From Stripes to Scans: The Barcode Revolution and What Comes Next?

For over half a century, the humble barcode has fueled global retail transformation. From speeding up supermarket checkouts to enabling precise inventory tracking, it’s been a silent hero of commerce. But now, a new chapter is unfolding —not about replacing barcodes, but evolving them to unlock greater possibilities.

The barcode story began over 50 years ago, when retail leaders around the world agreed on a single global standard to streamline point-of-sale operations. Before barcodes, checkout clerks manually entered prices, resulting in a slow and error-prone process. Today, a simple barcode scan empowers instant checkout, and is often done by consumers themselves.
It’s hard to imagine a world without barcodes, yet we’re now on the brink of another leap forward.

Consumers are expecting higher information transparency. There are also tightening global regulations on product data, which traditional barcodes can't deliver.
The capabilities of 2D barcodes powered by GS1 go far beyond basic product identification. They can carry detailed information such as:

• Expiry dates and batch numbers for better supply chain management
• Traceability data
• Nutritional facts, allergen warnings, and recipe suggestions

Sustainability information like recyclability 

• Company information 

It’s now the time for manufacturers and retailers to transform. For consumers, it means empowered decision making knowing not just what a product is, but where it came from, how to use it, and how to dispose of it responsibly.

Not anytime soon. While 2D barcodes are gaining traction, especially with the upcoming “Sunrise 2027” when retailers worldwide will be ready to scan them at point-of-sale, 1D barcodes will continue to coexist for the foreseeable future.

We’re entering a transitional phase where products will carry both formats. The next-generation barcodes, 2D barcodes, open the door to a new era of information transparency—enhancing consumer engagement, enabling smarter, more sustainable choices, and shaping future opportunities.
