How can I protect my credit cards from magnets?

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.
