The NFC area is right below the cameras.
Let us not forget that the phone is with aluminium back and if the NFC tags that it has to read are under a cover (eg under the plastic casing) of the device, it may not read properly. The distance to the tags needs to be much closer.
Anyway, The tags are only used in this case to identify the devices for Bluetooth pairing. So you can search for the BT devices and pair this way.
