Use the Internet and other sources to research the two disadvantages of standard biometrics: cost and error rates. Select one standard biometric technique (fingerprint, palm print, iris, facial features, etc.) and research the costs for having biometric readers for that technique located at two separate entrances into a building.

Finally, how often will this technique reject authorized users while accepting unauthorized users compared to other standard biometric techniques
