How can an NFC battery's NFC functionality be used on Android devices? My Samsung Galaxy SIII comes with a battery with an Near Field Communications (NFC) label on it. Several earlier Android modles don't come with such a label on the battery. I would like to know what the NFC functionality on the battery enables Android devices and their OS to do with the battery.
Batteries labeled NFC come with the NFC antenna, without which it would be impossible for the NFC chip on the device to operate.
