Costco Says Its New Pre-Scan Checkout System Takes 8 Seconds — So I Put It to the Test

Why It Matters

A faster checkout could boost member satisfaction and reduce labor bottlenecks, while signaling Costco’s willingness to modernize its in‑store experience amid growing competitive pressure. Successful scaling may reshape how big‑box retailers balance low‑cost operations with digital convenience.

Key Takeaways

• Pre‑scan aims to cut checkout to eight seconds.
• Employees scan carts while shoppers wait in line.
• Pilot shows 50% success rate in early tests.
• Scanning gun glitches and double scans still cause delays.
• If refined, system may narrow gap with app‑based skip‑line rivals.

Pulse Analysis

Costco’s checkout lanes have long been a pain point for members, especially on weekends when carts snake to the back of the warehouse. The new pre‑scan pilot attempts to streamline the process by having staff scan each item as shoppers queue, theoretically eliminating the time‑consuming unload‑and‑reload step at the register. While the company touts an eight‑second transaction time, real‑world tests reveal a split outcome: some carts glide through, but others encounter system hiccups that force a fallback to traditional scanning. This variability underscores the challenge of retrofitting high‑volume, low‑margin operations with emerging tech.

The initiative arrives as competitors like Sam’s Club have already deployed app‑based scan‑and‑go solutions, allowing customers to bypass lines entirely. Costco’s approach, which still relies on employee labor, reflects its cautious adoption style but also offers a middle ground for members who lack smartphones or prefer in‑store assistance. Early employee feedback points to hardware malfunctions and occasional double‑scans, issues that can negate any time savings and potentially frustrate shoppers. Nonetheless, the pilot’s mixed reception provides valuable data for refining scanning hardware, staff training, and workflow integration before a broader rollout.

If Costco can iron out the technical glitches and achieve consistent eight‑second transactions, the payoff could be significant. Faster lanes would improve member perception, reduce staffing strain during peak periods, and keep the retailer competitive in a market where convenience increasingly drives loyalty. Moreover, a successful model could set a new industry benchmark, prompting other warehouse clubs to explore hybrid pre‑scan solutions that blend human oversight with digital efficiency. The next phase of testing will reveal whether the concept can move from novelty to a scalable asset for Costco’s sprawling network of stores.
