Strangely enough the 7-11 stores in my area used to be ahead of the curve and all accepted NFC payments until a couple weeks ago. I used Google Wallet and ISIS there a number of times. I noticed they had all replaced the terminals with iSC350 models that were no longer NFC enabled two weeks ago, though. The new ones support chip+PIN, though.
7-11 is part of the MCX consortium along with CVS, Rite Aid, Best Buy, Walmart, et al. They likely shut them off before Apple Pay went live so that they wouldn't find themselves in the same sort of stew as CVS is right now.
