Tuesday's indictment accused them of obtaining blank credit cards from China that bore the logos of giant financial institutions and activating the counterfeit cards using existing credit card numbers.
Earlier this month, federal agents recovered more than 80,000 phony cards and several credit card skimmers at a storage unit in the San Gabriel Valley. Earlier, investigators intercepted packages from China containing 12,000 counterfeit cards.
Jose Rolando Renderos, his 18-year-old son Jose Ulloa and Milagro del Carmen Alvarez Hernandez faced arraignment on Feb. 25.
Authorities say Alvarez used a fake card in December at a children's boutique in Los Angeles, spending more than $1,600.
