The integration of Google Wallet and email is predicted to have huge potential provided people are willing to trust the service.
According to a report by Huffington Post, all that a user needs to do is hit the dollar symbol in the attachments and enter the amount.
One can send money to even those who do not have a Gmail account.
This feature will be rolled out to the US Gmail users above 18 years old in the coming months.
The new feature is expected to pose a threat to e-commerce companies like Venmo, which offer money transfer feature through Android and iOS apps, the report added.
