How do hotel key cards get demagnetized?

Cards with scratches, exposure to debris, and other types of physical damage can be rendered unusable. Key cards may become inoperable when the magnetic stripe is demagnetized through exposure to magnets. Name tags, signs, and purse and wallet closures, and mobile phones are all potential sources of magnet exposure.
