Google Wallet has been a good way to transfer money to people for a long time, and now, an email won’t even be necessary. In the latest version of the app, you’ll be able to send money to people using just their phone numbers.
When you send money using a phone number, the person will get a text message with a secure link at which they can enter their debit card and have the money will be transferred to it. It looks simple and elegant in design, though we’ll have to see how well it actually works.
To give this a shot, update the app using the Play Store and let us know how it works!
