Retailers throughout the U.S. and Canada are facing a growing epidemic of theft, leading them to adopt a variety of strategies to safeguard their merchandise. Walmart, a key player in the retail industry, is actively refining its methods to tackle these losses, with a particular emphasis on challenges at self-checkout stations.
Recent reports from various stores reveal discrepancies in the enforcement of anti-theft protocols, as both customers and staff have noted that many previously locked display cases are now frequently left open. There are increasing accounts from multiple locations indicating that glass case doors, which are meant to secure products, have been found ajar, and some shoppers have observed that shelves remain consistently unlocked over time.
The reasons behind this shift in security measures are varied, with comments from staff and customers suggesting multiple contributing factors. Some attribute the unlocked cases to mechanical issues, like malfunctioning buttons, while others cite staffing shortages, with employees feeling overwhelmed by the relentless need to open cases, particularly in stores that have only one set of keys available for use. There’s also speculation that this change might be part of a corporate trial to evaluate if the potential losses from theft are counterbalanced by increased sales driven by easier access to items.
The noticeable shift in security practices has sparked diverse reactions among shoppers, with some voicing their annoyance at the cumbersome process surrounding locked merchandise. One frustrated customer remarked, “I, as a customer, have given up,” highlighting the discontent with locking even low-value items like $1.12 facial wipes, as many believe that the hassle outweighs any loss prevention benefits.
Beyond locked cases, Walmart has explored other physical deterrents. Reports from Louisiana described steaks wrapped in steel wire cages as part of an earlier effort to secure high-theft items like meat. More broadly, retailers have rolled out security pegs, security cameras, warning signs, receipt scanners, receipt checks, and shopping carts equipped with locking technology.
The challenge of theft extends to the human element, as reports highlight the use of plainclothes loss prevention workers, sometimes referred to as “floorwalkers.” One individual, who identified as a former Walmart floorwalker, shared experiences of feeling closely watched by multiple suspected workers while shopping with his children, noting he was also stopped at the door to show his receipt. Other shoppers have echoed similar sentiments about feeling profiled or followed.

In response to ongoing theft challenges, including creative methods observed at self-checkouts, Walmart is also turning to advanced technology. The company is implementing a new system utilizing AI and RFID technology. This system involves embedding RFID tags in products that interact with sensors at self-checkout to ensure items are scanned. AI-powered cameras are also intended to monitor activity in real time to identify suspicious behavior.
Furthermore, the retailer is introducing invisible barcodes embedded in the packaging design of some own-label products. These codes, while not visible to the naked eye, can be read by scanners, aiming to improve accuracy and detect items not properly scanned. Walmart has stated this technology focuses on transactions and does not involve collecting personal data.
Other major retailers are also adapting their strategies. Target has reportedly removed self-checkout lanes from all its stores. Sam’s Club is phasing out traditional self-checkouts in favor of AI technology that allows customers to scan items via an app and verify purchases upon exit using AI and computer vision. Walgreens, which has placed many products behind glass, has reportedly found that the practice has not reduced theft and has negatively impacted sales. Costco continues to employ staff at exits to verify purchases against receipts.

Retailers’ combination of adjusting physical security measures, deploying personnel like floorwalkers, and investing in new technologies like AI, RFID, and invisible barcodes reflects the evolving nature of retail theft prevention. The ongoing efforts demonstrate the industry’s search for effective solutions that balance security needs with maintaining a functional shopping experience for customers.
