• Maximum 16 bytes for Mifare Ultralight.
• Maximum 48 bytes for Mifare 1K. (Multiple Blocks Mode; 3 consecutive blocks)
• Maximum 240 bytes for Mifare 4K. (Multiple Blocks Mode; 15 consecutive blocks)
Example 1: 0x10h (16 bytes). The starting block only. (Single Block Mode)
Example 2: 0x40h (64 bytes). From the starting block to starting block+3. (Multiple Blocks Mode)
Note: For safety reason, the Multiple Block Mode is used for accessing Data Blocks only. The
Trailer Block is not supposed to be accessed in Multiple Blocks Mode. Please use Single Block
Mode to access the Trailer Block.

Success 90 00h The operation is completed successfully.
Error 63 00h The operation is failed.
Examples:
// Read 16 bytes from the binary block
0x04h (Mifare 1K or 4K)
APDU = {FF B0 00 04 10h}
// Read 240 bytes starting from the binary block
0x80h (Mifare 4K)
// Block 0x80h to Block 0x8Eh (15 blocks)
APDU = {FF B0 00

5.3.2.2.4. Update Binary Blocks
This command is used for writing a multiple of “data blocks” into the PICC. The data block/trailer block
must be authenticated first before executing the Update Binary Blocks command.
