A lot of people don't have land lines by choice, because they would rather have a cell phone? Okay. A cell phone is not required.
I answered your question. Why implement a system, if it doesn't actually improve anything. If this is only about truancy, instant record keeping doesn't matter. RFID is bad because it will cost money to replace a system that worked perfectly fine. Teachers calling attendance isn't why truancy happens. It doesn't enable truancy, or help it in any way. If you think truancy is a problem, then look at the real issues: Those that do it(Students), those that don't care(Parents), or those that don't reinforce rules against it(the school board).
This would just be an undue burden on students. I don't remember that whole article, but I'm not sure would would pay for those badges, who would pay for replacements etc etc etc. If student A has never been truant, why should they have to carry a special ID around? If student B is truant twice a week every week, why isn't he punished?

Thats what I think as well. I just don't see this as actually fixing any problems. The only one being something brought up a long time ago: If there is a school emergency, this system MIGHT help with locating them.
