Abstract
Abstract The present patent application discusses a low profile information card chamber (107) used in a radiotelephone (101). The information card chamber accepts, retains and makes electrical contact to an information card (105). The information card chamber (107) makes electrical contact to the information card when the information card is properly inserted (105). The electrical contacts are located on the lower platform (213) of the information card chamber (107). Upon inserting the information card (105) into the information card chamber (107), the information card (105) is translated away from the electrical contacts (205). Prior to being fully inserted, the information card (105) is translated towards the electrical contacts (205). The two translational devices allow an information card (105) to be inserted into the information card chamber (107) without excessive wiping of the electrical contacts (205) by the information card (105).
