Problem with Pegoda reader and Mifare Desfire V1 card

Hello,

I'm writing test program for Mifare Desfire V1 card and find the following problem. When I send "Select Application" command to the card via Omnikey 5321 v2 CL SAM reader I have got the following log:

Mon May 23 09:42:30 2016

REQUEST:

Command = 0x5A 0x00 0x00 0x00

Request Lenght = 4

Request protocol = CL

>> 5A 00 00 00

RESPONSE:

<<Response Lenght = 1

Response status = 0x00000000 - SCARD_S_SUCCESS

<< 00

-------------------------------------------------------------------------

This is a normal answer, all is Ok.

When I send the same command to the RD710 reader I have got the following:

Mon May 23 10:00:12 2016

REQUEST:

Command = 0x5A 0x00 0x00 0x00

Request Lenght = 4

Request protocol = CL

>> 5A 00 00 00

RESPONSE:

<<Response Lenght = 6

Response status = 0x00000000 - SCARD_S_SUCCESS

<< 5A 80 25 01 00 00

-------------------------------------------------------------------------

Can anybody explain me for what reason I receive such an answer from the card?
