can anyone help me find an article that shows mobile phone has no effect on magnetic stripe cards?

in fact, once I used my card … then I just got my purse and my mobile phone was also there (but not very close to it), then after 15 minutes I used my card again …….. and I found it `s not working …….. I just want to know whether the effect is moving, or perhaps there was a problem with the card on your own or what? Is possible to put two magnetic cards near each otrher, result dameging both?

You are not required to prove that an article. The speaker phone has a small magnet, like all speakers, large or small. So if you have together … literally: – open the phone to discover the speaker and then paste on the card … magnetic card then you will be a kind of useless! So, it can have some effect, but I really have to look problems like this happens.
