Google’s mobile payment service has gotten a fair amount of attention from the media, but user and partner adoption has been slow since the service was unveiled nearly a year ago. Google Wallet is the Internet giant’s eWallet offering, which incorporates NFC technology and allows users to pay for purchases using their Android smartphones rather than physical credit cards. According to Bloomberg, Google is now rethinking its service in an effort to bolster adoption. Citing multiple unnamed sources, the site claims Google is currently weighing the possibility of implementing a revenue-sharing model that would give wireless carriers like Verizon Wireless and AT&T a cut of Google’s fees when subscribers make purchases using their Google Wallet-enabled devices. “They are in a bit of a re-evaluation pattern right now,” Aite Group analyst Rick Oglesby told Bloomberg. “It’s going much slower than anticipated.”
