APDU Commands - How they work ?
843851Feb 3 2010 — edited Feb 4 2010Hi,
Iam all new to the JavaCard programming and wanted to understand some basics. The APDU Commands (CLA, INS, P1, P2, ...) are they reserved commands (as in reserved words). If so, how do I get a listing of the same.
Eg. I am looking into one of the programs which have the following few lines,
SetLength(DataToSend, 13);
DataToSend[0] := $88;
DataToSend[1] := $10;
DataToSend[2] := $11;
DataToSend[3] := $00;
DataToSend[4] := $08;
DataToSend[5] := $F9;
DataToSend[6] := $FD;
DataToSend[7] := $CE;
DataToSend[8] := $8B;
DataToSend[9] := $F6;
DataToSend[10] := $F4;
DataToSend[11] := $14;
DataToSend[12] := $E0;
FSCard.SendCustomAPDU(DataToSend, ReceiveBuffer);
I believe the above writes info. to the card.
If Yes, how do I retrive the same from Card?
If No, then what does the instruction stand for?
Appreciate your help ....
