Google Aims to Speed the Online Checkout Line - New York Times: "In its quest to 'organize the world's information,' Google now wants to keep track of your credit card number and where you live.
Google is charging merchants 20 cents plus 2 percent of the purchase price to process card transactions, less than most businesses pay for credit card processing. Banking industry executives say that credit card processors typically pay MasterCard and Visa a fee of 30 cents and 1.95 percent for every purchase, so Google will be subsidizing many transactions.
What is more, for every $1 a company spends on search advertising, Google will waive the fees on $10 worth of purchases. Factoring in the 2 percent fee, that represents a rebate of at least 20 percent of advertising spending."
