Audio Confirmation Is Now Table-Stakes
QR payments scaled faster than the hardware around them. Merchants need an instant, hands-free way to confirm every transaction — without staring at a phone. The soundbox solved that. We took it further: an in-house designed, manufactured and software-controlled device family built for markets beyond India.
All-in-one QR soundbox — accepts payments from any UPI-enabled app and announces them aloud, instantly.
