I really do think that it's a card swipe reader for unlocking doors via either card, iPhone NFC or maybe BT. Probably for the new Apple HQ.
The FCC test diagram even references that the EUT (Equipment Under Test) has a "Door SKU":

It also mentions testing NFC in portrait, landscape and flat orientations, which could correspond to mounting it differently on walls or tables.
Surely this is for a car keyless entry system then? DC supply, NFC. Do away with a key fob and use your phone to unlock, start ignition etc...
