Have you ever noticed the circle-inside-two-bars symbol on your passport? This symbol signifies the presence of an RFID chip embedded in the cover. Since August 2007, all U.S. passports have come with this chip, which is intended to deter fraud and improve security. The chip contains the same information that is printed on the passport’s data page: holder’s name, date of birth, place of birth, and other biographical information. It also stores a digital photograph of the passport holder for facial recognition purposes.
