Chris wants to implement a biometric system for the entrance of his company. Which of the following systems is likely to be most accepted by members of his organization's staff?

Fingerprint reader systems are the most generally accepted biometric systems in common use for the entrance and other purposes today. Facial recognition systems are, in fact, increasingly in use and are also likely to be more accepted by user populations based on their wide deployment in phones, but they are not listed as an option. Both retina and iris scans are less likely to be accepted, whereas voice systems are both relatively uncommon and more disruptive for common usage.
