Problem Statement

  • Modern wallet app transaction procedure is very alien for people who barely know how to even use a phone
  • This is a huge roadblock when is comes to mass adoption of cUSD among small business owners
  • Present solution has way more friction when compared to using cash

Solution

  • An easy to use POS system where there is no need to even install an app. Everyone can start accepting payments within seconds
  • I implemented way to get transaction alerts without even opening your phone so that you can shift your focus on stuff that truly matters
  • The system is so effortless that everyone can use it

How it works

The system is divided into two parts

Web based payment kiosk Low cost payment alert soundbox
No nonsense payment requests through an intuitive interface. Just get started right away A smart speaker that makes automated sound alerts whenever the vendor receives any amount in their wallet using text to speech
Just enter your .celo/.soul name and the amount you want to receive and the kiosk will generate a custom amount QR code Uses very low cost hardware microcontrollers like Raspberry pi
The customer uses the QR code scanner from their phone and can pay through their celo wallet app The smart speaker uses Quicknode’s Quickalerts service to monitor wallet transactions
No need to check your wallet every after every transaction so that you can focus on stuff that truly matters
