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 }
