What type of RFID tag is embedded in current U.S. passports, and how can people protect themselves from unauthorized detection?

—Name withheld


Current passports used in the United States utilize high-frequency (HF) RFID tags based on the ISO 14443 standard. The passports now have a foil lining in their cover, to protect the tag from being read without a passport holder realizing it. For further protection, you could wrap the passport in tin foil, or carry it in a Mylar bag.
