I'm a senior in the same Science and Engineering program that Andrea is a member of. Some points:
1. Microwaving the cards causes visible burn marks.
2. The school has also blocked student led petitions against the ID cards, circulated during passing and free periods, on the grounds that they "disrupt the learning environment".
3. Thus far, the only students who have gotten in trouble for not wearing the ID cards are the vocal ones, like Andrea, or those who get in trouble for something else. However, the administration is starting to enforce the ID rules more heavily.
I sincerely hope Andrea succeeds, and that this doesn't set an alarming precedent for the removal of student rights. Please let me know if you have any questions about the IDs or the program.
