How magnetized are CACs? Can they be safely kept in a wallet or purse?
There is nothing about the CAC that is magnetic, except the mag stripe, which is a normal commercially available technology that is no more magnetic than the stripe on a normal credit card (it is manufactured in the same way and has data loaded in the same way). The chip is a normal integrated circuit chip that requires the presence of a small electrical current that is provided by a contact reader to function; there is no residual current or charge when the card is removed from the reader.
