CEO, MasterCard

The India-born former Citigroup (C, Fortune 500) executive wants MasterCard to be a leader in the mobile payments revolution. Earlier this year MasterCard unveiled PayPass Wallet Services, a system that lets customers make payments on their phones and online without entering their card information. Banga's other big bet: prepaid cards in emerging markets such as Mexico, South Africa, and Brazil. All told, it's no surprise that MasterCard (MA, Fortune 500) now generates 60% of its revenues outside the U.S. Investors are impressed: Since Banga took the helm two years ago, MasterCard's stock has more than doubled, outperforming archrival Visa (V, Fortune 500). --Mina Kimes
