Card Reader & Biometric Access Flashcards

What does the term 'credential management' refer to in access control?

Answer: The lifecycle process of issuing, tracking, modifying, and revoking access credentials

Credential management encompasses the entire lifecycle of access credentials — from issuance and assignment to modification and revocation.

An iris recognition system is classified as which type of biometric modality?

Answer: Physiological biometric

Iris recognition is a physiological biometric because it measures a stable, physical characteristic of the human body.

Which access control model assigns permissions based on a user's role within an organization rather than individual identity?

Answer: Role-Based Access Control (RBAC)

RBAC grants access permissions based on defined organizational roles (e.g., 'employee,' 'manager,' 'security'), simplifying large-scale access management.

A reader wiring run exceeds the maximum recommended distance for Wiegand. The best solution is to:

Answer: Install a Wiegand signal booster or use OSDP over RS-485 instead

Wiegand is reliable only up to approximately 500 feet; for longer runs, a signal booster or switching to RS-485-based OSDP resolves the distance limitation.

In access control, 'two-man rule' (also called dual-custody) requires:

Answer: Two authorized individuals to both present credentials before access is granted

The two-man rule mandates that two separate authorized individuals must authenticate simultaneously before a highly sensitive area is unlocked.

Which technology uses a 13.56 MHz frequency and supports onboard data encryption for contactless smart card access?

Answer: MIFARE / iCLASS

MIFARE and iCLASS operate at 13.56 MHz and use cryptographic keys stored on the card chip, providing encrypted, more secure contactless transactions.

When a biometric access system is used at a border crossing or high-security facility, which performance metric is typically prioritized over the other?

Answer: Low False Acceptance Rate (FAR) to prevent unauthorized entry

In high-security environments, minimizing unauthorized access (low FAR) takes precedence over user convenience, even if legitimate users are occasionally rejected.
