The iPhone X got a lot of buzz last week for many reasons, but one feature that really grabbed people's attention was Face ID - the facial recognition software used for unlocking the phone. Many expressed privacy concerns, including the head of the Senate privacy committee, who questioned how Apple would keep users 'faceprints' safe. The idea of your phone knowing what you look like is a little creepy, but we might have to get used to it. A forecast by Acuity Market Intelligence suggests that by 2019 all smartphones will have some type of biometric technology.
As we can see in this chart from Statista, biometrics are predicted to be on 100% of wearables and tablets by 2020, proving that once again Apple is way ahead of the curve.
