There are many approaches about giving information for people with visual impairment by using two-dimensional code.
But the installation of code has faults that losses design of the setting place.
The purpose of this research is to realize the information presentation system
for support of people with visual impairment by using QR code.
Then, We made invisible QR code with IR reflective and absorption ink.
In experiment, we confirmed camera cannot read invisible QR code,
but IR camera can do it.
