soundbox platform, banks can customise language defaults to match their specific merchant demographics and geography.

Does Mintoak SoundHub support multiple languages for voice notifications?

SoundHub provides a soundbox integration API that plugs into existing payment processing and merchant management systems- across UPI, SMS Pay, and POS channels. A unified device management layer gives banks visibility into device status, transaction callbacks, and merchant activation metrics, making it easy to scale a soundbox program without a heavy engineering lift.

How does SoundHub integrate with a bank's existing payment infrastructure?

SoundHub covers end-to-end soundbox device lifecycle management from ordering Soundbox through the merchant app, to activation, diagnostics, and replacement. Merchants complete soundbox onboarding entirely in-app, with no branch visit needed. Once deployed, real-time monitoring and remote troubleshooting reduce the operational cost of managing large soundbox fleets.
