Examples:
// Read 8 bytes from AM104 starting from address 0
INT16 RtnCode,i;
AC_APDU Apdu;
Apdu.CLA = 0x00; // Instruction Class
Apdu.INS = ACI_Read;
// Command
Apdu.P1
= 0x00;
// MSB of starting address
Apdu.P2
= 0x00;
// LSB of starting address
Apdu.Lc
= 0x00;
// No input data for this command
Apdu.Le
= 0x08;
// Read 8 bytes data
//Exchange APDU with the ACR10 reader
RtnCode = AC_ExchangeAPDU(hReader, &Apdu);
if (RtnCode >= 0)
{
// print the data
printf("Data : ");
for (i=0; i < (INT16) Apdu.Le; i++)
printf("
%02X",Apdu.DataOut[i]);
// print the status bytes
printf("Card Status(SW1 SW2)=%04X",Apdu.Status);
