A school district in Texas came under fire earlier this year when it announced that it would require students to wear microchip-embedded ID cards at all times. Now students who refuse to be monitored say they are feeling the repercussions.

Some pupils say they are already seeing the impact, though, and it’s not one they are very anxious to experience. Students who refuse to walk the schoolhouse halls with a location-sensitive sensor in their pocket or around their neck are being tormented by instructors and being barred from participating in certain school-wide functions, with some saying they are even being turned away from common areas like cafeterias and libraries.
