A Google representative declined to comment on the report.
The service, which will reportedly tap near-field communications technology, would allow users to pay for retail purchases by holding the devices up to a specialized reader at checkout counters. NFC technology lets devices exchange information wirelessly with one another over very short distances, about 4 inches.
The report follows a Wall Street Journal report in March that Google was partnering with MasterCard and Citigroup to allow the financial giants' customers to use their debit and credit cards to pay for purchase from their Android smartphones. Google also reportedly paid for the installation of thousands of NFC short-range, wireless point-of-sale systems from VeriFone at stores in New York and San Francisco.
There are currently only two phones with NFC chips installed for sale in the United States: the Google Nexus S and the Nokia C7 or Astound. But many more are expected to be on the way by the end of this year; Forrester researchers expect 40 million to 50 million NFC-equipped phones to be sold in 2011.
