Costco Implements Spot Checks to Deter Membership Sharing at Self-Checkout

Costco is cracking down on the enforcement of its current membership rules to prevent revenue and profit loss caused by shared memberships. The retailer will conduct spot checks at self-checkout counters to discourage non-members from using borrowed membership cards. Costco requires shoppers to show their ID cards before entering the store and when checking out, but some shoppers were able to borrow someone else's membership card and use the self-checkout counter to purchase items without getting caught.
