How RFID Readers Power and Communicate with Cards: A Breakdown

Описание: In this informative YouTube Short, Viktor Petersson and Iceman dive into the mechanics of how RFID readers work and interact with RFID cards. Iceman explains how a reader, like a Proxmock, generates an electromagnetic field using its antenna. When you present an RFID-based card, its internal antenna picks up the field, which energizes the card and allows it to communicate with the reader. The card and reader are tuned to the same frequency, creating a resonance that excites electrons, powering the card.

Iceman further explains how tools like SDRs (Software Defined Radios) can be used to sniff the communication between the card and the reader. While the SDR cannot power the card itself, it can capture the traffic being exchanged. This fascinating discussion offers a clear understanding of the physics behind RFID technology and the vulnerabilities that can be exploited.

For anyone interested in RFID, SDR, or how wireless communication systems work, this short provides a simple yet technical explanation of how RFID readers power and communicate with cards. Stay tuned for more insights into cutting-edge technology and security!
