chelsea asked:


I recently bought a magnetic card case to carry my credit cards and it seems that the magnet is destroying my credit cards. I had a case exactly like this (same brand, same type) before and the magnets never did this before. Is there anything I can do?

I already wrote the company that makes the card case and they were no help at all.

   I doubt the magnetic card case has a strong enough magnetic field to damage your cards. Typically, it would take a magnet of a several tesla to do any harm. Check the back of cards for scufs and scratches.

   Keep your cards away from any magnet.

   If you can enclose them in a metal case that might help; Magnetism can not penitrate a metal shell.

   Mythbusters did a show about this they tried all sorts of things and found it very difficult to damage the encoded info.

   You typically need an alternating magnetic field to damage magnetically encoded information. A magnet in a credit card holder isn’t likely to do it.
