Extreme Credit Cards for the Biggest Spenders in the World

Wealthy patrons with shopping addictions are a tempting customer base for creditors, and so more and more of them are coming up with ways to make their services attractive to the biggest spenders in the world. The Centurion card from American Express is the leading status symbol to date, with its classy black card made of titanium that comes with exclusive perks like a personal concierge (to help you plan your spending) and special treatment at all the top retailers.

But the Centurion, better known simply as the "Black Card," is getting some competition for the top of the prestigious credit card pyramid. Companies like Bank of America and Citigroup are coming up with their own versions, and it seems the greatest competition so far is from the Visa Stratus Rewards card, aka the "White Card." And in the U.K. there's always the Ozwald Boateng-designed Coutts & Co.'s World card from the same private bank Queen Elizabeth uses.
