Face ID

Face ID is a facial recognition technology used by devices like smartphones and tablets to securely unlock the device and authorize transactions. It works by using a sophisticated system of cameras and sensors that map your face in three dimensions. When you look at your device, it compares the scanned image to the stored facial data to confirm your identity. This method enhances security, as it is designed to only unlock for the registered user. Additionally, it can adapt to changes in appearance, such as facial hair or glasses, to ensure continued accuracy.
