About

The problem it solves # 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 crypto payments 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 address or .eth 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 mobile wallet app | The smart speaker uses Quicknode’s Quickalerts service to monitor wallet transactions | |
