Reciprocal Distrust

Reciprocal Distrust by John Sasaki is comprised of two counterfeit detectors placed back to back.

As is customary, cashiers will be able to scrutinize a customer's bills using the "seller's" detector. However, as distrust must be reciprocated, customers will be invited to verify the authenticity of the change they are given back, using the "buyer's" detector.
