If it's better, patent and sell to vending companies? Yeah... patents are evil; but maybe a novel application of an existing technology isn't so evil in this case--provided it really is novel and not just a poor-man's vending machine detector, in which case the vending machine companies may already have a patent on it...

Somehow I doubt a 16x16 pixel grayscale sensor is going to detect counterfeit coins any better than the human eye, but maybe I should read TFA before I jump to judgement...
And maybe before posting, too? Just a suggestion.
Generally, if you're about to post something that is along the lines of, "this couldn't possibly work because ..." without (a) having read the article, and (b) being an expert in the field, best to think twice.
