Google said several retailers at select locations will let Google Wallet users make mobile payments, redeem coupons and earn rewards points with a single tap of an NFC-ready Nexus S phone.
The new capability is called SingleTap.
Google launched its Google Wallet app on the Sprint's Nexus S 4G smartphone on Sept. 19.
At the time, Google heard criticism that for just one NFC-ready smartphone and that the Nexus S 4G may not complete mobile payments at every retail outlet listed on Google's Web site.
Google said the the new coupon redemption capability occurs with the same tap made for a mobile payment. Therefore, a user could walk into a store and pay for merchandise and at the same time redeem coupons without the need to find them or a rewards card.
