title: Share Wifi credentials via NFC tag without special apps
body: <p>I am looking for a way to create a NFC-tag that shares the wifi credentials of my network without my guests having to have any special NFC apps on their phone (other than whats coming with the phone).
  I have been looking at apps and services like NFC Tag Writer, WifiTap, NFC Task Launcher and NFCLabels.com, but it seems to me like it I would need to have the apps on the guest mobile as well to be able to use it, but I am not able to test it as I only have one NFC-enabled phone available. (Yes, I know, twisting my brains for nothing, but heck, weird behaviour is nothing new...)</p>
  
  <p>My closest clue is that WifiTap states that:</p>
  
  <blockquote>
    <p>The app processes URIs in the format of wifi://[network ssid]/[wep|wpa|open]/[network key] </p>
  </blockquote>
  
  <p>If this is actually universal this would mean that I could do what I what I want to, but I have not found any confirmation on this. So, how could what I want be done and am I on the right track with the clue from WifiTap?</p>
