Isn't there a chance the magnetic field that the phone produces will demagnetize your credit cards or any RFID access cards you may carry?

    I have a similar case that hold 3 cards and I've never had a problem with the magnetic strips. All have worked just fine. I've been using this case for 5 months now. Great case, very cool to have your cards with your phone. To see the case, just search amazon for Incipio Stowaway Credit Card Case for iPhone 4/4S

  • Not a problem. I've had this case for about a year now and have not had a problem with the 3-4 cards I carry in this wallet.

  • Apparently not. I've owned one of these cases with my 4S for quite a while now and have had no problems.
    I REALLY like the case and recommend it to everyone that comments on it.

  • My credit cards have been fine.

  • I have been using a similar kind of product for over a year now and have not had any problems with any of my (credit) cards.
