Scammer reads p-chip patent, realises there's only a small range of laser diode wavelengths that can penetrate cheese. Buys chipped cheese, breaks the cheese. Chipped pieces found using laser excitation pulse and sensor with a notch filter. Save the wedge with the most chips to repeatedly break down to get chipped cheese crumbs, insert into bogus wedges, profit.

I'm sure the idea can be refined, but I'll leave the fine details to the dairy delinquent curd counterfeiters.
