This report talks about security of NFC/RFID cards. It first describes the most widely-used type of cards, MIFARE Classic, and then considers a real-life application, namely Estonian public transportation cards. The communication between a real card reader installed in Tartu bus and a Tallinn public transportation card is eavesdropped and analysed on high level.

The report has been published for the UT course “Research Seminar in Cryptography (MTAT.07.022)”.
