Assistant U.S. Attorney Mark R. Aveis says the card was taken from the wallet of James Fayed as authorities searched Fayed's Southern California home. The car was linked to Fayed because security cameras captured an image of a license plate and the car was traced to a rental agency near Fayed's business in Camarillo, Calif., the newspaper said.

Aveis made the disclosure Monday during a hearing in U.S. District Court in Los Angeles, where Fayed faces felony fraud charges involving an international gold trading company he operated with his wife, Pamela Fayed. She was killed in the parking garage of a Century City, Calif., office building after leaving her lawyer's office.

The couple ran two companies, Goldfinger Coin and Bullion Sales and a related online gold-trading company, E-Bullion. A judge had been scheduled to hear arguments on Pamela Fayed's request to have the business treated as a separate entity in the divorce because she feared her husband was trying to conceal assets.

James Fayed was arrested Friday at his home.
