I know someone who works at Best Buy and there manager said come June that Google Wallet(So Apple Pay would too?) would work there and that they are getting new pos system, which I figured was for EMV. Now I doubt they will actually support NFC since they are very for currentc, but you never know. "In the ensuing weeks, CEO Dekkers Davidson made the surprising statement that MCX is technology-agnostic and could work alongside Apple Pay in its partner stores." http://www.mobilepaymentstoday.com/articles/as-mobile-wallet-market-matures-mcx-sits-on-the-bench/
They may make it hard to use or make it so there's still some way to track you. Like entering a phone number or scanning a loyalty card before the NFC would activate.
