Send money
with Gmail
Google Wallet is now integrated into Gmail. This means you can securely send money to friends and family in the U.S. - without leaving your Gmail inbox.
This feature will be rolling out to Gmail users ages 18+ in the U.S. over the next few months. Look for the $ icon in your attachment options. You can also get earlier access if your friends have the feature and send money to you.
