The new system requires members to scan their physical or digital membership card before entering the store.
Costco's move aims to prevent non-members from using borrowed membership cards to gain entry to the store.
Members must scan the barcode or QR code on their card at the entrance. An attendant will be on hand to assist.
If a membership is inactive or expired, customers will be directed to the membership counter before shopping.
Members without a photo on their card must show a valid photo ID or get their photo taken at the membership counter.
The new scanning process is designed to be quick, but members should be prepared for the change.
Costco confirmed that the scanning devices will be rolled out over the coming months at all warehouse locations.
Costco encourages members to familiarize themselves with the new system and update their membership details if necessary.
