NFC is about standard on all high-end Android smartphones nowadays and the Samsung Galaxy S III has it, and so does the Note II. However, Samsung implemented the functionality differently on the S III than on the Note II. While the Galaxy S III has the antenna inside the battery itself the Note II has it on the battery cover touching the phone via two contacts.

The Samsung Galaxy S IV appears to follow the Galaxy S III route, if the battery on the leaked Chinese version is any indication. We’ve just learned that said battery is rated at 2,600mAh and the Near Field Communication call-out on the battery is a clear indication that Samsung is maintaining the principle present on the S III (and not going the Note II way with the NFC antenna on the battery cover).
