You typically pay with the student ID card or you employee badge, which is preloaded with money or linked to you monthly salary.\n\nThe security of some of these systems is severely broken due to the usage of old and insecure RFID/NFC technologies. We will learn some basics about those insecure RFID/NFC technologies and hear stories of broken systems I've analyzed in the past.","original_language":"eng","persons":["Gerhard \"ikarus\"
