Walmart shoppers are surprised to discover that many Great Value products contain hidden barcodes, a technology developed by Digimarc that has been in place since 2019. A viral TikTok video demonstrated how these invisible barcodes allow self-checkout scanners to identify items without needing to directly scan the visible barcode, thereby increasing security and reducing theft. While the technology has existed for five years, the viral interest is a recent phenomenon. Walmart aims to enhance the customer experience while deterring potential checkout fraud.
Walmart is a forward-thinking technology leader with an unwavering focus on customer experience, making it harder for customers to skip scanning at self-checkout registers.
Real ones know almost all great value items have hidden bar codes, revealing covert codes that have been around since 2019, but are just now gaining public attention.
