What does a “proximity card” do in an EAC system?

• A. It requires physical contact with the card reader
• B. It allows users to gain access when held close to a card reader
• C. It can only be used outdoors
• D. It cannot be used with biometric systems

Answer: (B)

In an Electronic Access Control (EAC) system, a proximity card functions by enabling users to gain access without the need for physical contact with the card reader. When the card is held near the reader, typically within a few inches, it transmits a radio frequency signal that is detected by the reader, allowing it to authenticate the user's identity and grant access to secured areas. This contactless feature enhances convenience and speed of access, making it an effective choice for many EAC systems. The design of proximity cards makes them particularly useful in high-traffic areas where quick access is needed, as users can simply wave or hold their card near the reader instead of needing to insert or swipe it. This functionality is a key differentiator from other types of cards that require direct physical interaction for reading.
