The term ‘i’ represents intelligence, while ‘Swara’ denotes sound. The iSwara SoundBox is a payment notification device designed to provide real-time audio alerts for every successful transaction. It supports multiple payment channels like UPI payment, Card swipe, NFC, etc. and offers multilingual notifications to ensure clarity and convenience for both merchants and customers.
A static QR SoundBox uses one fixed QR code (merchant QR) for all customer transactions. In contrast, a dynamic QR SoundBox generates a unique QR code for each individual payment. Both are convenient in their own ways—static QR SoundBoxes are ideal for small businesses, while dynamic QR SoundBoxes are better suited for larger entities such as shopping malls.
The iSwara SoundBox API is a developer-friendly interface that allows seamless integration of SoundBox functionality into merchant applications or third-party systems. Developers can use it to enable instant transaction alerts, manage devices, customize multilingual notifications, and track payment records, making it easy to embed SoundBox capabilities into digital payment ecosystems.
The iSwara SoundBox connects to the merchant’s account via SIM or internet and links with the QR code. Once a customer makes a payment, the transaction is verified in real-time and the device instantly announces the payment amount and status through a clear audio alert in the selected language.
Yes. A single iSwara SoundBox can be configured to support multiple merchant QR codes & i.e, Dynamic Soundbox, making it convenient for businesses with multiple cash counters or product lines.
Businesses and resellers can partner with iSwara by contacting the iServeU sales team. iServeU offers bulk procurement options, reseller partnerships, and integration support to ensure smooth onboarding for merchants at scale.
Yes, merchants can use their own SIM card. However, iServeU provides pre-enabled SIMs with its SoundBox devices to ensure hassle-free setup, uninterrupted connectivity, and faster transaction updates.
The iSwara SoundBox supports multilingual announcements, including +12 major Indian languages such as Hindi, English, Odia, Bengali, Tamil, Telugu, Kannada, Malayalam, Marathi, Gujarati, and Punjabi. Additional language support can be enabled based on merchant requirements.
No. The iSwara SoundBox only announces successful transactions to avoid confusion. Merchants can check pending or failed transactions through their linked payment app or merchant portal.
