Why the 2D barcode is the future of traceability

For over 50 years, the linear barcode has been a mainstay of global logistics, offering speed and accuracy in product identification. As the amount of information required on each product increased to protect consumers and businesses, a technological breakthrough became necessary: the transition to 2D barcodes. GS1, the global leader in business communication standards, is driving this transition with the ambitious goal of completing this migration by 2027. This innovation represents a unique opportunity to optimize the supply chain and improve the customer experience.

The 2D barcode does not just identify a product, but is a true container of complex data, offering detailed and easily accessible information. In addition to the classic GTIN (Global Trade Item Number), an internationally recognised unique product identifier, the 2D barcode can include:

• Traceability data: lot number, expiry date.
• Consumer information: ingredients, allergens, nutritional values.
• Sustainability: information on packaging disposal and the use of recycled materials.
• Digital links: instant access to videos, reviews or web information pages.

Due to their two-dimensionality, these codes take up less space and are more reliable than linear codes, even on curved or narrow surfaces.

There are two main types of 2D barcodes:

1. GS1 DataMatrix: This code consists of cells, or black and white dots, arranged in a square or rectangular pattern. Its error-correcting ability makes it ideal for applications on small surfaces or curves, and ensures reliability even if the print is damaged.
2. QR Code: Easily readable by smartphones, this format allows consumers to connect to digital content, such as the GS1 Digital Link, to link the product to personalised digital content.

With the GS1 Digital Link, each 2D code contains a unique URL that links to a customised web page, offering updatable information such as usage instructions, nutritional details or promotions. This system turns packaging into an interactive channel, enabling real-time data updates and enhancing the consumer experience. Companies can use this technology to communicate in innovative ways, optimising transparency and strengthening the bond with customers by making each product more accessible and informative.

The migration to 2D codes does not involve a total infrastructure revolution, but a strategic upgrade. Many point-of-sale scanners are already set up to read two-dimensional codes, requiring only a software upgrade to handle the additional volume of data.

ZANASI is at the forefront in supporting companies in this transition, providing:

• Reliable and customisable marking systems.
• Technical consultancy to integrate 2D codes into existing processes.
• Solutions to improve operational efficiency without interrupting operations.

The 2D barcode brings significant benefits to every stage of the supply chain:

• Manufacturers: easier handling of dynamic data, reduction of errors and optimisation of production processes.
• Retailers: fast and accurate scanning, minimisation of errors and increased efficiency in shop operations.
• Consumers: increased transparency and access to detailed information on ingredients, origin, nutritional values, sustainability and more, turning the label into a true information window.

The 2D barcode is not just a technological choice, but a step towards a more efficient, transparent and sustainable system. With a simple scan, essential information on safety, nutrition and recyclability can be accessed, improving the entire customer experience and contributing to a more connected and responsible economic system.

The move to 2D barcodes represents a unique opportunity to innovate and improve business processes. Investing in this technology today means competitiveness, transparency and sustainability for tomorrow.
