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).
