Costco pilots 8-second checkout at 27 stores, pairing app pre-scan with employee verification to speed lanes
Costco is piloting a mobile app pre-scan checkout in 27 stores, letting members scan items as they shop and verify totals with a QR code—yielding average automated pay-station transactions of roughly eight seconds, launched in May 2025.
Key takeaways
- 27-store pilot: Mobile pre-scan launched in May 2025 across 27 Costco pilot stores, measuring speed, flow and member feedback.
- Very fast transactions: When using the app pre-scan flow, automated pay-station transactions average roughly 8 seconds.
- Hybrid model: Employees verify QR totals before directing members to fast pay stations—keeping staff involved while shifting routine scanning and payment to tech.
- Financial context: Costco’s low-margin strategy (about 14–15%) and recent membership pricing supported a Q2 boost in sales and earnings while funding digital investment.
How the pre-scan system works
Flow: Members use the Costco mobile app checkout to scan item barcodes while shopping. The app generates a QR code displaying the order total. At the front of the store an employee verifies the scanned total against the QR code, then directs the member to an automated pay station to complete payment. This keeps an employee in the loop for verification while moving barcode scanning and payment steps to the app and terminals.

Pilot rollout and on-floor performance
The pilot began in May 2025 across 27 designated “Costco pilot stores.” Early results show faster lanes, reduced congestion and strong member reception. Company reports cite average transaction times near eight seconds at automated pay stations when members complete the pre-scan flow.

Leadership, strategy and financial context
Executive view: Under CEO Ron Vachris and CFO Gary Millerchip, Costco is shifting to a hybrid checkout model that pairs employees with high-speed technology to protect a low-cost value proposition. Millerchip highlighted the work during the March 5, 2026, Q2 earnings call, tying the checkout changes to broader digital and AI initiatives aimed at keeping prices low while improving the member experience.
“Achieving meaningful improvements in the speed of checkout and employee productivity,” —Gary Millerchip, CFO (Q2 earnings call)
Financials: Costco reported Q2 net sales of $68.24 billion (up 9.1%) and net income of $1.36 billion (up 13.6%), after a recent membership price increase. The company argues these results create room to modernize operations without disproportionately passing costs to members.

Digital initiatives and AI
Costco is expanding personalization and AI-driven features across digital channels. Millerchip said personalization changes on Costco’s digital sites are “resonating well with our members” and starting to boost e-commerce growth. The company views AI adoption in shopping as an opportunity to enhance convenience while maintaining low prices and quality.

Consumer trends and generational split
Data from the NCR Voyix Digital Commerce Index shows a generational split: roughly 43% of U.S. shoppers overall prefer self-checkout, rising to 53% for shoppers aged 18–44. Shoppers 55 and older still favor manned lanes, citing large carts and bulk purchase complexity. Costco’s hybrid pilot aims to offer a faster path for younger, DIY shoppers while retaining employee verification for older members.

Past trials and technical feedback
Costco previously tested self-checkout and scanner guns at some locations with mixed results. Some shoppers praised speed improvements while others reported glitches and frustration. The current pilot blends lessons from earlier trials with an employee verification step intended to reduce errors and member complaints.

Labor and store operations: what changes might look like
The pre-scan system is positioned as a productivity tool rather than a pure headcount reduction. Staff roles will emphasize verification, member service, stocking and loss prevention over routine scanning and cash handling. Industry observers note automation can shift the mix of roles—some retailers reduce payroll, others redeploy labor to customer-facing tasks.

Retail competition and convenience market
Rivals have moved heavily into automation and e-commerce to capture convenience-focused shoppers. Costco’s hybrid model differentiates by keeping employees central to the checkout flow, which could help defend customers who value both speed and human help—especially important for bulk and large-cart purchases.

Costco mobile app checkout and member experience
The app-based checkout expands the Costco mobile app beyond receipts and membership IDs into an in-warehouse tool: scan while you shop, verify with a QR code, finish at a fast pay station. Early member responses in pilot stores report shorter lines and quicker exits.

Implications for Redding, California
Economic impact: Faster checkout can mean less time in line and more predictable trips for families and small businesses that rely on bulk savings. If the pilot expands, local stores may see technology investments and upgrades.
Jobs and staffing: Roles at the Redding Costco may shift from scanning and cash handling to verification, member service and stocking, with an associated need for training. Conservative readers should watch whether roles are redeployed or reduced.
Service for older shoppers: Redding has many shoppers 55+, who often purchase in bulk. The verification step aims to preserve human help for large carts and complex purchases while offering a faster option for tech-savvy members.
Small businesses and local buyers: Shorter wait times at peak hours can make pickup and procurement more efficient for local contractors and small retailers.
Membership value and local prices: Costco’s thin product margins (~14–15%) and recent membership price increases have coincided with higher earnings, which the company credits with funding tech investment without raising product margins—potentially preserving local member value.

What to watch locally
Redding members should look for announcements on whether the local Costco is included in the pilot or a future rollout. Expect in-store signage explaining the app checkout steps, employee verification roles, availability of assisted lanes for large carts and posted training sessions for workers. Member feedback will help shape the breadth of any expansion.
