The landscape of retail is constantly shifting, and few areas reflect this evolution more dramatically than the checkout process. For many years, the self-checkout lane promised a swift, solitary exit from our favorite stores. However, at wholesale giants like Costco, this seemingly simple convenience has grown into a complex system, undergoing significant overhauls that have members debating the balance between speed, security, and the trusted shopping experience.
Initially, the self-checkout process at most retailers was designed for minimal interaction, with a single employee typically on hand to assist with technical glitches or monitor for scanner fraud. Costco, after a brief attempt in 2013, reintroduced these lanes to select locations in 2019, steadily expanding their presence. Yet, this expansion has not been without its challenges, leading the company to implement a series of changes that are now redefining how members conclude their shopping trips.
Recent observations from shoppers on platforms like Reddit reveal a pronounced shift in how these self-service areas operate within some Costco warehouses. Members have reported a distinct departure from the hands-off approach, with employees becoming much more involved in the scanning process. This increased oversight aims to enhance accuracy and reduce issues that historically plagued the self-checkout experience.

Shoppers at certain locations, for instance, are now required to utilize only the tabletop scanner for their purchases, needing employee assistance for any bulky items. In stark contrast, other stores previously offered members access to a handheld scanner, allowing them to ring up items directly from their cart. This disparity highlights an ongoing, evolving approach that varies significantly from one Costco warehouse to another.
One of the more surprising developments for many members has been the direct intervention of employees, sometimes taking over the entire scanning process. Reports describe workers using handheld scanners to ring up every item in a cart, effectively completing the transaction for the shopper. This level of involvement has naturally elicited a wide range of customer reactions, underscoring the divided opinions surrounding these procedural changes.
On social media, the reviews have been decidedly mixed, reflecting the varied experiences members encounter. While one shopper recounted an employee abruptly taking a handheld scanner mid-checkout, another hailed the additional assistance as a “Grade A experience.” This positive account detailed a swift process where an employee handled everything from scanning the membership and credit cards to ringing up items directly from the cart, all completed in under a minute without the need to unload the cart.
Costco’s journey with self-checkout has also contended with unique operational challenges, notably the absence of express lanes. Unlike many retailers that cap items for self-service, Costco initially had no explicit limit on the number of items members could bring through. This policy, or lack thereof, has been a frequent point of discussion among members, given that the Costco website indicates members purchase 16 items per trip on average.

Online discussions have brought to light the practical issues arising from unlimited item counts. One Reddit user pointed out that excessive weight in the bagging area of self-checkout kiosks can cause the system to malfunction, bringing the entire lane to a halt for everyone. Furthermore, the inherent design of these stations means precariously balanced bulky items in the bagging area are prone to toppling, leading to cleanups and further delays.
Beyond operational snags, a fundamental issue for many Costco shoppers revolves around a perceived lack of trust and autonomy. The inconsistency in self-checkout procedures across different stores has inevitably led to comparisons with competing retailers. Many members express a preference for a more trusting approach, allowing greater control over their own scanning.
This sentiment is encapsulated by a user who stated, “I have always wished we the customers had access to the hand scanners, but I was always told that Costco Corporate wants customers to use the table scanner and the employees to use the hand scanners.” This highlights a desire for tools that would streamline the process for them, rather than requiring employee intervention for tasks like scanning large items.

Comparisons frequently surface with rival services like Sam’s Club’s Scan & Go, which permits customers to use a smartphone app to scan merchandise as they shop, completely bypassing traditional checkout lanes. Similarly, retailers that allow customers to use handheld scanners for oversized or bulky items at self-checkout are often cited as setting a higher standard. One shopper humorously remarked, “Your Costco has hand scanners for members? If I want to use the hand scanner I have to take my food to Home Depot,” illustrating the frustration.
In response to these evolving dynamics and member feedback, Costco has rolled out significant self-checkout changes, encompassing new station locations, stricter membership enforcement, and advanced technology. These updates are designed to enhance the overall shopping experience, aiming for faster payments and improved security, directly impacting every member.
One of the most visible changes involves the relocation of self-checkout stations within warehouses. These stations have been moved away from main aisles, a strategic decision intended to improve store traffic flow and create a smoother shopping environment. Many shoppers have lauded this adjustment, with one customer exclaiming, “It’s honestly 100x better,” attributing faster-moving lines to the new layout.

Employees have also noted fewer traffic jams in busy areas, as positioning self-checkout stations further from the main entrance encourages more members to utilize regular checkout lanes. This distribution helps keep primary aisles clear, contributing to a quicker exit from the store for all. However, some initial confusion has been reported, with carts occasionally snaking through snack aisles or blocking entrances during the transition.
Perhaps the most impactful update is the new requirement for members to present both their membership card and a photo ID at self-checkout stations. This stringent rule, necessitating that the names and faces match, is a direct measure to combat unauthorized use of membership benefits. It effectively stops non-members from leveraging borrowed cards, protecting the integrity of the membership model.
This policy directly addresses an increase in non-members attempting to use borrowed cards in the self-checkout lanes, a problem exacerbated by the convenience factor. By requiring photo identification at the registers, Costco aims to deter membership sharing and maintain fairness for all paying members. Signs now remind shoppers that only valid members can make purchases, with a risk of losing shopping privileges for violations.
Costco has also been integrating new technology to streamline the self-checkout experience, most notably with the introduction of the scan & pay feature. This innovative system allows members to scan items as they shop and pay directly through the Costco app, eliminating the traditional receipt check at the exit. Upon completion, a QR code scan at a kiosk validates the purchase, saving time and reducing queues.

CEO Ron Vachris affirmed the positive impact of this technology, noting that it helps speed up transactions and reduce wait times. Over half of Costco shoppers have reportedly downloaded the app, indicating strong member interest in these expedited checkout options. This partnership with Instacart for the scan & pay feature underscores a commitment to making the checkout process as efficient as possible for members.
To further reinforce these new policies and enhance security, Costco is also increasing staff presence in self-checkout areas. These employees are tasked with checking IDs, monitoring stations, and preventing both membership sharing and theft. The company acknowledges a minor rise in shrinkage rates since the introduction of self-checkout, but emphasizes that the issue is being actively managed through a combination of technology and human oversight.
Retail analysts often point out that technology alone is rarely a panacea for all problems. Costco’s strategy reflects this understanding by combining automation with increased staff support and audit steps, ensuring the new checkout process functions effectively and securely for its members. This blended approach seeks to optimize efficiency while mitigating risks.
Another significant discussion point among members revolves around the introduction of item limits at self-checkout stations. While the Costco website’s FAQ doesn’t explicitly state a limit, some stores have posted signs indicating a 15-item cap. Other locations suggest a practical limit of around 20 items, though these limits are generally not strictly enforced and can vary by store.

The underlying rationale for these suggested limits is to keep lines short and ensure a smoother, faster experience for all members, especially those with quick trips. Employees may gently encourage members with full carts to use regular checkout lanes, reinforcing the idea that self-checkout is best suited for low-volume purchases. This helps maintain the intended efficiency of these lanes.
Reddit discussions confirm the community’s engagement with this “unspoken rule.” One user reported an employee scanning all 20 of their items, stating that 20 was “really too many,” despite acknowledging no official policy. While some argue self-checkout should be an “express checkout lane,” others demand clear policy signage if limits are to be imposed. Even opponents of strict limits concede that exceeding about 20 items invariably slows down the process for everyone else.
Beyond efficiency, item limits also serve as a loss prevention tactic, as self-checkout lanes are often identified by Costco employees as areas where the majority of thefts occur. Fewer items reduce the opportunity for high-value products to go unscanned. Furthermore, the physical design of self-checkout stations with limited bagging space struggles to accommodate large orders, as items must remain on the scale until payment is complete.

While many members appreciate the swiftness and convenience brought by these self-checkout enhancements, there is a distinct undercurrent of frustration and confusion. The new station locations, though beneficial for traffic flow, have initially disoriented some shoppers. Members report seeing carts jammed in aisles as people navigate the updated layouts, or lining up in the wrong places due to unfamiliarity with the changes.
Frustrations extend to the increased employee presence, with some shoppers feeling overwhelmed or even judged by staff while using the stations. Employees themselves have voiced grievances, with one commenting that the self-checkout switch-up was “not well planned out.” This sentiment underscores the teething problems associated with significant operational changes.
Beyond the operational, some complaints delve into the auditory experience. Many members share a specific dislike for how the automated voice from the machines pronounces “Costco,” often described as a drawn-out “COST CO.” One employee even quipped, “Employees hate it too… We hear it in our dreams. We’ll hear it in the afterlife, it’ll be on our tombstone.”
Other auditory gripes include the delayed pronunciation of prices, like “$19…99,” and the sheer volume of the self-checkout voice. A common complaint highlights the loud announcement of “CARD NOT ACCEPTED” when a payment fails, causing embarrassment. These seemingly minor details significantly impact the overall user experience, adding to the feeling of an imperfect system.

One of the most significant pain points for many loyal members is the removal of handheld scanners for customer use. These scanners were previously available at some self-checkout locations, allowing quick scanning of bulky items. Their removal, primarily to deter theft, has forced members to manually lift heavy items onto tabletop scanners or wait for employee assistance, leading to considerable frustration.
As one customer lamented, “I just wish they let us have the handheld scanners back. I could bang out a cart in 30 seconds… But now, because there’s just one employee helping eight self-checkouts, I either have to wait five minutes to flag them down to scan my dog food, or I have to lift it out of the cart, and then have the machine yell at me to not put it on the scale.”
Costco is also taking steps to enforce membership integrity at the very point of entry. Beginning in August 2024, the retailer announced the deployment of membership scanning devices at warehouse entrances. Members will be required to scan either their physical or digital membership card’s barcode or QR code to gain entry. Guests must be accompanied by a valid member.

This new policy is designed to reduce membership sharing and ensure that only authorized members access the store’s benefits. Attendants will be on hand to assist with the scanners and to address issues like inactive memberships or the need for a photo ID if the membership card lacks one. The company anticipates that this upfront verification will ultimately lead to a faster checkout process by eliminating the need for further membership checks in line.
Comparing Costco’s self-checkout system to competitors like Sam’s Club and BJ’s Wholesale Club reveals distinct differences. Sam’s Club’s Scan & Go allows members to scan items with a smartphone app and bypass checkout lines entirely, tracking their total in real-time. BJ’s utilizes an ExpressPay app for scanning and payment, requiring a membership barcode scan at the exit for security.
While BJ’s ExpressPay is available in all locations, Costco is currently testing its own scan & go technology. CEO Ron Vachris has described these tests as “extremely successful moving people through the lines and expediting the transactions.” However, for now, Costco’s primary self-checkout method still emphasizes employee involvement and stricter ID verification at the register, rather than a fully autonomous member-driven app-based system.
The broader retail landscape reflects a clear trend towards app-based self-checkout systems and automation, driven by evolving consumer preferences and the competitive pressure from e-commerce. Retailers are increasingly adopting self-service options to enhance efficiency and improve the customer experience, a direction Costco is clearly following.

Looking ahead, Costco is actively developing its own scan and go features for its mobile app. These future updates aim to allow members to scan product barcodes with their phones while shopping and then present a digital list of items to an employee for quick payment. The goal is to further reduce wait times and make the shopping trip even smoother.
While these technological shifts are not dramatic, they are part of Costco’s ongoing effort to refine its approach based on member feedback and operational needs. For members seeking a smoother self-checkout experience in the interim, practical tips include grouping similar items, utilizing the Costco app for membership, choosing quick-pay options like Apple Pay, and always being ready to ask attendants for assistance.

Ultimately, Costco’s journey with self-checkout is a dynamic one, balancing the desire for efficiency and security with the unique needs and expectations of its members. The ongoing adjustments, from stricter ID checks and new station layouts to the development of advanced app features, reflect a continuous effort to provide a valuable and convenient shopping experience in the evolving world of wholesale retail.
