How do these Digital Wallet applications work?

Downloading and setting up the App

To start using a digital wallet app, you first need to download it from your device's app store. Popular options include Apple Pay, Google Pay, Samsung Pay, and apps from your bank. After downloading, you'll go through a setup process which includes adding your name, and contact info, and verifying your identity. The app will guide you through the steps.

Storing Payment Information

A key feature of digital wallets is the ability to store your payment information for faster checkout.
