Triad industries include international heroin trafficking, production of forged credit cards, and trafficking in persons for commercial sex. During the Vietnam War, drug trafficking Triads expanded their operations. They then followed the market and internationalized the operations when Americans withdrew themselves from the war. Triads bring women in under the appearance of being tourists. Once the tourist visa expires, a different group of women arrive to replace them. Restaurant and entertainment workers, ones who may be in debt, are used by the group and used as skimmers. They have pocketed skimming device to steal credit card information.
