• Costco is testing a feature that would allow customers to scan items in its warehouses and pay for them on their phones, following the lead of Walmart-owned rival Sam’s Club. CEO Ron Vachris offered few details on the technology, but a guide on Costco’s website said customers will receive a QR code after paying that they scan at a kiosk before exiting.

Costco is turning to technology to get its customers out the door faster, a feature pioneered by rival Sam’s Club.
