Google Pay lets customers pay online or in apps using payment methods saved to their Google Account. On Chrome and Android, Autofill can enter saved card details at checkout, while the Buy with Google Pay button lets shoppers choose a payment method and shipping address. Android users can tap at store card readers and transit gates or stations, using saved cards, tickets, and other items. Google Wallet can hold credit, debit, loyalty, and travel cards for Google Pay use. Eligible cards may use virtual card numbers to conceal actual card details from merchants during online purchases. At checkout, users may also choose providers such as Affirm, Klarna, or Zip, subject to eligibility. Businesses can add Google Pay API checkout to an app or website, and Google says it charges no additional fee to accept Google Pay, though payment provider processing fees still apply. Google describes payment data as end-to-end encrypted and says it will not sell personal information or transaction history. Google Pay is free, but feature availability depends on region and device; contactless payments require an Android phone with NFC.
