Which credential type is typically used for touchless access in EAC systems?

• A. Biometric identifiers
• B. Proximity cards
• C. Traditional keys
• D. Coded entry systems

Answer: (B)

Proximity cards are commonly utilized for touchless access in Electronic Access Control (EAC) systems. These cards work by using radio frequency identification (RFID) technology, allowing users to gain entry simply by holding the card near a reader, which detects the ID from the card without requiring physical contact. This touchless capability enhances convenience for users and improves hygiene, making it especially relevant in environments where minimizing contact is crucial.

In terms of the other credential types, biometric identifiers require physical contact to scan fingerprints or facial features, making them less suited for touchless access. Traditional keys necessitate insertion and turning, which clearly involves direct physical manipulation. Coded entry systems typically rely on entering a code via a keypad, requiring physical interaction as well. Therefore, proximity cards stand out as the optimal choice for achieving touchless access in EAC systems.
