Walmart, Target, and other major retailers have been forced to change the anti-theft measures used in self-checkouts since they were introduced in 1986.
Self-checkout kiosks have evolved to use cameras and other trackers to catch shoplifters as the threat of theft has increased over the last few decades.

Employee-powered buying stations were designed to reduce store labor costs, among other things.
According to a 1988 article in the Miami Herald, the system reduced cashier costs by about 66%.
Originally, they were advertised to stores and shoppers as helping save the store money, save the customer time, and stop pesky shoplifting.
In 1986, Kroger’s stores installed the first self-checkout machines. The project cost him $5 million.


These first editions were called CheckRobots.
They worked with self-scans, followed by customers slipping groceries onto a moving belt and bagging them from the store.
eye for eye
Self-checkout sections originally existed to replace human presence entirely, but are mostly led by store employees who monitor areas to ensure rules are followed. .
People are less likely to steal if they know the scanner has eyes, even if they are friendly.
Still, constant surveillance is grim in its aggressive passivity, James, a 25-year-old cashier at a Washington state store, explained to the outlet.
“You’re trapped in that little place and just standing in the same spot for up to eight hours a day will kill your legs,” he said.
“And having to deal with so many people just drains your mental batteries.”
He also said that watching self-checkout streams to monitor shoplifting makes him feel like “a shark with blood in the water.”
smart camera
Chains like Walmart have already implemented AI cameras aimed at catching “banana tricks.” It has been known to scan expensive items instead of cheap ones.
James has seen people try to steal a $1,500 grill by turning the barcode into a $5 item, The Guardian reported.
These cameras include misscan detection, explains sociologist Christopher Andrews, who studied kiosks in his 2018 book.
“It turns the leisurely activity of shopping into a semi-TSA airport-style security check,” said Andrews.
weight
It has also become common for self-checkout users to check the weight of items with kiosk sensors.
While this may seem like a necessary feature for weighing produce, it is actually intended to ensure that the weight of the product moves from the point of purchase to the bagging area.
Installing these sensors increases security around the kiosk, but it also increases customer dissatisfaction.
Sensors often believe there is an “unexpected item in the bagging area” and cause an error.
Employee assistance is required to correct this and may delay checkout.
Even as stores try to improve self-checkout security, some thefts are unstoppable.
Institute
Target has its own forensic facility to help catch criminals.
Video analyst Craig Slaine played a key role in tracking down convicted murderer and sex offender Alfonso Rodriguez Jr.
Thrane worked at one of two ANSI-ASQ National Accreditation Board accredited forensic labs headquartered in Las Vegas and Minnesota and operated and funded by Target.
Investigators at a lab near Minneapolis also helped police identify Edwin Hall, 27, as a suspect in the murder of 18-year-old Kelsey Smith, Forbes reported.
Thieves aren’t the lab’s primary focus, but it’s a nod to the resources available for catching lawbreakers.
protected
Target also employs Asset Protection guards who can detain people awaiting police arrival.
Sometimes these guards are obvious to the naked eye


They may also be dressed for pedestrians, like hidden shoppers.
According to a job description on the Target website reviewed by The US Sun, asset protection specialists “mitigate the risk of shortages, prevent, investigate and resolve theft and fraud, and ensure product availability for customers.” It exists to protect profitable sales by
