I also struggled with the unidirectionality of NFC, but then I discovered that
both users can tap to send at the same time, and both sides with send and
receive.  So really, its an interaction question: Android has set up NFC to
only send data with user confirmation, which is done by tapping the screen
once in the NFC "zoom" mode.
