I still have a problem. When I send APDU command to my card, it always returns "61 02".
e.g.
>>80011122010102
<<61 02
Why ? I want to know the reason ? Am I making any mistake ?

61 02 means that there are 2 more bytes to the response. Send a GetResponse APDU to get those 2 bytes.

You can see information about this in the ISO7816-3/4 specification, read specifications first ...
