    Hello everyone

    am doing a research project for Uni, about security, and aim to log the data transfer and communication process between the Smartcard and the Reader on a door lock, i have done research into smartcards and found that all the data transfer and comunication is sent through the I/O pin of the smartcard, the smartcard uses Frequencey of 4.76 MHZ and operates at 5V and not forgeting the Clock signal pin and ground

    my question is

    can i log this data directly to my laptop using a MAX232 and Hyperterminal? while the card is communicating with the reader

    am i going about this, in the right way?

    any help would be appretiated

    thank you

    Also check ISO/IEC 14443 which ties into the suggestions of mrmeval.

    thank you for the prompt reply


    i have been reading through the Specification for the ISO 7816-4, most of the information is quite difficult to understand,

    i still not sure about how to go about approching this task, as it is my first time doing this

    any guidence or pointing in the right direction would be great?

    i know the communication between the reader and card is done serially using T=1 Protocol

    thank you

    Here is a link to a how-to on smart card communications - http://www.faqs.org/docs/Linux-HOWTO/Smart-Card-HOWTO.html.

    There are enough articles on smart card security issues and implementation on the net, such as in this link - http://www.tyndall.ie/dte/smartcard.htm - that it would seem quite possible to research the topic without making your own hardware.

    Frankly, this thread is about to be closed. Let us suggest that you establish some credibility here - what is your university, and who is your project advisor? What, precisely, do you intend to be able to demonstrate by making an apparatus that will enable you to monitor the communication between a smart card and its reader that is not already known? Will the university support your claim to be conducting a research project? Quite frankly, if I were doing similar research, the internet is the absolute last place I would go to in order to solicit assistance. The result could affect the entire university's data and physical security. I can hardly believe a legitimate researcher would ever solicit input from faceless entities who might be willing to exploit any revealed security flaws.

    Please establish some form of credibility or do not expect further assistance of any sort.
