iPhone X will have an elongated Power/Lock button on its side. They’re calling it the Side button and you’ll use it for things like Siri, Wallet, Apple Pay and more.

Jeffrey Grossman, a New York-based developer and co-founder of confidential messaging app Confide, has encountered code strings in the leaked iOS 11 GM suggesting a double-click of the Side button will confirm a pending Apple Pay transaction (like on Apple Watch).

Sifting through the GM build, he’s been able to confirm that iPhone X’s sophisticated facial recognition system based on depth-sensing 3D sensors works with Apple Pay. That doesn’t mean you’ll need to hold up the phone in front of your face every time you use Apple Pay.

Because it’s twice as fast as Touch ID, works from oblique angles and can sense when you’re looking at the device, Face ID will “just work” with Apple Pay. All you’ll need to do to confirm that transaction is click the Side button twice quickly, Jeffrey wrote on Twitter today.

This should work for Apple Store purchases as well.

The developer speculated, based on his code discoveries, that Face ID might be coming to iPad and iPod touch as well but that may not necessarily be the case—at least for iPod touch—because those code strings are almost certainly in there for future-proofing.

To naysayers: Brazilian developer Guilherme Rambo‏ has also acknowledged on Twitter today that the software does support Face ID for Apple Pay.

Cue the “less convenient than Touch ID” comments in 3, 2, 1…

    less convenient 🙂

      You’re a monster

      I agree! I will stick with the iPhone 8 with a button and finger printer for Apple Pay. I just hold my phone up to the terminal locked and it does its think, so simple. This complicates that process. I will wait till they figure out how to put the touch sensor behind the display. Until then no iPhone X for me, sorry Apple, if you couldn’t get it to work you should have waited.

    In 6 months everyone will remember. Hell everyone still remembers the iPhone 4 in the bar fiasco. This GM leak will outlive the iPhone X, guaranteed.

    • TheAvatarNice

      Us Apple enthusiasts do remember that, but the average iPhone buyer doesn’t and probably hasn’t even heard of those GM leaks.

        The average buyer won’t even know that the new iPhone was announced. Every year I come across people (sometimes the same ones) that don’t know or care to remember that September is launch month. The only thing that matters for the general public is what makes it better and when can I actually buy it.

    Honestly, I thought the loss of Touch ID would suck but then I’m reminded that Touch ID fails when you have any moisture on your fingers and is actually at times stupid inconvenient.

    • Boaz van Veen

      very true, but i have my doubts if face ID will work in direct bright sunlight.

      • TheAvatarNice

        I think it will as the Face ID sensor doesn’t use visible light, so it should be completely independent of the brightness/darkness of your environment.

      • Boaz van Veen

        sunlight emits infrared light as well. especially in bright conditions i have a bad feeling its not going to work well, if at all.

      • mickey

        Highly doubt Apple axes something refined as Touch ID for an alternative that is inferior let alone significantly worse. If anything, history shows Apple plays it safer than its competitors when releasing new tech/features.

  • :D

    I wonder if there would be any issues with banks not allowing FaceID payments

  • Jay

    Ive come to the conclusion that with FaceID will already unlock the device but you need to touch/tap the side button to get to the home screen.

  • M_Hawke

    Well, based on this description, it IS more inconvenient. Face ID may be twice as fast as Touch ID, but “face” it (HAHA), Touch ID is still quick. Currently, I carry my phone in my left pocket. To make an Apple Pay transaction, as I pull my phone out, my left (registered) thumb is on the Home button, I touch the reader and it’s done, no confirmation required. If I’m reading this article correctly, this means that I now have to tap the button twice to confirm the purchase. Granted, it’s not that big of a deal, but technically, that does make it more inconvenient.

    Also, at some businesses, the reader is placed in such a way (wedged between counter top POS items, the register, etc.) that getting that extra hand or finger in there to double-click that button is going to be a bit of work.

I wouldn’t use Samsung either with the finger print sensor on the back of the phone dumb placement in my opinion.
