Why are magnetic strip cards considered a poor choice for a secure facility?

Magnetic strip cards are often regarded as a poor choice for secure facilities primarily because they are easily duplicated. The technology behind magnetic strips is relatively simple, and it does not have robust security features. A basic magnetic strip contains data encoded in a format that can be easily read and copied with standard equipment. This makes it relatively straightforward for malicious individuals to duplicate the card using readily available tools, posing a significant security risk for facilities that require stricter access controls.

While the potential for duplication is a crucial factor, it is important to note that the other aspects, such as cost, the need for special readers, and storage capacity, do not contribute as significantly to the overall security weaknesses of magnetic strip cards. There are more advanced card technologies, like key fobs or smart cards, which incorporate encryption and other security measures to mitigate these vulnerabilities effectively.
