> Touch ID (combined with a home button) is a lot faster. You can reach into your pocket or handbag, put the finger on the button and press it while you're taking it out. By the time your phone is out it's unlocked and on the home screen. I don't recall seeing people failing to unlock their phones while paying with Apple Pay before but now it's a reasonably common occurrence if they didn't "prime" it ahead of time.

I was excited when I discovered this, but I now consider this “feature” to be a security issue. I used to “prime” my Touch ID-equipped iPhones until I accidental authorized an in-app purchase because my thumb was pre-placed on the sensor.

Never again.

I had modified the Accessibility settings so that resting a finger on the sensor would unlock the device, and when reverting that setting I still ran into the same issue.
