Google's Gemini AI will handle shopping without hopping between sites or apps

Google introduced the Universal Commerce Protocol to let Gemini and AI Mode display purchase buttons that open in‑app checkout using Google Pay and single‑click Google Account login.

Google is rolling out a new shopping approach that keeps product discovery and checkout inside its own AI interfaces. The company calls the system the Universal Commerce Protocol (UCP). UCP is designed to link listings, payments and post-sale support so users can complete purchases in the Gemini app or AI Mode in Google Search. Google says checkout can use Google Pay and that account and payment details will be pulled from Google Account and Google Wallet. Key details: - UCP is described as a new standard covering discovery, purchase and after‑sales support. - In AI Mode and the Gemini app, product listings will show purchase buttons that open an in‑app checkout window. - Google Account login can register users with a single click and Google Wallet supplies payment and shipping details. - Google says UCP was co-developed with partners including Shopify, Etsy, Wayfair, Target and Walmart and endorsed by more than 20 other companies such as Adyen, American Express, Best Buy, Flipkart, Macy's, Mastercard, Stripe, The Home Depot, Visa and Zalando. - The company says PayPal payments will be enabled "down the road" and that the agentic shopping experience will be offered to users worldwide. Summary: The Universal Commerce Protocol is intended to let Google present product recommendations and complete purchases inside Gemini and AI Mode, reducing the need to open seller sites or separate apps. Google says the system supports Google Pay and single‑click Google Account login and that it was developed with major retailers and payment providers. PayPal support and loyalty‑point integrations are mentioned as future additions. The company says the service will be offered globally.
