  1. Hi All,

    I would like to develop a simple contact smartcard reader to ISO7816...
    with a little bit of security... using the Philips TDA8009 IC and a micro.

    What cards would you recommend and where would you get them from in small
    volume.

    What protocols/standards would you suggest with a little bit of security.

    Thanks in advance for your suggestions amd info.


    Regards
    JG
     
  2. a simple contact smartcard reader to ISO7816...
    Are you sure you need that IC ?

    Sorry text is in German, but circuit should be obvious.
    The official protocol for "smartcards" with processors
    nominally requires a UART. But as transfer is halfduplex
    its easy to do it via a software-UART. You probably will
    not use that type of card anyway.
    With simpler/cheaper cards like SLE44xx its bitbanging.
    That probably excludes repackaged I2C-EEPROMs.
    Do you want to store data or only have a "key" ?
    For reading unprotected, but writing protected by PIN:
    here in Germany mainly SLE4442 ( 256 byte ) and SLE4428
    ( 1k byte ) are readily available for small volume applications.
    Try google & ebay for sellers.

    MfG JRD
     
  3. You can buy these commercially from £10 or so, ready to go + free software.
    typical cards are FUN4, Titanium2 etc.
