8.4.3 Reading the serial number
The read/write Electronic-Key contains a unique 8-byte serial number. This number is written by laser during the
Electronic-Key production process and can never be changed or deleted. The serial number is used for secure
distinction of every single Electronic-Key. It is necessary that all 8 bytes are completely evaluated for this secure
distinction. The serial number is appended to the freely programmable user data.
The serial number can be read by entering the start address byte number 116 and the number of bytes 8 (see
section 8.4.2).
