A WALMART worker has revealed a secret symbol in the Great Value products that makes scanning much quicker.

A viral TikTok made by an employee demonstrates the shortcut that makes the jobs of online pickup and delivery workers much simpler.

The clip shows that Walmart workers can scan the image of products and quickly obtain the product’s information.

“I found a shortcut,” reads a caption in the TikTok video, showing the worker as they scan different product images, with their handheld device quickly obtaining all of the required information. 

Per the video, the hack works for most Great Value products. 

“For most Great Value products, there’s a hidden barcode in the picture of the product,” he wrote.

TikTok viewers dropped different comments sharing their own experiences with the feature. 

“I thought I was insane when I scanned the front of the box and it worked,” a user wrote. 

“Yesss [too] bad they never taught us that.. or anything,” wrote another employee. 

Other users explained how this happens and why it applies to Great Value products.

“It’s called Digimarc, it’s a real thing they have started to add to GV items. *coming from someone who works at a printer*” wrote the user. 

According to the website Labels and Labeling, the Digimarc Barcode is a way of enhancing products with a “digital watermark that’s imperceptible to the human eye, but can be detected by smartphones, computers, and barcode scanners.” 

The watermark is applied to the whole product and allows workers to get their jobs done faster and more efficiently.

It means they don't have to deal with barcodes that have been tampered with or that are inconveniently placed. 

Walmart started working with Digimarc in 2019 and produced a seasonal toy catalog embedded with the technology, allowing shoppers to “scan and shop.”

The technology allowed consumers to scan the catalog with the Walmart app and shop directly from the page. 

Walmart and Great Value have been reached out for comment.
