Former counterfeiter Arthur Williams Jr. mastered the 1996 $100 bill and printed nearly $10M in fake currency before serving 12 years in prison. Now an artist and speaker, he reveals how he discovered the yellow pages as the perfect paper, evaded Secret Service for years, and ended up imprisoned alongside his own son—plus his warnings about programmable digital currency. Williams combined 1985 offset printing technology with 1990s Photoshop to create counterfeit $100 bills so advanced they triggered the 2013 redesign with visual physics security features.
