Consistent with the previous leaks, it looks like Google's Android team has put some effort into easier printing from Android devices beginning with KitKat.
Shown above is an option to turn on Cloud Print, presumably the Google service launched earlier this year, which enables print jobs to be sent from tablets, phones and notebooks over the web.
The settings icon has changed from 4.3, and in this version Google looks to have implemented a Tap and Pay feature. Exactly what Google has here isn't known yet, but it would appear to suggest better support for NFC-based payments. Interestingly, Google recently opened up Google Wallet to all Android devices running 2.3 or higher, even on hardware without NFC support.
NFC payments built-in to KitKat?
Google's Tap and Pay isn't enabled here so it's hard to say if it's working or not.
