4.1.2.3.3. Read Binary Blocks
The Read Binary Blocks command is used for retrieving multiple data blocks from the PICC. The data
block/trailer block must be authenticated first.
Read Binary APDU Format (5 Bytes)
Command Class INS P1 P2 Le
Read Binary
Blocks
FFh B0h 00h
Block
Number
Number of
Bytes to
Read
Where:
Block Number 1 Byte. The block to be accessed.
Number of Bytes to Read 1 Byte. Maximum 16 bytes.
Read Binary Block Response Format (N + 2 Bytes)
Response Data Out
Result 0 <= N <= 16 SW1 SW2
Read Binary Response Codes
Results SW1 SW2 Meaning
Success 90 00h The operation is completed successfully.
Error 63 00h The operation has failed.
Example 1 : Read 16 bytes from the binary block 04h (MIFARE 1K or 4K)
APDU = {FF B0 00 04 10}
Example 2 : Read 4 bytes from binary Page 04h (MIFARE Ultralight)
APDU = {FF B0 00 04 04}
Example 3 : Read 16 bytes from binary Page 04h (MIFARE Ultralight) (Pages 4, 5, 6 and 7 will be
read)
APDU = {FF B0 00 04 10}
