I see no problem here. The school system is using the RFID tags to track truancy. Schools in Texas get state funding based on student count. If a ton of kids skip, they get less funding. This allows them to track and curb those issues. What the article doesn't talk about is that the Hernendez family was suing the school on grounds that "the school district was a herald of the anti-christ". They believed the RFID tags were a sign of the apocolypse. It was only until the ACLU got involved that this turned legitimate.
