QRanibal the Scanibal

This is a simple Flask web app I wrote to scan QR codes and extract DEV EUIs using the device's camera. It serves a basic HTML page, accesses the camera via getUserMedia, and repeatedly sends the captured frames to the Flask /process_frame endpoint for server-side decoding.

Please note that this is a very basic proof-of-concept application. In a real-world scenario, you would likely want to handle decoding on the client side but I wanted to test out this python library I found that uses an advanced object detection model.

Therefore, disclaimer: Use at your own risk—this code is not production-ready.
