Google Pay

 Google Pay  is a payment service that lets you send money to someone using their email address or phone number. Payments can be sent through the app.

Rebranding and website takedown
The service was renamed when the Google Wallet and Android Pay services were combined, pivoting more to focus more on purchases. This lead to the removal of the web UI and Gmail integration. From the app, users can still generate a link to share for payments, though the link opens the Google Pay app.
