I don’t know about that. When they first put magnetic strips in driver’s licenses, I heard that putting the license near a magnet would would make them where they could not be read. I took mine out and for a whole weekend placed a very strong magnet on top of them. It did not work. The best thing to do is resist.
It takes a VERY strong magnet. STand near an MRI machine in a hospital when it is running and you will wipe your credit cards.
