Visa Alias P2P transaction flow

  1. A customer indicates a recipient's phone number.
  2. A merchant submits the number to the eComCharge system to get card details.
  3. The system sends the request to Visa Alias Service, gets card details and a card token linked to the phone number, and sends the token to the merchant.
  4. The merchant initiates a request to get the commission for transferring funds from the source card to the recipient card.
  5. The system notifies the merchant of a commission to be taken, if the P2P transaction is possible.
  6. The merchant informs the customer of the commission.
  7. The customer confirms the P2P transaction. The merchant initiate a P2P transaction request.
  8. The system processes the transaction and notifies the merchant of its status.
