Abstract

A flash memory card structure with an external contact structure according to a published standard, such as the USB standard, also includes a second data transmission path, such as a wireless one. A removable cap fits over the card to cover the external contacts when they are not being used as a memory data path. One of two or more different caps may be selected to be placed on the card in order to control operation of the second data transmission path, such as to select the distance of wireless transmission from one of two or more pre-set distances. Power to operate the memory card through the second path, when not connected to a host, may also be provided through the external contacts by including a battery in the caps.
