10. Stephanie Tilenius, vice president of commerce and payments, Google - 2011 Most Influential Women in Wireless

10. Stephanie Tilenius, vice president of commerce, Google - 2011 Most Influential Women in WirelessAs head of commerce at Internet giant Google (NASDAQ:GOOG), Stephanie Tilenius has her hands full. She's overseeing just about everything involving payments at the company, from Google's Checkout online payments service to Android app downloads to NFC-enabled purchases in brick-and-mortar stores via Google Wallet. And if that's not enough, she's also heading up Google's Offers program--the company's answer to Groupon's local sales deals--as well as the integration of commerce into Google's social-networking gambit, Google+.

"There's going to be a ton of innovation in mobile payments," Tilenius said at VentureBeat's MobileBeat 2011 conference in San Francisco earlier this month.

During her talk there, Tilenius said that 80 percent of commerce is offline and local, and that a big part of her job is to insert Google into those transactions. Android and mobile will represent a key element of Google's strategy in cashing in on shoppers' purchases.

But Tilenius has a notable background to fall back on in her efforts to guide Google's multipronged services. Before she joined Google in 2010, she worked at online auction company eBay, including in eBay's PayPal payments business. According to the New York Times, Tilenius joined eBay in 2001, and before that, she co-founded PlanetRx.com, an early e-commerce company.
