U.S Centurion site say,
Double Membership Rewards points
You can earn double with Centurion partners, including Continental Airlines, Hyatt Hotels and Resorts, Neiman Marcus, Saks Fifth Avenue, and more, when you use your Centurion Card for purchases. You can also earn double Membership Rewards points--two points for every dollar you charge to your Centurion card--at stand-alone supermarkets, gas stations, drugstores, the U.S. Postal Service, or even when you pay your wireless phone bill.
