Google Pay update brings Gmail integration, here are its benefits0
9to5google is reporting that Google Pay has been updated with Gmail importing, which means that the mobile payment app will browse through your emails and add the relevant information to its system.
For example, whenever you receive loyalty cards, movie tickets, and boarding passes in the Gmail inbox, they will be automatically added in Google Pay. Keep in mind though that if you delete the email containing the information, it will disappear from Google Pay as well.
The improvement makes it easier to access loyalty cards, tickets, and more without having to go through your emails every time you want to know something about them. It's also easier to find coupons and boarding passes that are being sent to your Gmail inbox and make use of them.
It's worth mentioning that the new Gmail import feature is disabled by default, so you'll have to enable it in Google Pay by heading to Settings / General / Gmail Imports and using the toggle available after the latest update.
