8.4.3 Reading the serial number

The Electronic-Key read/write 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 reliable

identification of each individual Electronic-Key. It is necessary that all 8 bytes are completely evaluated for

reliable differentiation. The serial number is appended to the freely programmable user data.

The serial number can be read using the command TL (see section 8.4.2 Read process) using the start address

byte no. 116 and 8 as the number of bytes.
