Costco’s fast lane: New pre-scan checkout, mobile app and 8-second automated pay stations aim to speed shopping without raising prices
Costco is rolling out a hybrid pre-scan checkout in 27 stores starting May 2025, letting members scan items with the Costco mobile app, get an employee-verified QR code and pay at automated stations in about eight seconds.
- Hybrid pre-scan pilot: Members scan with the Costco mobile app, receive an employee-verified QR code, then pay at automated kiosks averaging ~8 seconds per transaction.
- Rollout and reception: Pilot began mid-2025 and expanded to 27 stores in May 2025 with improved traffic flow and positive member feedback.
- Strategic aim: Management frames the program as a way to boost checkout speed and employee productivity while preserving Costco’s low-price model.
The system: how Costco’s pre-scan checkout works
Costco’s model blends member self-service and employee oversight. Members use the Costco mobile app to scan barcodes as they shop. When ready, the app generates a personalized QR code. An employee verifies the scanned total and cart contents, then the member completes payment at an automated pay station. Early pilots report an average payment time of about eight seconds per transaction.

Why this is different from past tests
Costco previously tested self-checkout methods, such as handheld scanner guns at select locations, but technical issues limited adoption. The new pre-scan approach keeps employees in the loop for verification rather than moving to fully unattended lanes — a human check intended to reduce theft, scanning errors and complaints from members with large carts.

Financial and strategic context
The rollout arrives as Costco posts strong sales and seeks efficiency gains that don’t undermine its low-margin, membership-driven model. In Q2 2026, Costco reported net sales of $68.24 billion (up 9.1% year over year) and net income of $1.36 billion (a 13.6% gain), aided by a membership price increase.
Leadership under CEO Ron Vachris and CFO Gary Millerchip is emphasizing technology that complements warehouse operations. Millerchip said the changes — including mobile wallet improvements, pharmacy pay-ahead and employee pre-scan tech — are producing “meaningful improvements in the speed of checkout and employee productivity.”

Margins and member value
Costco’s model depends on low product margins — roughly 14%–15% — plus membership fees, versus typical grocery product margins of 25%–35%. Executives say the goal is to boost speed and convenience without eroding the value members expect.

Consumer trends and generational split
Surveys show a generational divide: about 43% of shoppers prefer self-checkout overall, with 53% of those aged 18–44 favoring DIY lanes. Older shoppers (55+) generally favor manned lanes, especially when carts are large — a key factor for Costco.

Digital and AI plans
Costco is also testing personalization and AI-driven features on its e-commerce platforms. Executives say early personalization upgrades are resonating with members and beginning to influence online sales growth; they view AI as a potential habit shift that complements Costco’s value focus.

Concerns and critiques
Critics warn automated pay and self-checkout can shift work onto customers and produce long lines at DIY lanes. Early 2020s tests had inconsistent results when scanners lagged. Public data is limited on long-term staffing impacts; online videos and commentary debate whether automation reduces paying jobs or reshapes duties.

What executives say
“In digital, we continue to make strides with our roadmap to deliver a more seamless experience for members in warehouse and online. In the warehouses, we are achieving meaningful improvements in the speed of checkout and employee productivity, both as a result of our mobile wallet enhancements, pharmacy pay ahead and the rollout of employee pre-scan technology.” — Gary Millerchip, CFO
Millerchip noted that automated pay stations are delivering average transactions around eight seconds and that member feedback has been strong. (Q2 earnings call, March 5, 2026)

Evidence and open questions
The pilot ran in a few dozen stores since mid-2025 and formally expanded to 27 stores in May 2025. Costco hasn’t given a nationwide timeline. Early signals point to better traffic flow and speed, but unanswered questions include handling of very large carts, returns, membership disputes and long-term effects on front-line staffing and hours.

How members will use it: Costco mobile app and QR code verification
The Costco mobile app is central: scan item barcodes while shopping, then present the app-generated QR code at an employee verification station. That employee pairs the member’s identity with the scanned cart total for fast payment at the kiosk. The combination of mobile pre-scan, QR verification and automated pay is the pilot’s core value proposition.

Implications for Paso Robles, California
Economic impact
Local Costco members can expect faster visits if the system expands to nearby locations; shorter checkouts could encourage more frequent trips and additional local spending on food, fuel and services tied to warehouse visits. If automation scales broadly, there may be modest shifts in labor demand in Paso Robles’ retail and service mix.
Political consequences
Conservative local leaders may view the changes as private-sector innovation that preserves low prices. Because the hybrid model retains employee verification, wholesale job-loss concerns may be mitigated — but if automation reduces hours or entry-level roles, it could become a local policy issue.
Social effects
Older shoppers in Paso Robles may still prefer manned lanes. Costco’s retention of employee verification should help seniors and large-cart shoppers, but the generational split means stores must continue serving both groups.
Cultural relevance
Residents value time- and money-saving solutions. A faster checkout that preserves low prices aligns with local priorities, though trust will depend on clear communication and smooth rollout.
Practical applications for residents
- Update the Costco mobile app and learn in-warehouse scanning steps to use pilot lanes efficiently.
- Look for signage and staff assistance during rollouts; staffed registers will likely remain for shoppers who prefer human lanes.
- During early deployments, allow extra time during peak hours and watch for pilot lanes.
