Latching mechanism for surface contact card

A latching mechanism for a card member, comprising:

• a body defining a receiving cavity configured for receiving the card member therein, the body including a connector disposed in the receiving cavity the connector being configured for electronically connecting with circuits of the card member when the card member is received in the receiving cavity;
• a rotating bar located adjacent the receiving cavity, the rotating bar being rotatable to drive the card member to move into or out the receiving cavity by friction produced between the rotating bar and the card member;
• and
• at least one rolling ball rotatably received in the body, adjacent to the entrance of the receiving cavity, the rolling ball being configured for reducing friction against the card member when the card member is moved.

A latch mechanism for a card member for a portable electronic device, the latch mechanism comprising:

• an electronic device body defining a receiving cavity therein, the receiving cavity being configured for receiving the card member therein, the receiving cavity having an cavity entrance;
• a rotating bar rotatably located adjacent the receiving cavity, the rotating bar being configured such that when the card member is disposed below the rotating bar and aligned with the cavity entrance, the rotating bar is capable of pressing the card member;
• and
• at least one rolling ball disposed between the entrance and the rotating bar for reducing friction resistance against motion of the card member.
