How do I use a barcode scanner in a web application?

You can capture the keypresses that the barcode reader sends with JavaScript. Add an event listener to the window or document object to capture any keypresses anywhere in the document. Check the incoming characters for one which signals the end of the barcode (probably a new line).

Can you scan a QR code from a website?

How do you scan a QR Code from a website? Just as you would scan a printed QR Code. Launch either your mobile phone's camera or open your QR Code scanning app, point it at the QR Code and voila! Instant access to your favorite brand's information.

Can a barcode direct to a website?

Bar codes have no direct connection with web sites.
