Disable A Passport RFID Chip

How-To Overview

This wiki briefly describes RFID, its uses, its potential dangers, and why and how to disable its implementation in a US passport.

What is RFID

Radio Frequency Identification (RFID) allows for expedited identification of the object or person the tag is attached to. Using radio waves, remotely stored data can be accessed to help identify the object or person associated with or connected to the tag. The tag itself is a small, grid-like box--commonly affixed by adhesive--that is either "passive" (contains no internal power supply) or "Active" (contain an internal power source used to generate an outgoing IC signal).

RFID Uses

RFID tags are often attached to consumer goods by large retailers in order to discourage shoplifting. They can also be found in library books, warehouse stock tracking of all kinds, and testing with keys used to access automobiles. There has recently been RFID chip use and testing for fare payment in transit systems in Asia, Europe, and New York City. RFID chips have also been variously used in electronic toll booths, ski lifts in France, video game data storage, induction heating devices, and many other applications.

RFID tags are increasingly used in international passports. After January 1, 2007, all passports issued by the US State Department will feature RFID chips, which will store similar information to what is printed on the passport. The passports will purportedly feature a metal lining that will make access to the information nearly impossible when the passport is closed.

Disabling RFID Chips in Passports

In the interest of civil liberties threats raised by personal information made available via radio signal, the issue of destroying the RFID chip in US passports has been raised. It has been found that that striking the chip with a solid, blunt object will disable it without otherwise visibly damaging the passport.
