While Google Wallet has been integrated into Gmail on the web since 2013, it has yet to be available for mobile users. Today, Google is officially rolling out the new integration so that users of the Gmail app on Android will be able to send or request money with anyone -- even those who don't have a Gmail email address. TechCrunch reports: The user experience has been designed to make exchanging money as easy as attaching a file, Google explains in its announcement. To access the new feature, you tap the attachment icon (the paperclip), then choose either send or request money, depending on your needs. A pop-up window appears where you can input the amount and add a note, and send. The entire process takes place in the Gmail app -- you don't have to have Google Wallet installed. In addition, recipients can configure it so the money they receive through Gmail goes directly into their bank account. There are no fees involved, notes Google. The goal, seemingly, is to take on quick payment apps like PayPal, Venmo or Square Cash, by offering a feature to move money right within Gmail's app. This could be useful for those times where the money is already a topic of an email conversation -- like when you're planning a trip with friends, or getting the family to go in together on a gift for your parents, for example.
