Newflash, no current security measure isn't vulnerable to a sophisticated, targeted attack by a skilled/knowledgeable individual or group.
My credit card info was just stolen last night.....I can tell you right now I am so ready for Apple Pay and will be actively trying to avoid places that don't accept it. At least until the chip/pin is viable here in the US. The few places where it works are apparently unbearably slow and inefficient.
Luckily for me, giving up shopping at Wal-Mart won't be too difficult....lol
That and using iWork apps on a larger more mobile screen are what pushed me over to the 6 Plus.
I doubt any spur of the moment criminal is going to go through all of that trouble to get into my phone and steal my GBs upon GBs of slow mo video of me kissing my wife.
I can't wait for Apple Pay myself. Even in Baltimore Maryland, the county and city, there are TONS of terminals just waiting for me to wave my phone and go.
