Magnetic field bag?

[ratfink11]

Oes anyone know of a jacket/bag for an IPad that will prevent the escape of the magnetic field. I am always wiping my cards with magnetic strips because I put my iPad to close to them. Any help appreciated.

Magnetic fields drop off rapidly with distance. So the best bag is just one made of air -- distance! And it is free.
