An enterprise is upgrading its security infrastructure to enhance identity verification at multiple access points throughout a busy office building. Management wants an authentication method that is entirely contact-free, works quickly so that staff are not delayed, and reduces the risk of unauthorized entry caused by shared or stolen credentials. Which biometric solution best meets these requirements?
A facial recognition system is the best fit for a high-traffic environment because it is completely contactless and can authenticate users in less than a second. Modern face-matching algorithms have very low false-accept rates (≈0.08 % for the best NIST-tested algorithms) - enough to satisfy most enterprise security policies while eliminating queues.
Retinal scanners are extremely accurate but require each person to align an eye very close to a scanner, slowing throughput and making the process feel invasive. Proximity cards and PIN pads are fast but can be shared or stolen, so they do not solve the credential-sharing problem.
