Google has made it possible to send or request money within Gmail on Android devices.
The sender will need a Google Wallet account, but the recipient does not need Google Wallet, nor even Gmail. The service is free for both the sender and receiver. The recipient can transfer the funds from Gmail to the bank account of their choice. The tool is available via the attachment button, which allows people to send/request specific dollar amounts.
The send-money feature will be available in an update to the Gmail app, which is rolling out over the next few days. The service competes with similar offerings from Venmo and PayPal. It is only available in the U.S.
