virtual-key VS HADWIN

Check this repo: GitHub

Hi everyone, I would love to share our latest project built with Flutter. We've been developing it for a month, and already have some stunning results! **Our goal is to replace a regular key with a system that will open a lock by reading a QR code from our smartphone. The system is based on Raspberry, but we would like to create it on a budget i.e. ESP32, so every one of you could recreate it in the garage.** *The whole project is open-source so feel free to check it out! We would be grateful for every advice and tip.* **How does it work?** 🔑 • ⁠Generate a QR code in the mobile or website app • ⁠Scan QR with a code reader • ⁠The gate opens for 30 seconds• ⁠The device sends an Event log to the website **You can play around at our website** [Key Manager](https://keymanager.theiotproject.com) **or visit our** [Blog](https://theiotproject.com/) **Examples of usage:** • ⁠Airbnb and Booking.com systems • ⁠Regular home/office locks. Let’s put a key in past. • ⁠You can give remote access to a lock by sending an invitation or the same code • ⁠The system will inform you about the exact time the employee entered work and left • And of course: you can mount it on your fridge to keep beer safe (useful in a college!) Please remember: we are students and most of these things are new for us. We are still learning and making mistakes. I hope I interested you a little and you will follow our work. 🤝 **For more information about the project as well as how to build it yourself, please follow us at** [**GitHub**](https://github.com/theiotproject/virtual-key)

Every application needs a payment service or a transaction interface to make payments while signing up for a subscription. Through HADWIN, one can learn various fundamentals and skills like design patterns and state management/nested state management with the Provider pattern. Also, how to fetch data from servers with restful API to connect the app to backend services.

I have been working on a prototype of a fund transfer app called HADWIN, actually completed and released version 1.0.0 ... i guess we can call it progress 😅 I have built it with Flutter... but scalability is an issue so this month I will probably be working on making it scalable with this server I have been building with python-flask other than that debugging most probably.
