CardMe
By reading my ETH Global hackathon card with the camera, I can see my wallet id, my profile so far, my on-chain history, etc.
About
It is very difficult to tie on-chain history to real However, for example, some areas use business cards, cards that represent individuals, such as what company they belong to and what position they hold. I thought of adding those information to the Hackathon cards this time. By scanning their ETH Global card with a camera, users will be able to see additional information in AR, such as their wallet address and their profile.
How it's made
As for AR, I used 8th wall. This makes it easy to implement an AR interface. I also made it possible to read my ETH Global hacker card to get additional information about me. Basically, we import and use 8th in html. As for image recognition, we have created our own asset so that we can recognize ETH Global's hack cards when they are scanned.
