Mifare read APDU command recived 63 00 - nfc

Question

All!
I'm trying to read data from mifare card 1k.
to get ID
I send: 0xFF 0xCA 0x00 0x00 0x00
Recive: 0x00 0x00 0x00 0x00 0x00 0x00 - ??? it's normal?
to load auth key to reader
I send: 0xFF 0x82 0x00 0x00 0x06 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF
Recive: 90 00 - it's ok
to authenticate in block 01
I send: 0xFF 0x86 0x00 0x00 0x05 0x01 0x00 0x01 0x60 0x00
Recive: 90 00 - it's ok
to read data from block 01
I send: 0xFF 0xB0 0x00 0x01 0x0F
Recive: 63 00 - how a understand it's authentication error
I can't understand - why?
My code:
#include "stdafx.h"

if ( SCARD_S_SUCCESS != lReturn ) {
printf("Failed SCardDisconnect\n");
} else {
printf("Success SCardDisconnect\n");
}
system("pause");
return 0;
}
Can anyone explain why i got 63 00?
Thanks.

Answer 1

Afair your read command has to be: "0xFF, 0xB0, 0x00, BLOCK, 0x10". You send buffer length 0F - which is decimal 15 - but you have to read 16 Byte, which is 0x10.
Hope this helps

Answer 2

In Mifare Classic 1K tags There are 16 Sectors and each Sectors contains 4 Blocks and each block contains 16 bytes.
Sector 0 contains Block (0,1,2,3)
Sector 1 contains Block (4,5,6,7)
Sector 2 contains Block (8,9,10,11)
Sector 3 contains Block (12,13,14,15)....
Before Reading or writing from a block You must have to Authenticate its corresponding Sector using Key A or Key B of that sector. When Authentication is complete then you can read or write.
using this command you can authenticate sector 0 using KEY A(60)
byte[] authenticationByte = new byte[10];
authenticationByte = new byte[] { (byte) 0xFF, (byte) 0x86, (byte) 0x00,
(byte) 0x00, (byte) 0x05, (byte) 0x00,(byte) 0x00, (byte) 0x04,
(byte) 0x60,(byte) 0x00 };
When Authentication is succes then you will get 90 00. That is Success message. Else response is 63 00 , that means authentication failed. When Authentication complete then you can read block (0,1,2,3) cause sector 0 contains 4 block and those are block (0,1,2,3).
Here your problem is you are authenticating Sector 1 but trying to read data from Sector 0's blocks.
