With windows phone you always have to confirm something onscreen after using a NFC tag.
There's also nog possibility to make automatic switches with NFC. For example, with android you can make NFC tags that automaticlyswitch your bluetooth on or off. With Windows Phone the best you can do is make a NFC tag that opens your bluetooth settings, but you still have to switch bluetooth on/off onscreen.
NFC combined with windows phone is very very limited.
