Costco Tests New “Scan & Go” Checkout System to End Long Lines

Costco is testing an innovative “Scan & Go” checkout system in a bid to eliminate the long lines that have long frustrated its loyal members. In response to repeated customer feedback, the retail giant is piloting a mobile solution that allows shoppers to scan items with their smartphones as they shop, build a digital cart, and pay directly via the app—bypassing the traditional checkout line altogether.

How the System Works

The new system works by having customers download the Costco app and register at the store’s dedicated Scan & Go entrance, where a QR code enables them to start a digital shopping session. As members add items to their cart, they simply scan each product’s barcode to create an electronic list. Once shopping is complete, members can pay directly in the app or complete their purchase by presenting a QR code at a specially designated Scan & Pay kiosk. Certain items, such as alcohol and hazardous materials, will still require a visit to the conventional checkout lane.

Early Success and Member Excitement

During a recent fiscal call, CEO Ron Vachris indicated that early trials of the Scan & Go system have yielded very positive results. Members who participated in beta tests praised the technology for significantly reducing wait times—an improvement that not only increases convenience but also enhances the overall shopping experience. With feedback already trending favorable on social media, many Costco shoppers are eagerly anticipating a wider rollout of the system.

A Strategic Move in a Competitive Market

This test is part of Costco’s broader digital evolution, reflecting a growing trend among retailers to adopt technology that speeds up transactions and improves customer satisfaction. Following in the footsteps of competitors like Sam’s Club, which has successfully integrated similar systems since 2013, Costco’s investment in digital engagement underscores its commitment to innovation. The company aims to use these positive early results to potentially phase out traditional self-checkout lanes across many of its locations.
