Is there a failsafe for Touch ID?
Is there a failsafe for Touch ID? What happens if, heaven forbid, you lose your hand or arm?

If Touch ID does not recognize your finger, you'll be asked to try again. After five failed attempts, you'll be given the option of entering your Apple ID password. In addition, you will be required to enter your Apple ID password after:
Restarting your iPhone 5s
Enrolling or deleting fingers

"deleting fingers" I love the Soprano-esque sound of that
