What is the correct procedure to perform after scanning a shop card's barcode for a transaction?

After scanning a shop card's barcode for a transaction, the appropriate procedure is to wait for confirmation from the system. This step is critical because it ensures that the system accurately verifies the details of the card, including its validity and the available balance. This confirmation process prevents errors that could arise from attempting to conduct a transaction without proper verification.

Waiting for system confirmation also helps maintain the integrity of the transaction process and ensures that both the member and the system are aligned regarding the transaction details. Jumping ahead to print a receipt or process payment without this confirmation could lead to potential issues, such as processing a transaction on an invalid card or not having sufficient funds. Therefore, the emphasis on awaiting system confirmation is crucial for a smooth and reliable transaction flow in the Costco operational framework.
