Final answer:
In case a member forgets their card, known as an 'oops card' situation, the usual procedure would be to enter the member's card number into the system and proceed with the transaction.
Step-by-step explanation:
If a member forgets their card which is referred to as an oops card scenario, the appropriate action to take would generally depend on the specific procedures of the store or membership program. However, typically, one would enter the member's card number and then hit "Enter" before scanning any items. This allows the system to recognize the member and proceed with the transaction as if the card were physically presented. It's not standard practice to scan a random item or to force the member to retrieve their physical card, as those options either do not solve the problem or create unnecessary inconvenience for the member.
