"A Japanese engineer's box of tricks is helping detect
forged banknotes."
Counterfeit dollar bills are judged on a scale of one to
nine, with the crudest at level one. The detector
machines that existed before Matsumura's could only pick
out bills at around level five or six. Supernotes are
ranked between seven and nine and have been almost
impossible to detect. Matsumura says supernotes do have
flaws, though, and his machine can spot differences in
the printing by referring to a histogram, or statistical
graph, of patterns on real US notes. Each supernote
tends to have two or three minute aberrations.
Consequently, sensors check for any variations at 12
points on the note. A 0.9-second scan also monitors the
thickness of the paper and the printing ink.
The company can only produce 500 units a month, but
already has orders for 45,000.

Since the bulk of forged US$ (made in Syria and/or Iran?),
hundreds of millions, alledgedly are circulating in Russia,
will this bring down the Russian black market economy?
Or will they outlaw the Japanese box?
