HopePower.com, miestny dodávateľ elektriny, najal Karolínu ako marketingovú špecialistku. Doteraz bol ich web iba informačný a plný statických stránok. Karolína web inovuje tak, aby zahŕňal online nakupovanie pomocou procesu platby v súlade s PCI. Odporúča bežnú možnosť dokončenia nákupu pomocou kariet Visa a Mastercard, ale nepáči sa jej, ako dlho zákazníkovi trvá takáto platba. Ktorá z platobných možností umožňuje zákazníkom dokončiť platbu pomocou karty Visa uloženej v ich účte Gmail?

Google Pay allows users to store payment methods, including Visa cards, within their Google account (associated with Gmail). This enables a faster checkout process on websites that support Google Pay, as users don't need to manually enter card details each time. PayPal is a separate payment platform that also allows stored cards but is not directly linked to Gmail for card storage. Venmo is primarily a peer-to-peer payment app and less commonly used for website checkouts in this context. Square Wallet (now Square Pay) is a mobile payment app and platform, but it doesn't integrate with Gmail for card storage in the way Google Pay does.
