Dawn and Mike Cantrall's daughter, a seventh-grader at Brittan Elementary School, poses at her Sutter, Calif., home, wearing the Radio Frequency Identification tag that the school asked her to wear on Tuesday, Feb. 8, 2005.
Next week, a federal judge in Texas will consider whether a San Antonio high school can require a student to wear a badge containing a SmartID locator microchip.
The schools says it helps them keep track of students and account for attendance, but 15-year-old Andrea Hernandez says the badge is a "mark of the beast," and wearing it violates her Christian beliefs.
However, according to school officials, if the program works as expected it could mean an additional $1.7 million in funding for the school district suffering from budget cuts.
For more on this case and why microchips could be headed to a school near you, we're joined by Declan Mccullagh, chief political correspondent & senior writer at CNET.
