The new platform simulates the open-ended nature of calling a store to place an order, but includes certain perks of mobile commerce such as stored account information and pictures of products.
Google demonstrated this process by placing an order with Panera Bread through the Google Assistant built into its smartphones and the Google Home speaker.
"The platform handles all of the complexity," said Valerie Nygaard, senior product manager Google, in a presentation at the Google I/O developer conference on Wednesday.
The Google Assistant, representing Panera, suggested menu items with pictures and was able to access Nygaard's stored addresses and payment details without installing an app or setting up a Panera account. It used fingerprint authentication before sending any of this information to the merchant.
"I was in control of what I shared, every step of the way," said Nygaard, who described the process as "super easy, like I was talking to someone at the store. I didn't have to install anything or create an account."
