What must be scanned to initiate a trial membership at Costco?

To initiate a trial membership at Costco, the trial membership itself must be scanned. This is because the trial membership serves as the starting point for a new member’s shopping experience, allowing them to access Costco’s services and products for a limited time without fully committing to a paid membership right away.

Scanning the trial membership provides the system with the necessary information to track the duration and usage of the trial period and ensures that the individual can take advantage of the benefits of being a member temporarily. While other options may relate to transactions at Costco, they do not specifically pertain to starting a trial membership. The other items like the member card or gift card are relevant to existing members or specific purchases but are not applicable for someone initiating a trial membership.
