Biometric authentication are systems that rely on the unique biological characteristics of individuals to verify their identity for secure access. For example, biometrics can secure a bank account or health app on your Apple iPhone.

There are (or have been) at least four biometric technologies employed for smartphones. In order of global popularity, they are:

1. Face
2. Fingerprint
3. Voice
4. Eye

Fingerprint sensors today are the most advanced solution. Eye sensors are among the toughest to implement. Key players in these biometric fields include companies such as FPC Sweden or Qualcomm US.
