RFID and Security: Viruses threaten RFID tags

摘要

RFID tags are being used in an increasing number of places. For instance, they are used in the payment systems of public transport services in several cities and as library cards. In this article, we examine some security and privacy issues related to RFID tags. An RFID tag is a combination of a special IC (chip) and a small antenna. When such a tag comes within range of a corresponding reader, the RFID chip is powered by the energy transmitted by the reader. The reader and the chip can use these radio waves to communicate with each other in both directions.
