Which of the following types of credentials can be used in EAC systems?

The answer focuses on the diverse range of credentials utilized in Electronic Access Control (EAC) systems, which are essential for enhancing security and streamlining access. Proximity cards and smart cards are examples of physical credentials that operate using RFID technology, allowing users to gain access when the card is near a reader. Biometric identifiers, such as fingerprints or facial recognition, add a level of security by confirming identity based on unique biological traits. Mobile credentials enable users to unlock doors using their smartphones, offering convenience and flexibility.

These credentials are specifically designed for EAC systems where security and management capabilities are paramount. In contrast, manual keys and traditional locks, while still relevant in some contexts, do not integrate with the electronic controls that characterize modern EAC systems. Numeric codes, while a form of credential, are limited in terms of security and user management compared to the multifaceted options offered in EAC. Password-protected digital entries may have relevance in certain digital systems, but they do not represent the physical access that EAC systems are tailored to manage. Therefore, the comprehensive approach of B encompasses various advanced technologies that enhance both security and ease of use within EAC environments.
