SunoPaisa: Eradicating Payment Fraud with Offline-First Alerts

The Hidden Cost of Fake Screenshots

Digital payments have revolutionized the way merchants do business. However, as cashless transactions have grown, a new type of fraud has emerged: the fake payment screenshot.

In busy retail environments, especially in areas with slow or unreliable 3G internet connections, merchants don't have the time to log into their banking app to verify every single 500 Rs transaction. Scammers exploit this by showing fraudulent payment confirmation screens.

By the time the merchant realizes the money never arrived, the scammer is long gone.

The SunoPaisa Solution

We built SunoPaisa at the VoxaGrid Lab to completely eradicate this problem.

Instead of forcing the merchant to manually verify payments, SunoPaisa does the heavy lifting automatically and instantly.

Instant Audio Alerts

The moment a customer sends a payment, SunoPaisa announces the exact amount out loud in the local language. The merchant doesn't even need to look at their phone. If they hear the announcement, the payment is confirmed.

Works Without Internet

The most crucial feature of SunoPaisa is its offline-first architecture.

Unlike other FinTech applications that rely entirely on cloud servers to process notifications, SunoPaisa operates entirely on the merchant's device. This means that even if the merchant's internet goes down, or they are in a dead zone, the audio alert will still trigger the exact millisecond the banking SMS arrives.

Absolute Privacy

Because the processing happens locally on the smartphone, sensitive financial notifications are never uploaded to our servers. Your business data remains your business data.

Empowering Merchants

SunoPaisa is more than just an app; it's an infrastructure layer that protects the hard-earned money of small business owners. With SunoPaisa, merchants can focus on serving their customers with the absolute peace of mind that every transaction is instantly and securely verified.
