HopePower.com 是在地的電氣工程承包商，這家公司已簽約聘僱小夏擔任行銷人。該公司的網站一直以來都是用於列載資訊，而且充滿靜態網頁。小夏打算透過符合 PCI 標準的結帳程序升級網站，加入線上訂購功能。有人建議她採用常見的 Visa/Mastercard 結帳選項，但以這類方式結帳會耗費客戶較多時間，她並不滿意。 哪種付款選項可讓客戶使用 Gmail 帳戶中儲存的 Visa 卡片結帳？

Google Pay allows customers to use payment methods, like Visa cards, that are already saved in their Google accounts (including Gmail). This streamlines the checkout process, as users don't need to manually enter card details, addressing Xia's concern about time-consuming transactions. Square Wallet is a mobile payment app, but it doesn't specifically leverage cards saved in a Gmail account. PayPal is a widely used online payment system, but it requires users to log into their PayPal account or enter card details directly, rather than using cards saved in Gmail. Venmo is a mobile payment service primarily for peer-to-peer transactions and doesn't offer direct integration with Gmail-saved cards for merchant checkouts.
