Ron writes: Starbucks has started accepting mobile payments. Customers can now use the Starbucks Card Mobile app on their iPhone, iPod touch, or BlackBerry at nearly 6,800 company-operated Starbucks stores in the US plus more than 1,000 outlets inside Target stores. To pay with their phone, app users simply select "touch to pay" and hold up the barcode on the screen to the 2D scanner at the register. The app also lets users manage Starbucks accounts and find nearby stores. To start using your device as tender, you can download the app now for iOS and BlackBerry. An Android application is also said to be in the works, but the company has not yet given a release date, and there's no word yet on plans for a Windows Phone version.
