Unseen Waves: The Mechanics and Vulnerabilities of Modern RFID Systems A look into the wireless technology powering our world and the critical security gaps that remain hidden in plain sight.

Abstract

Every one of us would have been wondered when using a card at some ATM or at some metro station and that is just a simple tap and a beep sounds and our operation is performed or even some people would have experienced some locking and unlocking mechanism at some labs and private places where the users just have simple key ring or some card to scan and the door lock is open. It feels like magic for a new person who sees it the very first time or to the person who is unaware of the technology behind it. The magic is the RFID which is fully denoted as radio frequency Identification which consists of electromagnetic waves that just travel between two mediums between the scanner and the RFID Chip and data is transferred between them. So, every RFID card or tag has some unique ID which is used to recognize that specific one at the time of scanning.
