read/write SLE4442 memory card with WinSCard API in c#

Question

A bit of background information:

Inorder to read/write to SLE4442 memory cards, my app is currently using an Omnikey Cardman 3021 USB card reader, a Sumbsembly Smartca

Answer 1

APDU for writing to card, in your example, should be:

FF D6 00 50 01 01

Answer 2

FF,D2,00,01,03,01,02,03 (new pin = 1,2,3) does not work (also after verifying existing PIN: 6D,00,FF,20,00,00 03,FF,FF,FF) - It returns error code 6D00.

For us (yet) not a huge problem, as we code our cards now with the Xiring XiMax terminal (programmable terminal with it's own SDK, the terminal can store data in flash memory). However, we need to find a solution soon. I am interested in your (future) findings. Do you have the Omnikey SDK? We can send you working examples in C++ that can change PSC (pin) and data on SLE4442/5542 cards.

This week (so not tomorrow, as previously stated, we have many things going on and are constantly ) we will test the (so far) working code with the Omnikey 1021). Hope to help you out.

We always have 50+ Omnikey 3121 readers on stock and we can offer you these (1+) for a far batter price. Let me know if you are interested. I am also interested what where you are located and what applications you are developing.

Answer 3

Our Omnikey (3121) terminal writes data on SLE4442/SLE4442 cards perfectly, try this APDU: FF D6 00 04 10 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E AA see also: http://acs.com.hk/drivers/eng/API_ACR122U.pdf, chapter 5.4
