A Texas high school student is being suspended for refusing to wear a student ID card implanted with a radio-frequency identification chip.

Northside Independent School District in San Antonio began issuing the RFID-chip-laden student-body cards when the semester began in the fall. The ID badge has a bar code associated with a student’s Social Security number, and the RFID chip monitors pupils’ movements on campus, from when they arrive until when they leave.

Radio-frequency identification devices are a daily part of the electronic age — found in passports, and library and payment cards. Eventually they’re expected to replace bar-code labels on consumer goods. Now schools across the nation are slowly adopting them as well.

The suspended student, sophomore Andrea Hernandez, was notified by the Northside Independent School District in San Antonio that she won’t be able to continue attending John Jay High School unless she wears the badge around her neck, which she has been refusing to do. The district said the girl, who objects on privacy and religious grounds, beginning Monday would have to attend another high school in the district that does not yet employ the RFID tags.
