Costco is quietly rewriting one of the most frustrating parts of a warehouse run: the checkout crush. After years of experimenting with self-checkout and tweaking front-end staffing, the retailer is now rolling out two major changes that promise faster exits and fewer bottlenecks, prompting many members to respond with a simple verdict: finally.
The first shift puts more of the scanning in shoppers’ hands through app-based tools, while the second reorganizes how carts are processed before they ever reach a register. Together, they mark a decisive move toward tech-enabled efficiency that still keeps Costco’s human-heavy service model intact.
Scan and Go moves from pilot to front-line tool
The most visible change is the expansion of Scan and Go, a feature that lets members ring up items on their phones as they shop instead of unloading a mountain of bulk goods at the register. Costco has been testing this approach in select locations, and reporting indicates that the company is now leaning on Scan and Go as one of its two headline checkout upgrades, a shift that directly targets the long lines that have become a fact of life at busy warehouses. In practice, Scan and Go allows shoppers to move at their own pace, then present a digital code at the exit for verification, cutting out the traditional conveyor belt entirely for those who opt in, a process that has been described as moving people through “much better” once it is in place at scale, according to one detailed look at the new checkout system.
Costco’s own executives have framed this as a way to modernize without abandoning the membership-focused model that defines the brand. The Scan and Go feature, which lets shoppers scan items as they pick them up from the shelves, pay in the app, and then show proof of purchase at the door, has been highlighted as the latest tool meant to improve the in-store experience, according to an analysis of the app-based Scan and Go. For a retailer that sells everything from 40-pound bags of dog food to multi-packs of appliances, shifting the scanning burden to the aisle instead of the register is a logical way to keep lines from backing up into the clothing section.
Pre-scan checkout reshapes the front-end flow
Alongside Scan and Go, Costco is also rethinking what happens to carts that still head to a staffed lane. In some warehouses, the company is testing a pre-scan system in which employees begin ringing up items before a shopper reaches the main register, effectively decoupling the scanning process from the final payment step. In Arizona, for example, Costco Wholesale has been piloting a pre-scan checkout strategy specifically aimed at cutting wait times and speeding up the in-store shopping experience, with staff scanning items from carts in a staging area so that payment becomes a quick final step rather than a long ordeal, according to reporting on the Arizona pilot.
This pre-scan approach effectively creates a second layer of checkout, one that is staffed and controlled by Costco employees rather than left to self-service kiosks that the company has largely walked away from. Earlier coverage of Costco’s front-end strategy noted that the retailer tested self-checkout and has largely abandoned that experiment, instead adding a new staffed check option that focuses on checking out faster for members, a shift described as quietly fixing a massive customer pain point at checkout. By combining that philosophy with pre-scan staging, Costco is betting that human-led efficiency will beat a room full of blinking kiosks.
How the tech actually works in the aisles
For Scan and Go to feel like an upgrade rather than a chore, the technology has to be nearly invisible. Members open the Costco app, scan each item’s barcode as they place it in the cart, and pay within the app when they are done, a process that has been detailed in a breakdown of the technology being unveiled in 27 stores where Members use the Costco app to connect directly to the loyalty database and inventory engine, according to a close look at the new technology. At the exit, staff still check receipts and carts, but instead of a paper slip from a register, they scan a code on the phone that confirms payment and item count.
Internally, Costco has described this as part of a broader push to enhance the in-store experience, with a scan-and-go pilot that has improved checkout speed by up to 20 percent at locations that have adopted the technology, and leadership has said member response to this enhancement has been very positive, according to a Dive Brief on the program. Another analysis of the rollout notes that Costco adds Scan and Go technology specifically to tackle the challenge that One of the biggest pain points for shoppers is scanning bulk items, since Many of those products are heavy, awkward, or stacked deep in carts, and the new system is designed to streamline that process for members, according to a detailed report on how Costco adds Scan.
Membership scanners tighten the front door
While the headline changes are happening at checkout, Costco is also quietly tightening control at the entrance, a move that indirectly supports the new tech-heavy flow. The company has told members that Over the coming months, membership scanning devices will be used at the entrance door of local warehouses, and Once deployed, priority will be given to scanning membership cards to confirm that each person entering is a valid member for entry, according to an official explanation of the new entrance scanners. That shift formalizes a practice that was once handled by a quick visual check of cards and helps ensure that the people using Scan and Go or pre-scan checkout are tied to active accounts.
A separate customer-service notice reiterates that Over the coming months, membership scanning devices will be rolled out and that Once the system is in place, staff will use it to verify that each person entering is a valid member for entry, underscoring that the scanners are not just about loss prevention but also about keeping the membership model intact as more digital tools come online, according to the detailed description of membership scanners. For shoppers, that means a slightly more formal check at the door, but it also lays the groundwork for a future in which the same digital identity powers everything from entrance to exit.
Why shoppers are saying “finally”
For years, Costco members have complained that the only thing standing between them and a successful stock-up trip was the checkout line, and the company’s latest moves are a direct response to that frustration. Coverage of the new strategy notes that Costco implements two major checkout changes as customers cry “finally,” with Scan and Go and revamped staffed lanes positioned as the twin pillars of a faster experience, according to a detailed rundown of how Costco implements two. Another breakdown of the same shift emphasizes that 1. Scan and Go is central to the plan, since Costco sells items in bulk and it can be difficult to efficiently and quickly scan those items at a traditional register, especially when a full cart means a long wait with other shoppers standing in line with you, according to a closer look at how Scan and Go.
