optical reader on GN3 ?

[Iso10]

I was digging in my files and find a weird folder named "opticalreader" with a .dat file inside .. my question is if that is the optical reader app from the GS4 ? And if so how do I get it to work ?

And thanks in advance

I would think this may be for the screen keep on feature Samsung uses.
