'The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.'

The RFID chip neither searches, seizes nor flags anyone as a threat. It is merely an indicator, just like those big 3-inch tall numbers on your plates. Your same argument would apply to having license plates on a car, the ONLY difference is that the RFID process is automated, and physically reading the numbers is manual.

I think you failed your civics class in school, if you ever took one.
