UPDATE BINARY instruction
The UPDATE BINARY instruction writes data into a memory card (wired-logic PICC or VICC). Refer
to chapter 4 for details.
For any PICC/VICC but Mifare Classic, this instruction is executed without any prerequisite.
For Mifare Classic, to be able to read the sector's data, the application must be authenticated on
For Mifare Classic, to be able to read the sector's data, the application must be authenticated on
the card's sector. Your application must always invoke GENERAL AUTHENTICATE instruction (with
a valid key A or key B for the sector) before invoking the UPDATE BINARY instruction. Using the

Both the allowed range for the address and the value for Lc depend on the capabilities of the PICC.
