This sequence diagram starts when a user adds an item to their card. When proceeding with the purchase, the user can choose gift wrapping (optional fragment). When it comes to payment, they have two options: card payment and payment by bank transfer (alternative fragment). If the user chooses card payment, they enter their card details and the online store sends the request to the payment gateway. If the customer chooses payment by bank transfer, the online store provides the transfer information to the user. The user pays the bill and gets payment confirmation.
