Thank you mifare sdk.
I will try to implement the steps tomorrow.
1) My question on this topic is that how secure will be my card after I change the keys with the new keys that showed in your example?
2) At the moment I am using only one application in mifare classic. So is it possible to change all other sector trailer blocks key?
3) What should I have to do to protect my card from cloning?
4) Does mifare classic has any encryption or do I have to apply it by myself?
5) I am using Ubuntu 12.04 and the Qt IDE for development. My Pos Terminal has embedded Linux. So what kind of the secure encryption can I use?
Kind Regards,
