Hi Anmol,
You wrote: “… other card reading software is still showing me 3des in cipher algo.”. How can a software show you the used cipher? To show that you use a certain cipher, the software must authenticate successful with a known key.
If the old key is a 2K3DES key and you want to change it to an AES key, then it is still a 2K3DES key if the key change fails. You should get an error message after the change key command.
