PayPal must now contend with Google. The Mountain View, Calif., Web-search giant, which has terrified Silicon Valley with its ability to quickly create new consumer products and services, is developing a rival service called GBuy. For the last nine months, Google has recruited online retailers to test GBuy, according to one person briefed on the service. GBuy will feature an icon posted alongside the paid-search ads of merchants, which Google hopes will tempt consumers to click on the ads, says this person. GBuy will also let consumers store their credit-card information on Google.

Google said that it has acknowledged publicly on many occasions that it is working on payment products. The company also said it already processes online payments for ad services, as well as fees from consumers who use features such as Google Store and Google Earth. It declined to comment on any pending products.
