Question
Which of the following technologies are most likely used with badge cloning? (Choose two.)
- A. NFC Correct
- B. RFID Correct
- C. Bluetooth
- D. Modbus
- E. Zigbee
- F. CAN bus
Explanation
Access badges are contactless cards that use RFID (for example 125 kHz proximity cards) or NFC (13.56 MHz smart cards), and tools such as the Proxmark read and copy their identifiers onto blank cards. Bluetooth and Zigbee are wireless personal-area and IoT networking protocols, while Modbus and CAN bus are industrial and vehicle bus protocols; none of them is used by access badges.
