java - Read smart card files -


i trying read smart card files , after long search can send apdu command select mf (master file) need access ef (elementary file) , here command i'm sending :

responseapdu r = channel.transmit(new commandapdu(new byte[] { 0x00,(byte) 0xa4, 0x00, 0x00, 0x02, 0x3f, 0x00 }));

and here response :

6f 1c 82 01 38 83 02 3f 00 85 02 03 7f 86 0c 7f 7f 7f 7f 41 60 60 7f 7f 7f 60 00 8a 01 05 90 00

i know got positif response 90 00 , next should in order access ef.

you need pick file , select same command. if google iso7816-4 find few sites describing read binary , read record commands. depending on file type selected. there not standard iso command listing dfs andd efs, though. try eficcid (2fe2 iirc) start, present in cards.
