Which statement about smart cards is true?

Which statement about smart cards is true?

• A. Smart cards contain special holograms that identify the cardholder
• B. Smart cards are immune from physical, side-channel, and environmental attacks
• C. Smart cards are designed to prevent fraudulent online card-not-present (CNP) transactions
• D. Smart cards are embedded with a microchip that is not easily replicated

Answer: (D)

The key idea here is that the security of smart cards comes from the embedded microchip that carries cryptographic data and performs secure operations. That chip is designed to be difficult to clone or replicate, which makes counterfeiting_card production much harder. That is why the statement describing a microchip embedded in the card that is not easily replicated is the true one. Holograms, while sometimes used as an extra visual feature, are not what fundamentally prevents fraud and can be forged. Smart cards also are not immune to attacks—physical tampering, side-channel analysis, and environmental factors can still pose risks, even if mitigated. And while the chip supports secure online transactions, it does not by itself guarantee the elimination of fraudulent card-not-present activity.
