6.3. Read Binary Blocks
The “Read Binary Blocks command” is used for retrieving “data blocks” from the PICC. The data block/trailer block must
be authenticated first.
Command Class INS P1 P2 Le
Read Binary Blocks
FF B0 00 Block Number Number of Bytes to Read
Table 16: Read Binary APDU Format (5 Bytes)
where:
Block Number (1 Byte): The block to be accessed
Number of Bytes to Read (1 Byte): Maximum 16 bytes
Response Data Out
Result 0 <= N <= 16 SW1 SW2
Table 17: Read Binary Block Response Format (N + 2 Bytes)
Results SW1 SW2 Meaning
Success 90 00 The operation completed successfully.
Error 63 00 The operation failed.
Table 18: Read Binary Block Response Codes
Example:
1. Read 16 bytes from the binary block
0x04
(Mifare 1K or 4K)
APDU = {
FF B0 00 04 10
}
2.
Read 4 bytes from the binary Page
0x04
(Mifare Ultralight)
APDU = {
FF B0 00 04 04
}
3.
Read 16 bytes starting from the binary Page
0x04
(Mifare Ultralight) (Pages 4, 5, 6 and 7 will be read)
APDU = {
FF B0 00 04 10
}
