  • Online paymentWhen checking out on an e-commerce website, select the digital wallet for payment and you will be redirected to the digital wallet's verification page.

  • After a payment request is initiated, the digital wallet communicates with the bank or payment gateway through secure protocols to verify the user's payment information and account balance. Once authorized, the transaction will be processed and completed within the specified timeframe.

  • Notification and Record Management
  • Once the transaction is successful, both the user and the merchant will receive a transaction notification, and the transaction will be recorded in the user's transaction history for future reference.
