This question is not answered

I was curious what the "SC" slot above the HD on my E6420 was for is it some kind of expansion port? I cannot find referance of it function anywhere on the web site.

  • Isn't that the smart card slot??

  • Hi Tomstill,

    Welcome to the Community. Bacillus is correct its the smard card slot, also called the express card slot. ( commonly wireless cards )

    Hope this helps.

    Thank you


  • Thanks for responding to and answering my question.
  • The SC slot and the ExpressCard slot are not the same.  I have a Latitude E6410, and it has both a smart card (SC) slot on the left side and an ExpressCard (EC) slot on the right.  The EC slot is about 3 times thicker.  The smart card slot is for reading smart cards (http://en.wikipedia.org/wiki/Smart_card), and are a way to verify someone's identity to allow them to use the computer, and are common with the government and various companies.  The Express Card (http://en.wikipedia.org/wiki/ExpressCard) slot is for expansion devices, like wireless cards or USB 3.0 ports.  ExpressCard is the newer and much faster replacement standard to old PCMCIA cards.
