Which access control method would be MOST suitable to meet the requirements for logging employee entry and implementing two-factor authentication in a new security setup?

1. Proximity readers

2. Biometric readers

3. Smart cards

4. Keyless entry systems

The correct answer is: Biometric readers

The use of biometric readers is particularly well-suited for logging employee entry and implementing two-factor authentication due to their ability to uniquely identify individuals based on physiological traits such as fingerprints, facial recognition, or iris scans. This technology provides a high level of security because biometric characteristics are far more difficult to replicate or share compared to traditional access credentials, such as keys or passwords, which enhances the overall security posture of a facility. In a two-factor authentication setup, biometric readers can be combined with another form of verification, such as a smart card or a PIN. This dual-layer system ensures that access is granted only to those who possess both the physical credential and the unique personal identifier, significantly reducing the risk of unauthorized access. While other access control methods like smart cards and keyless entry systems can also support logging and might incorporate two-factor authentication, they may not offer the same level of uniqueness and difficulty in duplication as biometric identifiers. Proximity readers, for instance, often rely on RFID technology which can be more susceptible to cloning. Thus, biometric readers are an ideal choice for a robust security setup that prioritizes verification and logging of entry.
