DingleBerries Posted May 17, 2008 Share Posted May 17, 2008 Quick Note: This was a quick tear down of a Dell SK-3106, standard issue for the United States Military but it is just as easy for a civilian to purchase one. Original Large photos are in my Flickr Stream. Docs: hxxps://ascp.monmouth.army.mil/scp/downloads/ standardspolicy_files/Army_CAC_PKI_Program.pdf hxxp://www.smartcardbasics. com/cardtypes.html Now the part you guys want, pics :) This is your standard CAC(SMART) Card.

tim.vangehugten Posted May 17, 2008 Share Posted May 17, 2008 Is the I/O layout for the gold contacts almost for every card the same? Cause I've an electronic ID card for a couple of years and I wonder if I could mess with it :P Quote Link to comment Share on other sites More sharing options...

Cause I've an electronic ID card for a couple of years and I wonder if I could mess with it :P I believe so. You might run into problems with protection though, some cards lock you out (IIRC they actually self-distruct and blow a tiny fuse) if you try to tamper with them and fail. Some smart cards (SIM cards for example) use 6 pins, so I'd imagine you'd need a different reader. I believe the pinouts are the same on most cards that share the same number of pins.

DingleBerries Posted May 17, 2008 Author Share Posted May 17, 2008 i have a few cards that a local business uses to pay out money to customers. i am thinking about using an acetone solution and just letting it eat away at the plastic, however if any of the other electronics inside are shielded with a plastic coating then... it just wont work.. so when i take apart a card i will post pics on this thread as well. The all the chips are from the same manufacture and the documentation is pretty well written Applications: hxxp://support.gemalto. com/?id=199#310 Documentation: hxxp://support.gemalto. com/fileadmin/user_upload/user_guide/GemPC410/GemCore_v1.21_Reference_Manual.pdf Quote Link to comment Share on other sites More sharing options...
moonlit Posted May 17, 2008 Share Posted May 17, 2008 Yeah, it's a pretty big name. A lot of CAMs (Conditional Access Modules, the viewing card in your cable or satellite box) are GemPlus cards. Quote Link to comment Share on other sites More sharing options...
DingleBerries Posted May 18, 2008 Author Share Posted May 18, 2008 Today i tore down the keyboard and ripped out the...keys lol.. and started tinkering.. This is what i found in the first 5mins or so... There is a reed that, when compressed, activates the reader its self... so i soldered a old reset button i had that way i can tell it to switch on and off with out a card being in... Also the cards do not stay mounted very long, about 15 secs, so i am looking for a way to make it stay mounted, meaning the led goes off after a bit. PICS: Original reed that the card depresses when inserted: Back side:(r12 and r14 are the switches reads) New switch soldered on:(i was using a Cold/Heat so excuse the sloppiness) Switch: LED activated from the new switch: this is a little more complicated then i had first thought.. but still a fun take down Quote Link to comment Share on other sites More sharing options...
