What is the main advantage of using contactless smart cards over traditional magnetic strip cards?

The primary advantage of using contactless smart cards over traditional magnetic strip cards lies in their security features, including greater security against duplication. Contactless smart cards typically employ advanced encryption and authentication protocols that make it significantly more challenging for unauthorized parties to duplicate the card's data. Unlike magnetic strip cards, which store data in a relatively unprotected manner, contactless smart cards often use secure elements that protect against cloning and fraud. This superior level of security is essential in preventing unauthorized access to sensitive areas and enhancing overall access control measures.

While other options, such as higher durability, faster reading times, or lower manufacturing costs, may also apply to smart card technology, the key distinguishing factor that makes contactless smart cards particularly advantageous is their enhanced security against duplication. This aspect directly impacts their effectiveness in providing secure electronic access control.
