Amid slow adoption, and the loss to two managers, Google is rethinking its strategy for mobile payment system Google Wallet, reports Bloomberg News. The company is considering a revenue-share program with Verizon and AT&T to encourage the two carriers to embrace the technology.

Google hopes the payment system will become a goldmine for the company’s display ad business — targeting ads, promotions, and coupons at consumers, based on their shopping preferences. The carriers, too, see the monetary potential in maintain control of the business, and are working the ISS system. In December, Google claimed Verizon was blocking consumers from downloading Google Wallet on their phones.
