Re: Understanding Access Condition Bytes
Hello! Can someone explain by using some examples, the access condition bytes being used in Mifare's 1K cards?
Thanks!
Answering myself 
Using ACS Mifare Key Management Tool I was able to understand and analyze options bits in Mifare Cards really easy.
Hope that helps to someone else.
