How to use NFC-Only smartcard with GnuPG?

I'm trying to use an Android smartcard emulator (to see if a smartcard can fit into my workflow) with GnuPG on Debian Sid. I have libNFC configured with a pn532 breakout that can see the applet on the phone. I have spent a literal hour googling this and turned up no relevant results other than "Android supports NFC OpenPGP smartcards!" and "Yubikey NEO supports NFC!"
