Also Know, why do key cards demagnetize? Credit Cards/Cell Phones The theory behind this is that magnets causedemagnetization of magnetic stripes, and since magneticstripes are in fact magnetized, this magnetic energycan cause another magnetic stripe to demagnetize.Another common myth is that cell phones cause swipekeys to demagnetize.
can a cell phone demagnetize a key card?
The larger the magnetic field, the more likely it is toeffectively demagnetize the magnetic strip. So, doesyour phone produce a magnet field? The answer is yes, but itisn't strong enough demagnetize your creditcards.
Can RFID keys be demagnetized?
RFID interference is a common, but not the onlyway your access card can get demagnetized. When onemagnet comes close to another, it can affect the othercard's magnetic field. This can happen with a magstripecard, ending up in having the card demagnetized and the dataerased.
