Unique ID
The devices feature a 96-bit unique device identifier which provides a reference number that
is unique for any device and in any context. The 96 bits of the identifier can never be altered
by the user.
The unique device identifier can be read in single bytes and may then be concatenated
using a custom algorithm.
The unique device identifier is ideally suited:
