3. Face recognition: This is a biometric technology that uses facial patterns to identify or verify an individual.

4. Retina scan: This technique involves scanning the unique patterns of blood vessels in the retina and is considered a biometric identification method.

Conclusion

The option that is not a form of biometrics is Smart card.

Final Answer

Smart card is not a form of biometrics.
