Abstract
A cellular telephone is provided with a wearable housing, desirably in a form which can be concealed in the user's clothing, wallet, or other place. The housing may be devoid of switches or buttons for controlling the cellular telephone, and control inputs can be provided through free space communications such as a short-range radio link. A module for use in portable communications devices includes chips superposed on one another on a stack, and incorporates an interposer for facilitating connections between the chips.
