Magnets causing issues with credit cards

The magnets are not nearly strong enough to wipe a credit card.

And yes, I have folded the cover around my CC, swiped it across the hinge and it still works.

I worry a little that it will damage my portable HDD I carry in the same bag, but from what I know magnetic field has to be very strong or very close to media to do some damage...
 
Mythbusters did a show on this and it took quite a bit to wipe a credit card, much more than these Neodymium Magnets can put out.

Unless you're referring to another kind of magnet, neodymium (NdFeB) magnets are amongst the strongest kind of magnets in existence - strong enough that you can incur serious injury if parts of skin or flesh are caught between two magnets. I would never let any magnetic-sensitive device or item near an NdFeB.

Yep. +1 on this.

The only time I've ever had an issue with magnets wiping cards was when I forgot to remove my wallet from my back pocket before entering an MRI (Magnetic Resonance Imaging) imaging room to off-load a patient onto the imaging unit table. Normal procedure is to remove all metal items, like hip tool pouches, stethoscopes, badges, pens, glasses, jewelry, and-of course-wallets. During the process of scooting this person into position on the table, my rear came close to the MRI unit several times. Not a single card in my wallet left the building unscathed, as I found out later on when I attempted to use them. Now THAT'S a magnet!

I have seen credit cards and magnetic parking tickets get wiped by the anti-theft demagnetizer at checkout counters, but I have no idea how strong the field strength is. (I would have guessed on the low side.)

How often do you put your iPad on top of credit cards?

I keep mine in my purse, but have been trying to keep my wallet and iPad at opposite sides.

If your purse is like most women's purses than credit cards and magnets, it seems, would be the least of your worries. LOL
I'd NEVER put my iPad in my purse, with all of those items :0
 
i've had credit cards, train cards, bus cards etc etc all wiped clean of magnetic info on numerous occasions in the past just by constantly carrying them together in the same pocket with my mobile phone. so yes, in my experience, the magnetic charge is enough to wipe some sensitive cards.
 
As mentioned before, the magnets in the SmartCover are too weak to cause any damage to CC's.

I have already tried it with my Visa card by moving it directly across the magnets and then afterwards testing it's functionality with a card reader.

Wow, it's strange that you all have had magnetic strip issues, I have never lost a magnetic strip, guess I have been lucky. I have many Neo Mags, some fairly large and have had them in the same bag as my wallet. When one of my credit or debit cards expire I will test this.

If your card expires how will u know if it works or not?
 
This discussion is leading nowhere without actual tests. So here is a short clip of running a Visa card over the magnets and afterwards testing the cards functionality with the help of a card reader.

Just a side-note: Don't expect any sound, I haven't yet figured iMovie out.
