Send money in Gmail on Android
In fact, there's only one major feature coming to Gmail for Android: the ability to send and request money. Yes, you can now send and request money in your Gmail app on Android, just like you can safely share photos and files on the go.
Also, you can set the recipients to redirect the money you receive directly into your bank account; and all these operations are free of charge. More importantly, you can exchange money even with people who don't have Gmail addresses.
Keep in mind though that for the time being, the ability to send and request money in Gmail is available in the United States only, on the web or Android. Make sure you update your application today if you want to benefit from the new feature.
