The only high volume use of NFC in a PC would be for Secure Payments and Authentication where you use a mobile phone as payment credential holder or authenticator. Intel rejected this idea. QR has (forever) taken NFC's place. The QR phenomena is also getting strong in PoS terminal (shop) world since the NFC forum haven't realized that 7816 is an obsolete technology. 800 million Chinese have much better stuff than the West crippled by dated card level protocols.
