From PC Mag: If you have a payment method stored in your Google account, there's no longer any need to synchronize Chrome on different devices for it to be accessible.
As explained on the Chromium Blog, Google decided to make shopping "fast, seamless, and safe" by tweaking payments in Chrome to be more convenient. In reality, that means payment methods stored in your Google account will be popped up to automatically fill the payment field as long as you are signed into Chrome.
Before now, accessing a stored payment method required using Chrome sync on every device you use. Now, simply signing in to Chrome is enough to make the information available. A stored card will also be accessible wherever Google Pay is accepted.
Making this change doesn't mean your card will be accessible to anyone using your device, though. Even if it's unlocked and signed into Chrome, Google still requires the user to enter a card's CVC number in order for a payments to go through. It's also possible to have more than one card accessible through your Google account and you can manage payment methods at any time by navigating to Google Account > Payments & subscriptions > Payment methods.
