Designed for modern retail environments, the Mantra MS20 provides instant voice notifications for payment transactions processed through compatible QR code and UPI payment applications. When a payment is successfully received and verified by the connected payment platform, the device announces the transaction notification through its integrated speaker. This allows merchants to identify incoming digital payments without constantly checking their smartphones.

The MS20 features a 6-digit 7-segment LED display that can show received payment amounts when enabled by the supported application and configuration. This visual information, combined with audible transaction announcements, improves payment transparency and helps merchants monitor their daily transactions more efficiently.

For reliable communication, the Mantra MS20 supports 4G LTE and 2G cellular connectivity, with an optional 2.4GHz Wi-Fi connection. Its built-in Micro-SIM card slot allows the device to connect to compatible cellular networks, making it suitable for commercial locations where dependable internet connectivity is required.

Powered by an ARM Dual-Core Cortex-A5 processor running at 500MHz, the MS20 provides a dedicated hardware platform for payment notification operations. It comes with 16MB RAM and 24MB Flash memory to support its firmware and device functionality.

The device incorporates a powerful 4-ohm, 3W speaker with adjustable volume and approximately 85dB-class sound output, helping merchants hear payment notifications in busy retail environments. Its adjustable audio level allows businesses to select a suitable volume according to their surroundings.

Another important feature is its 2000mAh rechargeable Li-ion battery, which supports portable operation and reduces dependence on continuous electricity. The powered USB Type-C interface provides convenient charging, while dedicated LED indicators help merchants monitor battery and network connectivity status.

The Mantra MS20 also supports Over-the-Air (OTA) firmware updates, including DFOTA and audio file updates. This allows compatible service platforms to maintain device software and update notification audio remotely, helping simplify ongoing device management.

With its compact dimensions of 112 × 100 × 73mm and an approximate weight of 280g, the Mantra MS20 can be conveniently placed on retail counters, payment desks and service points. Its integrated design makes it suitable for businesses looking for a dedicated digital payment notification solution.

For the Bangladeshi market, the MS20 can be considered for merchant QR payment applications subject to the availability of an authorized local payment platform and compatible backend integration. Support for bKash, Nagad, Rocket, Bangla QR or other local payment networks must be confirmed with the respective acquiring bank or payment service provider before deployment.

Whether used in a grocery shop, supermarket, restaurant, pharmacy or commercial establishment, the Mantra MS20 Dynamic QR Sound Box provides a convenient way to improve payment awareness, reduce manual verification and make digital payment interactions more transparent.
