Touch ID is a feature that was first released with the iPhone 5S. It is one of the three security options included with Apple devices, the others being the Passcode Lock and Face ID.
Touch ID is activated through a fingerprint sensor built into a home button with a sapphire surface, and can be used for unlocking an iPhone, iPad or MacBook, as well as authorizing purchases.
