Google has just added more supported merchants for Google Wallet to increase the use of NFC since the first NFC-based Nexus S made its debut several months ago. Now you can make full use of the NFC chip inside your Nexus S and save money with it too. More on that soon, check out the press release:
Today, our partners American Eagle Outfitters, The Container Store, Foot Locker, Guess, Jamba Juice, Macy’s, OfficeMax and Toys“R”Us are rolling out an even better Google Wallet experience. For the first time ever in the U.S., at these select stores, you can not only pay but also redeem coupons and/or earn rewards points—all with a single tap of your phone. This is what we call the Google Wallet SingleTap experience.
As mentioned, you get to save money when using Google Wallet by gong to the "Featured Offers" tab which features offers that are not available anywhere else and you get to save some precious moolah in the process. Google is trying to increase the adoption rate and giving out discounts is definitely the right way to go.
