Students 'suspend' their rights when they attend school, private or government schools. If there is a uniform dress code, they give up their 'right' to wear whatever they want. They give up their 'right' to free speech by having to be quiet during lectures. They give up their 'right' to freedom of movement by having to attend certain classes at certain times. They give up their 'right' to eat by only having food in the cafeteria. And on and on.
The student has the 'right' to attend the school, or find another if they don't like the rules.
This is not at all comparable to government tracking all citizens all the time. Nothing the RFID chip in the ID badge does anything an army of union hall monitors couldn't accomplish. I commend the school for trying to cut cost and improve attendance. They are simply using technology to enforce rules.
I’m glad you aren’t in charge.
