The team was working on an idea that I bought to the table initially. Halfway through the hackathon, we scrapped the idea and started over. We still wanted to keep one aspect of our original idea which was QR codes. We thought about real world problems.

What it does

Allows children to scan a daily-changing QR code and sends a message to the parent/s that the child has arrived home from school safely.

How I built it

We built it in Swift, HTML, CSS, vanilla JavaScript, and Node.js.

Challenges I ran into

We changed our idea halfway through. We had trouble getting our Node server up and running and communicating with the Twilio API.

Accomplishments that I'm proud of

Getting the Node server up and communicating with Twilio.

What I learned

We learned how to work with QR codes, extended our knowledge of Swift, how to get a Node server up and running, and skills such as communication and planning out an idea extensively.

What's next for safeU

We will create affordable devices that serve the purpose of displaying the daily-changing QR code. We will also create apps for all smart home devices so that you can use what you already have instead of buying our device. We will implement these QR codes in areas like malls, playgrounds, movie theaters, etc. We will implement a GPS radius to the QR codes so that if the subject leaves the radius, you are notified.
