its not a real NIR spectrometer, it can only "detect" things that have previously been loaded into its database of "scans". Looks like many people are getting awful results with it, so it may get better in time for commonly scanned items, but I don't really need it to tell me an apple is an apple.
What good is a pill detector that can only identify a pill that has already been detected previously? What if its a mixture of drugs, like in a powder? Or a substance they havent loaded into the database?
I think it is "a real NIR spectrometer", but otherwise you are correct about its limitations.
Still, if you create an app trained to know what pure/perfect MDMA or heroin looks like, it should be able to tell you if that's what you have, or if you...
