The QR Code Extension is a free Chrome add-on developed by Beaconstac. It allows users to generate a QR Code for the current page and scan a QR Code using the webcam. With just a single click, users can generate a QR Code from the URL of the current tab. The generated QR Code is displayed inline in a small popup.

One of the key advantages of this extension is that it does not require any special permissions, such as access to your tabs and data. It is only loaded when you click on the button, ensuring that it does not consume unnecessary memory or impact performance when not in use.
