New customer

Learn more about the Click to Pay checkout flow for a new customer.

Overview

For a new customer, the checkout flow begins after they select Click to Pay after entering their payment information and shipping address and selecting card as a payment method. During checkout, they opt-in for Click to Pay by selecting the Remember me option, complete OTP verification, and finalize their order, ensuring a secure and efficient transaction process.

Checkout workflow

  1. The customer proceeds to the checkout and selects card as a payment method option.

    Click to Pay enter email and phone number

  2. The customer enters their email and phone number and selects Continue.
  • When they enter their email, the Mastercard network lookup takes place. If the customer is not enrolled, user registration process begins.
  • If the customer is already enrolled for Click to Pay, the registered user flow will start, check the returning customer flow for the next steps.

  3. Once the customer selects this option, the option Remember me in this browser is displayed.
