Google has rolled out a new cloud-side update to Google Contacts that links it with Google Pay Send, allowing you to send funds to a contact directly from within the app. The feature appears to have a limited rollout at this point so don’t be too surprised if you don’t see the link yet.
If you do have it, you will know when you go to Google Contacts and open up a contact’s information page. There on the menu bar just below their picture, you will find a “$” icon with “Send” under it. Tapping it will prompt you for the email address to send the fund to then finally a Google Pay Send page to input the amount.
