Key Highlights

Instant Voice Confirmation for Every UPI Payment

MS20 gives merchants instant, audible confirmation of every UPI transaction - no more checking phones or screens. Loud, clear, and connected over 4G LTE for reliable operation in any retail environment.

85dB Loud Speaker

4 Ohm | 3W | Adjustable

4 Ohm 3W speaker delivers 85dB clear payment announcements even in noisy retail environments. Volume is adjustable so merchants can set it to suit their environment - from a quiet café to a busy food stall or a loud market.

4G LTE + 2G Cellular

LTE-FDD/TDD | Micro SIM

Always-connected over 4G LTE (FDD: B1/B3/B5/B8, TDD: B34/B38/B39/B40/B41) and 2G EGSM900/DCS1800 fallback with 1* Micro SIM slot - ensuring reliable payment notifications even in areas with weak 4G coverage.

6-Digit LED Display

7-Segment | Amount Display

6-digit 7-segment LED display shows the received transaction amount at a glance. Two independent LED indicators show battery status and network connectivity in real time - so merchants always know the device is ready to receive payments.

OTA Updates

DFOTA | Music | NTP Sync

Device firmware and audio notification files update over the air (DFOTA) - no physical service visits needed. NTP time synchronization keeps all transaction timestamps accurate for reconciliation and reporting.

2000mAh Battery

USB-C | DC 5V/1A | Li-Ion

2000mAh Li-Ion rechargeable battery via USB-C (DC 5V/1A) powers the MS20 throughout a full merchant business day. Compact 112*100*73mm form factor and 0.28kg weight make it easy to place on any counter or carry anywhere.
