General Description
The ALPU-P is strong encryption chip even in
turbulent circumstance such as static electricity.
Valuable products made with strong encryption can
be prevented competitor from being copied with the
least expense or efforts and an amount of
production can be tracked with a unique serial
number in individual chip.
