Watch: Walmart Retail Theft Barcode Switching Caught on Camera
Note: Pay close attention to the timestamp at 00:03:17 in the transcript where the officer notes he can see the little piece of tape still stuck to the suspect’s index finger.
The Surveillance: “Something Weird” at Checkout
Loss prevention officers at the Walmart on Smith Road were performing their normal duties when a shopper’s behavior caught their eye. Aileen Machin-Resto was scanning a large amount of clothing, which staff noted is often a red flag for potential theft.
As they watched the register’s digital readout, the numbers didn’t add up. Expensive clothing and cosmetics were appearing on the screen as “45CT BOBBIES” with a price tag of only $1.18.
Full Story: The Bobby Pin Barcode Trick
The incident unfolded rapidly as St. Charles Police Officer Nickel arrived at the scene. Upon arrival, he found Machin-Resto in the asset protection office with two store employees.
According to police reports, Machin-Resto had two separate groups of items: a shopping cart of paid merchandise and a basket of items that were improperly scanned. The “trick” was simple but effective until the cameras caught it.
“She has like, her own barcode,” a store employee explained to the officer. “Instead of, like, scanning the actual item, she scans that barcode”.
The suspect reportedly admitted to the act almost immediately. “I threw it away,” she told the officer before even being questioned, referring to the barcode. Later, she confessed she had taken a barcode from a package of bobby pins and used tape from the customer service desk to stick it to her finger.
The Evidence: 13 Items and a Hidden Barcode
The scale of the Walmart retail theft barcode switching became clear when the officer reviewed the receipt. A total of 13 different items had been scanned using the fraudulent “bobby pin” code.
The items recovered ranged from cosmetics to clothing and kitchen utensils. While the suspect paid $1.18 for each, the actual values were much higher, including skin creams worth over $20.00.
During a custodial search, Officer Nickel found the smoking gun: a small barcode labeled “0-4145706088-9” secured to a piece of tape inside the suspect’s jacket pocket.

Frequently Asked Questions: Understanding the Charges
What exactly is “Barcode Switching” under Illinois law?
In Illinois, barcode switching falls under Retail Theft (720 ILCS 5/16-25-A-2). It occurs when a person intentionally alters, transfers, or removes a label or price tag to attempt to purchase an item for less than its actual cash value. In this specific case, the suspect is accused of using a bobby pin barcode to scan 13 different items for $1.18 each instead of their marked prices.
Is barcode switching considered a felony or a misdemeanor?
The severity of a retail theft charge usually depends on the value of the property
. For this incident, the total value of the 13 improperly scanned items was calculated at $144.60 (before tax). Because the amount was under the statutory threshold for felony theft, the suspect was processed for Misdemeanor Retail Theft.
Can I be arrested even if I paid for some of the items?
Yes. In this case, the suspect stated, “I paid for almost everything,” and store staff confirmed that some merchandise in her shopping cart was purchased legitimately. However, because 13 specific items were identified as being scanned with a “re-tagged barcode,” the police had sufficient grounds to perform an arrest for the theft of those specific goods.
What does it mean to be “Trespassed” from a business?
Being trespassed means you are officially warned that you are no longer allowed on a specific property. Following this arrest, the suspect was advised by Walmart staff that she was trespassed from the St. Charles location. If she returns to that store, she can be arrested immediately for Criminal Trespass, regardless of whether she intends to shop or pay for items.
What is “Personal Recognizance” regarding a court date?
When a suspect is released on personal recognizance, it means they are allowed to leave police custody without paying a cash bond. The suspect in this case was provided with documentation for a court date on February 26th, 2026, and released on her “word” or promise to appear in court to face the charges.
Conclusion & Current Status
Aileen Machin-Resto was processed and released on personal recognizance. She has been officially trespassed (banned) from the St. Charles Walmart location. Her court date is set for February 26th, 2026, at the DuPage County courthouse in Wheaton.
