Contactless Smartcard Security: Dominic Celiano

Contactless smartcards are common, from our University ID cards to our bank cards. Many of these cards are specified to operate at 13.56MHz.

What happens, though, if we use a different frequency, such as 16.00MHz? To answer this question, Dominic explains the basic details of how contactless smartcards work, and present an example reader.

Dominic then shows results from using both 13.56MHz and 16.00MHz with this reader. By taking this journey, we will uncover key lessons about the relationship between contactless smartcards and security, and show how using a higher frequency can allow for relay attacks.
