Putting a VCARD inside a QRCode is a perfectly fine way to transfer contact information too! This is just an alternative. After trying this technique of multiple QR scanning apps, I found a lot that didn't include this feature. However, every app I tried can launch the browser given an encoded URL. This solution allows the reader to inspect the data (visiting the url, email etc) before downloading the VCARD and polluting their contacts. There's no reason you can't self host this and add a URL shortener. I reason I choose not to embed such a feature is I wanted this to be 100% client side so I can develop this into a PWA. Hope I was able to clear up some confusion.
