Apple Pay is ready for use at over 220,000 outlets across the United States. By using your iPhone 6 or 6 Plus, all you have to do is point your device at any NFC-enabled point-of-sale system compatible with Apple Pay, press your fingerprint on the home button, and voilà—you've just paid for something with your card.
As a matter of fact, the store doesn't even need to have Apple Pay compatibility to work with your phone. If their machines have NFC-technology, they'll recognize your device (unless they intentionally disabled it). Hell, even vending machines accept Apple Pay.
But today, while playing around with our Samsung Galaxy Note 4, we found out something else—the iPhone 6 and 6 Plus will try to connect with anything that has NFC enabled, including Android devices (though, not other iPhone 6s).
Since Apple didn't include any on-screen settings for NFC on iPhone 6 models, there's no way to turn it off. That means that any time it's close to an NFC-capable device, it's going to attempt and use Apple Pay. It's kind of annoying, but there doesn't seem to be any sort of security issue just yet. When I used my fingerprint to attempt payment, nothing happened.
Hopefully, Apple tries to fix this, either by allowing us to disable NFC or by making it so that Apple Pay only works with certain devices, like point-of-sale systems, rather than just anything that's NFC equipped.
