“According to a post on the official Google Commerce blog, Google Wallet support has been baked into Gmail, so users will soon be able to send each other money by simply shooting each other emails. In the coming weeks and months, a dollar sign will start popping in Gmail accounts of people who already use Google Wallet, and a quick click lets users define the recipient and the amount they’d like to send along as an attachment. Since all of these transactions run through Google Wallet, the usual caveats are in place — sending funds from a connected bank account is totally gratis, but credit or debit cards are subject to an additional 2.9 percent fee.”
