Statement C, “It can never fail,” is not correct. Electronic systems, including card readers for access control, are subject to potential failures. These can include technical glitches, power outages, software errors, network issues, or physical damage to the reader or the card. While generally reliable, stating they can *never* fail is inaccurate.

– Card readers are electronic access control devices.
– Electronic systems are susceptible to various forms of failure (technical, power, software).
– Human guards have different failure modes (bribed, distracted, tired) compared to electronic systems.

Statements A, B, and D highlight advantages of automated access control: being incorruptible (A), potentially more economical in the long run (B), and consistently vigilant (D), compared to human guards. However, the possibility of technical failure remains a reality for electronic systems.
