Jan has an iPhone 6 and she's worried that someone is hacking into her digital wallet and getting her credit card. Leo says it's probably not the case. More likely, she inadvertently activated Apple Pay, which she can do if she presses the home button twice. Pressing the home button again makes it go away. It's designed that way to make it easy to pay with Apple Pay quickly when the screen is locked.
Can she use more than one thumbprint on Touch ID? Leo says no. She can use fingers on both hands. But if it doesn't open, it may need to be retrained.
