Find document about java card that is easier to read
I have read the ISO/IEC 7816 and ISO/IEC 14443 specifications for some time. However, I found it's a little hard for me to understand, and sometimes I was confused by the wording. Could someone here recommend any document that is easier to understand? Much appreciated.
