You’ll be surprised at how fast and smooth it is. Hold it in place for an instant and you’ll get your result. Click on the QR button and show the camera some QR code to scan.

We’re not going to build that ourselves, because there are some great libraries out there doing this for us, so we don’t need to reinvent the wheel for our current purposes. Our QR code reader will need some HTML and JavaScript but most importantly, a JavaScript library capable of interpreting the QR code.
