i really don't know what the big deal is because there are only 7 places that utilize this feature (/sarcasm...there's only 2 places). i had a friend time our transaction, mine with my wallet and his with his nexus. we ordered and waited to say start and i dug into my wallet, pulled out my card, slid it in and entered my pin and was done quicker than it took him to pull his phone out, power it on, enter his pin to unlock it, get to the app, enter the pin and had took 2 tries to touch the paypass thing. all the while he almost drop his phone.
until there's more acceptance, it's something meh...i can live without. where i live i know mc'd accepts it and i'm not a fast food guy. sadly, i use the 4bucks app more because i use it to pay for my caffeine fix. i say sadly because it's not an exclusive feature i can rub my isheep friends with.
i undestand carriers, banks, cell manufacturers, ect are pushing hard against google but i don't know why google is caving in by not allowing this to work by hackers.
