RFID = radio frequency...what's this magnetic stuff?
RFID isn't evil, people are evil. There are many uses for it, it's just the purpose it's used for which can be evil. For your clothes example, you can have a washing machine that can read the RFID in the clothes and automatically wash it according to its instructions.
