The third tier
of "field
verification" shows an audible
reader. This reader has an audible tone plus the signal
of a green light (shown in picture) that signifies the authenticity
of your secure document.
This reader, as with the laser pen, is specially tuned to the
CodeSafe®
patch and will only react when it's near a CodeSafe® area.
Dependent upon the "loading" of
the CodeSafe®,
the reader is able to give solid verification through a substrate.
Our
security
envelope is a good example of an application that could use CodeSafe®
on the interior and be verified through the envelope without ever needing
to be opened. Likewise, any document with a printed CodeSafe® seal
could also be verified while still inside the sealed envelope.
