What type of security feature is often included in a Smart Card?

Smart cards often include encryption for stored data as a fundamental security feature. The primary purpose of a smart card is to securely store sensitive information, such as personal identification or payment details. By applying encryption, the data becomes unreadable to unauthorized users, ensuring that even if the card is physically compromised, the information remains protected.

Encryption algorithms are used to manage and secure the data stored on the card, providing a robust layer of security. This is important for preventing data interception during transactions, which is critical in applications ranging from banking to access control.

Other techniques like voice recognition, fingerprint scanners, and face recognition capabilities are typically associated with biometric authentication, which may be used in conjunction with a smart card but are not standard features of smart cards themselves. The incorporation of these types of biometrics can enhance security but they are not intrinsic to the smart card architecture, making encryption the most relevant feature in directly securing the data contained within the card.
