SV01–SV05: one cloud platform, five payment devices.
The SonicVolts SV series is a family of cloud-connected UPI soundboxes and SmartPOS devices designed for India-scale deployments. From entry desktop units to pocket clip-ons and a full SmartPOS with printing, each device plugs into the same SonicVolts cloud backend.
All devices are designed and validated in India using India-made enclosures, local assembly and full-cycle testing, while leveraging qualified EMS partners for SMT and core electronics.
Compact desktop soundbox for everyday merchants.
SV01 is a compact, desktop cloud-connected payment soundbox designed for high-volume rollouts to kirana stores, micro-merchants and local service providers. It plays clear voice confirmations for successful digital payments in multiple Indian languages, helping reduce disputes at checkout and building trust between merchants and customers.
The device is engineered for reliability, low total cost of ownership and easy deployment, with static UPI QR flows optimised for everyday, repeated payments.
- Static UPI QR flow for simple, repeat transactions.
- Rechargeable Li-ion battery with DC input for continuous operation.
- High-efficiency speaker tuned for voice clarity in noisy shops.
- Battery capacity and functional checks for every unit before dispatch.
Upgraded soundbox experience for flagship counters.
SV02 builds on the SV01 platform with a premium compact enclosure, richer audio profile and extended battery life. It is ideal for flagship kiranas, QSRs and franchise outlets that want hardware which looks as good as it sounds.
Internally, it stays aligned with the SonicVolts platform, so banks and fintech partners can deploy SV01 and SV02 as a mixed fleet without changing backend integrations.
- Refined industrial design for brand-conscious outlets.
- Enhanced speaker tuning for pleasant, clear voice prompts.
- Battery sized for longer unplugged operation at busy counters.
- Common firmware and cloud backend shared with SV01.
Pocket-sized static QR soundbox with clip-on.
SV03 is a pocket cloud soundbox with a built-in clip designed for belt or pocket attachment. It brings the same SonicVolts payment confirmation experience to people who are constantly on the move.
Static QR-based flows make it simple for delivery agents, field sales staff and roaming vendors to accept payments without needing to manage transaction-specific QR codes at the counter.
- Clip-on mechanical design tested for belt/pocket attachment.
- Static UPI QR flow aligned with existing merchant QR setups.
- Optimised Li-ion battery sized for a full working day of mobile use.
- Speaker tuned for near-field clarity without being excessively loud.
Dynamic QR soundbox with on-device display.
SV04 extends the pocket category with a built-in display that can show a fresh dynamic QR for each transaction. This is suited for secure field collections and cases where reconciliation per payment is critical.
The device continues to offer audible confirmations and cloud logging, making it easier to match collections against settlement reports and backend dashboards.
- Transaction-level dynamic QR display on the device.
- Cloud-linked for secure authorisation and reconciliation.
- Designed for field collections and higher-value mobile payments.
- Integrates with SonicVolts cloud alongside SV01–SV03.
SmartPOS device with integrated soundbox and printer.
SV05 combines a soundbox, POS touchscreen and thermal printer into a single compact unit. It is built for supermarkets, restaurants and service centres where merchants expect printed receipts alongside clear voice confirmations.
The device supports both static and dynamic QR flows and can be integrated into existing acquiring stacks as a full SmartPOS terminal with SonicVolts-managed audio confirmations.
- All-in-one SmartPOS: screen, soundbox and thermal printer.
