2D matrix code: How to successfully switch from barcodes to GS1 DataMatrix codes – Aldi as an example

🌐 Digitalization and automation are advancing in almost every industry, and retail is no exception. One of the most significant developments in this area is the switch from traditional one-dimensional barcodes (EAN/UPC) to two-dimensional (2D) barcodes such as the GS1 DataMatrix code. This transition is being driven by GS1's global "Sunrise 2027" initiative, which aims to enable all point-of-sale systems worldwide to read and process 2D codes by the end of 2027. Companies like Aldi are already well into this transformation process and are relying on innovative solutions to meet the demands of the future.

🖋️ Why switch to the GS1 DataMatrix code?

The GS1 DataMatrix code offers numerous advantages over conventional barcodes. It is not only technologically more advanced, but also enables more efficient process design throughout the entire supply chain and in retail. The most important advantages at a glance:

Higher information density

Unlike traditional barcodes, the GS1 DataMatrix can store not only the GTIN (Global Trade Item Number) but also additional information such as expiration dates, batch numbers, or serial numbers. This enables more precise traceability and quality control.

Space saving

The compact design of the code allows it to be applied to smaller surfaces such as packaging or directly to products – for example, by laser engraving.

Fault tolerance

Thanks to integrated error correction, the code remains readable even if damaged.

360° scanning capability

The GS1 DataMatrix code can be scanned from any direction, which significantly increases efficiency at checkouts and in logistics processes.

Web connectivity

The GS1 Digital Link allows products to be linked to online resources such as detailed product information or recall details.

These properties make the GS1 DataMatrix code a key building block for digitalization in the retail sector.

🚀 Steps to a successful transition

The introduction of the GS1 DataMatrix code requires a systematic approach to overcome technical, organizational, and communicative challenges. Here are the essential steps:

🔍 1. Analysis and Planning

The first step is to identify suitable products for the introduction of the new code. Companies should work closely with their supply chain partners to establish a clear timeline for the transition. A thorough analysis will help identify potential obstacles early on and develop strategies to overcome them.

⚙️ 2. Technical Preparation

The introduction of the GS1 DataMatrix code requires investment in new technologies:

•  Printing systems must be able to apply 2D codes precisely.
• Scanners and cash register systems need to be upgraded accordingly.
• The use of standardized data identifiers (Application Identifiers) makes it possible to securely encrypt additional information in the code.

🔬 3. Conduct pilot projects

Pilot projects are essential for testing the implementation of the new code under real-world conditions. Companies can initially mark selected products or product groups with the GS1 DataMatrix code and verify its functionality. Challenges and solutions identified during these tests serve as a valuable foundation for the subsequent rollout to larger product volumes.

Aldi has already begun using such technologies. For example, frozen pizzas and other products feature QR codes or similar 2D codes such as the ALDI Transparency Code (ATC). These codes allow customers to access information about a product's origin and supply chain – an important step towards greater transparency and sustainability.

🔗 4. Integration into existing processes

Integrating the new code into existing business processes is a crucial factor for success:

•  Employees need to be trained in the use of the new technologies.
• IT systems need to be adapted to process the additional data from the GS1 DataMatrix code.
• Processes along the supply chain need to be optimized in order to fully benefit from the new opportunities.

🗣️ 5. Communication with trading partners

A smooth transition requires close cooperation with trading partners:

• Partners must be informed about the planned changes.
• It should be ensured that their systems are also compatible.
• Joint training sessions and test runs can help to identify potential problems early on.

📦 6. Dual labeling during the transition period

During the transition phase, it may be necessary to apply both the traditional EAN/UPC barcode and the new GS1 DataMatrix code to products in parallel. This ensures compatibility with older systems and facilitates the gradual transition.

🎯 Challenges during implementation

The switch to the GS1 DataMatrix code also brings challenges:

Investments in technology

Companies need to invest in new printers, scanners, and IT systems. These costs can be a particular hurdle for smaller businesses.

Coordination along the supply chain

Close coordination between manufacturers, suppliers and retailers is necessary to avoid inconsistencies.

Employee training

Employees need to be trained in the use of new technologies in order to minimize errors and increase efficiency.

Despite these challenges, the advantages clearly outweigh the disadvantages: The GS1 DataMatrix code enables higher data density, better traceability and improved efficiency – both at the checkout and throughout the entire supply chain.

🌟 Example Aldi: Pioneer in digitalization

Aldi provides a prime example of how companies can benefit from the introduction of new technologies. With the ALDI Transparency Code (ATC), the company already offers its customers the opportunity to access detailed information about products – such as production location or sustainability aspects. This transparency not only meets the growing consumer demand for more information but also strengthens trust in the brand.

Furthermore, Aldi uses 2D codes to increase efficiency at the checkout: 360° scanning speeds up the checkout process, reducing waiting times and improving customer service. At the same time, the higher information density of the code facilitates internal processes such as inventory management and traceability.

🏁 A step towards the future

The switch from traditional barcodes to the GS1 DataMatrix code marks a significant milestone for the retail industry. Companies like Aldi are already demonstrating the potential of this technology – from more efficient processes and greater transparency to better meeting customer needs.

To successfully implement this transformation, structured planning is essential: from technical preparations and pilot projects to employee training and close collaboration with trading partners. Although the initial implementation requires investment, it pays off in the long run through increased efficiency and competitive advantages.

With an eye toward “Sunrise 2027”, companies should start adapting their systems and preparing for the new standards early – because those who act now will be able to benefit sustainably from the advantages of this technology.
