title: How to launch app using NFC tag on Windows Phone 8?
body: <p>I got Windows Phone 8 device, few NDEF formatted NFC tags and I'm wondering, is it possible to implement app launching on my WP8 using these tags? I've read thoroughly this article about <a href="http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj662937%28v=vs.105%29.aspx" rel="nofollow">URI schemes for launching built-in apps for Windows Phone 8</a>, but I haven't found any link related to actual launching of 3rd party apps. I can launch various settings screens, or browser, email, SMS...</p>
  
  <p>What is more interesting, that there are at least two NFC tags on WP Store that can "write tags for launching apps", I've tried them, but the launching is just not working.</p>
  
  <p>So the question is: is it possible to store on NFC tag information for launching any 3rd party app on WP8? If yes, what is the format of such URI scheme and how to write it to a tag using WP8?</p>
