Costco tests lightning-fast pre-scan checkout and automated pay stations in bid to cut queues to eight seconds
Costco is piloting a hybrid pre-scan checkout and automated pay stations in 27 U.S. warehouses, using the Costco app to pre-scan items and generate personalized QR codes — targeting average transaction times of about eight seconds.
- Hybrid model: Employee-accelerated pre-scanning + automated pay stations + mobile-wallet features being piloted to speed lanes.
- Pilot scope & timing: Tests began in May 2025 at 27 U.S. warehouses; no nationwide rollout date announced. Sources include The Takeout and Sporked.
- Speed claim: Early data show automated transactions averaging roughly eight seconds, with improved traffic flow and positive feedback (The Takeout).
- Leadership push: New leadership under CEO Ron Vachris and CFO Gary Millerchip is pressing digital upgrades to lift productivity without altering Costco’s low-margin model (Sporked).
How the Costco pre-scan system and automated pay stations work
The pilot asks members to scan item barcodes with the official Costco app while they shop. Scans produce a personalized QR code showing the shopper’s cart total and an itemized list. At the front, an employee verifies the pre-scan — performing a quick barcode or cart check — then the customer pays at an automated pay station. The process is designed to preserve employee oversight while shifting payment into fast kiosks (The Takeout; Sporked).
Pilot results and member reaction
Costco’s initial data from the 27-store pilot show average automated transactions taking roughly eight seconds. CFO Gary Millerchip told investors on the March 5, 2026 Q2 earnings call that early results “are improving the flow of traffic, and we have received great member feedback.” He cited mobile wallet improvements, pharmacy pay-ahead and “employee pre-scan technology” as contributors to faster checkouts and higher employee productivity (The Takeout).
Member reaction has been reportedly positive where the system runs smoothly. The hybrid approach is intended to avoid issues that hindered earlier self-checkout rollouts — technical glitches and inconsistent experiences — by keeping staff involved (Parade; The Takeout).
History: why Costco is trying a different model
In the early 2020s Costco experimented with self-checkout terminals and scanner guns across many U.S. warehouses. Results were mixed: some shoppers appreciated shorter waits, while others complained about machine problems, long bagging times, or handling very large carts. Those mixed outcomes likely guided the shift to a hybrid pre-scan system that retains employee verification rather than pure automation (Parade; The Takeout).
Leadership strategy and digital push
Under CEO Ron Vachris and CFO Gary Millerchip, Costco is pairing its bulk, low-price model with smarter digital tools. Millerchip told investors the company is “rolling out new personalization capabilities” on its digital sites that support e-commerce growth, and that Costco is exploring AI partnerships to enhance personalization (Sporked).
Cost structure and member loyalty
Costco maintains lower product margins (~14–15%) compared with many grocers (25–35%), relying on membership fees and volume to sustain margins. That discipline, along with recent membership price increases, contributed to strong Q2 2026 results: net sales up 9.1% to $68.24 billion and net income up 13.6% to $1.36 billion, giving the company space to test systems and invest in e-commerce (The Takeout).
Industry trends and the generational divide on self-checkout
Data from the The Takeout summary of the NCR Voyix Digital Commerce Index highlights a generational split: 43% of U.S. consumers prefer self-checkout, rising to 53% among shoppers aged 18–44, while those 55+ favor manned lanes. Costco’s pre-scan aims to bridge these preferences by enabling fast lanes for app-first shoppers while keeping staff for larger or complex purchases.
Questions raised: jobs, privacy and practical limits
The pilot prompts practical and ethical questions:
- Jobs: Will faster pay stations reduce frontline roles or shift employee duties toward verification and floor support? Costco emphasizes employee involvement, but long-term staffing impacts are unclear.
- Shrink & verification: The system depends on accurate scanning; effective verification steps will be critical to limit shrink and scanning errors.
- Privacy & data: App-based scanning collects behavior data that ties into personalization plans; Costco has not disclosed detailed data governance policies for the pilot (The Takeout; Sporked).
Operational limits: carts, bulk items and edge cases
Costco customers often buy pallets, bulk items or large electronics that are hard to scan by hand. Older shoppers with very large carts may prefer human lanes for assistance with discounts, returns or special handling. The pilot retains employee verification to handle these edge cases, but scaling across formats and inventory types remains an open question (Parade; The Takeout).
Implementation timeline and what Costco has said
Testing began in May 2025 at 27 warehouses. CFO Millerchip discussed the initiative on the Q2 2026 earnings call (March 5, 2026), but Costco has not announced a national rollout date. The company reports early traffic-flow improvements and favorable member feedback but has not published independent third-party audits or a detailed rollout plan (The Takeout; Sporked).
Implications for the World
Economic impact
If scaled globally, Costco’s model could shorten lines and increase sales per hour at warehouses, pressuring rivals to improve checkout speed without raising prices — potentially benefiting consumers but heightening competition for local grocers (The Takeout).
Political and labor considerations
Governments and labor groups will likely monitor whether automation reduces roles or simply reshapes them. Policymakers may press for transparency on workforce impacts and retraining plans; Costco’s employee verification element could ease some concerns but not all (The Takeout; Sporked).
Social and consumer effects
The pre-scan model favors younger, app-first shoppers while preserving options for older shoppers who prefer staffed lanes. For equitable adoption, retailers must provide clear signage, staff assistance, and multiple payment options to serve customers without smartphones (The Takeout / NCR Voyix Digital Commerce Index).
Cultural relevance & practical applications
In regions where shopping is social or ritualized, removing human touchpoints can backfire. Costco’s hybrid approach — keeping staff visible for verification — may better preserve the chain’s community feel while modernizing operations. Large-format retailers and busy urban hubs can learn from Costco’s pilot, but success depends on robust apps, reliable hardware, thorough verification procedures and clear data policies (The Takeout; Sporked).
“We are improving the flow of traffic, and we have received great member feedback,” — CFO Gary Millerchip on the Q2 2026 earnings call (March 5, 2026) regarding the pre-scan pilot (The Takeout).
