Which of the following is required when creating a zero total receipt?

Creating a zero total receipt is a specific process that occurs in retail environments, including Costco, often used for a variety of administrative or promotional purposes. When a zero total receipt is necessary, defacing the receipt signifies that the transaction is not a standard sale but rather an acknowledgment that the customer did not purchase any items. This action prevents any confusion over the receipt's validity, ensuring it is clear to both the customer and employees that no transaction occurred.

The other elements related to scanning items, confirming customer identity, or applying loyalty discounts do not appropriately fulfill the requirements for generating a zero total receipt. Scanning all items remains essential in regular transactions but does not apply here, as there would be no items to scan. Confirming customer identity and applying discounts are also processes that benefit standard sales and interactions but are not necessary for creating the specific receipt type related to zero returns or cancellations.
