9. Laura Chambers, general manager of mobile, PayPal - 2011 Most Influential Women in Wireless

9. Laura Chambers, general manager of mobile, PayPal - 2011 Most Influential Women in WirelessAs head of mobile at one of the biggest and best-known online payment firms, Laura Chambers is set to preside over a market that many believe is primed to explode.

And it's clear that Chambers has no intention of letting the action pass her by: Just a few days ago, PayPal announced an NFC-enabled widget for Android, available later this summer that will let two users "bump" their phones together to transfer funds.

Indeed, as head of mobile at PayPal, Chambers is already in the middle of the fight: PayPal expects to transact more than $3 billion in mobile payments this year, and more than 8 million customers are making purchases on their mobile phones through PayPal, driving up to $10 million in mobile payments per day.

Moreover, Chambers is working to ensure PayPal remains in the game. PayPal owner eBay announced earlier this month it acquired mobile payments technology firm Zong for approximately $240 million in cash, and said Zong would be integrated into its mobile payments business.

But Chambers isn't alone in the market for mobile payments. A wide range of companies are poised to attack the mobile payments arena, from Google (NASDAQ:GOOG) and Research In Motion (NASDAQ:RIMM) on the handset side to Sprint Nextel (NYSE:S) and Isis (a joint venture among AT&T Mobility (NYSE:T), Verizon Wireless (NYSE:VZ) and T-Mobile USA) on the carrier side to Visa and American Express on the credit side. Each player is hoping to carve out a niche between mobile users and the goods and services they want to pay for with their phones.

Chambers has plenty of experience at eBay to parlay into her assignment. According to her public profile on LinkedIn, Chambers has been with the auction website since 2005 in a variety of roles, including manager of corporate strategy and chief of staff. Chambers has been working in PayPal's mobile business since late 2009.
