Hello friends,
I have a task to write some data on the chosen memory address location, using ACR38 SAM Smart Card Reader and SLE5542 card. To test reading and writing processes I have downloaded ACS Simple PC/SC Demo (Borland Delphi 7) from http://www.acs.com.hk/index.php?pid=tools.
(I have Win7).
My problem is that only APDU commands with CLA=FF is correct in the application. I would like to know how to choose CLA correctly? What influences on choosing of CLA?
I have to read the Programmable Security Code for my memory card SLE 5542, but without any success. How to do that correctly?
Thank you very much in advance.
Alenan
