It doesn't limit NFC, it just means that someone (or lots of someones) need to write some software to do it. The biggest issue is that everyone needs to agree on how to do it, otherwise you'll need to install your special software onto someone else's phone to get it to work.

I assume the linkedin app monitors for the URL or the website is able to launch the app. Which is one of the suggestions i made above. Start trying to convince the other social media groups to do it?

I just used the outer tag to send people to my websites contact page which works well for me.
