Can a phone demagnetize a credit card?

While it’s theoretically possible that a cell phone can demagnetize a credit card (or vice versa), it’s highly unlikely and borders the line between possible and impossible. The magnetic strips on credit cards are difficult to demagnetize because of how thin they are and how they’re manufactured.
