Everyone's favorite smoothie spot is piloting mobile and tablet ordering and four electronic payment systems, including PayPal and Google Wallet. Jamba recently released an iPhone app that links to its point of sale system so customers can order smoothies, pay through PayPal and designate a pick-up time, even the next day. When they get to the store, they can bypass the lines. With one tap--rather than using multiple cards and pieces of paper--customers can pay, redeem coupons and collect loyalty points, says Robert Notte, CTO. "No more Costanza wallet," he laughs, referring to the Seinfeld episode where George's overstuffed wallet throws out his back and then blows apart in the street.
