iPhones with Touch ID look different than iPhones with Face ID, and it can also change how you use certain features on your device. Here’s how to spot a phone with Touch ID—and a list of models that support the feature.
Touch ID is a biometric authentication feature that recognizes your fingerprint to verify your identity. To use it, you gently place your finger on the Touch ID sensor build into the home button. It comes in handy because you don’t need to type in your PIN number or passwords as often when purchasing apps, logging into accounts, or unlocking your iPhone.
