What distinguishes smart cards from ordinary credit cards?

Smart cards are distinguished from ordinary credit cards primarily due to their embedded microchips, which enhance their security features and make them more difficult to replicate. The presence of these microchips allows smart cards to store and process data securely, offering advanced encryption and authentication measures that ordinary magnetic stripe cards lack. As a result, even if someone gains access to a smart card, duplicating its sophisticated security mechanisms is substantially more challenging.

While the other alternatives touch on various aspects of card features, they do not accurately encapsulate what sets smart cards apart from regular credit cards. For example, while holograms can be a security feature on various types of cards, they are not unique to smart cards. Additionally, smart cards are not immune to physical attacks; they can be subject to tampering or damage just like any other physical object. Lastly, smart cards are versatile and can be used for both online and offline transactions, contrary to the assertion that they are primarily for online use. This versatility further reinforces why smart cards are considered an advancement over standard credit cards.
