Mobile phones have very powerful magnets in their speakers and they don't usually cause problems like that, do they? Maybe they have very good mu-metal shields in the sepakers.
That is valid concern but, as far as I know, magnetic cards are mostly being replaced with smartcards or RFID, that might not be an issue in a couple of years. I've not used the magnetic stripes in my cards in a long time, the ICs are so cheap and functional that using smartcards or RFID instead of magnetic stripe is a no-brainer in most applications.
