The role of the GS1 Data Matrix code in the technical industry
The growing demands of Industry 4.0 and 5.0
The technology industry is undergoing profound change, driven significantly by innovations such as the GS1 Data Matrix Code (DMC). In the era of Industry 4.0 and the emerging concept of Industry 5.0, the demands placed on companies are constantly increasing due to the growing demand for highly digitized, secure, and reliable processes. Products should not only be uniquely identifiable but ideally also integrated into complex IT systems to enable comprehensive data analysis, intelligent automation, and new business models. The GS1 Data Matrix Code makes an indispensable contribution in this context, opening up numerous opportunities for companies—regardless of their size or industry focus—to secure and strengthen their long-term competitiveness.
The GS1 Data Matrix Code as a basis for digital transformation
“The use of the GS1 Data Matrix code in the technical industry plays a crucial role in securing competitiveness in the context of digital twins, IoT, Industry 4.0, and 5.0.” This statement underscores the enormous influence the DMC has gained and explains why more and more companies are taking the step of adapting their processes accordingly. The Data Matrix code is not simply used to identify products. Rather, it creates the foundation for the end-to-end digitization and networking of all information required for manufacturing, delivery, operation, and maintenance.
Compact data storage in the smallest space
A key factor in the popularity of the GS1 Data Matrix code is its format, which can store a wealth of information in a very small space. For complex assemblies or very small parts such as screws or electronic components, all relevant data can be accommodated without major problems. In the technical industry, it is common for a single product to consist of countless individual components. If each of these components is clearly marked and traceable, it is easy to determine when and where it was manufactured, which batch or lot was used, and when, for example, the next maintenance appointment is due. Sensor data can also be accessed and assigned at any time in a higher-level system simply by reading the code and linking the data.
Robustness and reliability under difficult conditions
A key feature of the Data Matrix code is its robustness, allowing it to be read correctly even with minor damage. This is particularly important in environments exposed to contamination, abrasion, or other stresses. In the metalworking industry or for outdoor applications, it is therefore a clear advantage to have a code that functions reliably even under less than ideal conditions. When components are exposed to high temperatures, humidity, or chemical substances, scratches or other wear and tear can quickly occur. Thanks to special error correction mechanisms, the GS1 Data Matrix code ensures that reading remains possible in most cases. This eliminates the need for costly re-marking or replacement of components, saving both money and streamlining processes.
Permanent marking through Direct Part Marking (DPM)
Another relevant point is the possibility of Direct Part Marking (DPM). Here, the code is permanently applied to the component itself, for example, by engraving, laser marking, or dot peening. This ensures that the marking remains intact throughout the product's entire lifespan. This is particularly important for components subjected to high stress or requiring long operating times. Such solutions increase transparency and traceability throughout the entire product lifecycle, which is of considerable importance not only for production and logistics but also for maintenance and claims management.
Standards and efficiency in networked production
The ability to reliably capture and store data is only one side of the coin. To embed this process in a fully networked context, open and established standards are essential. "The GS1 Data Matrix Code is characterized by space efficiency, versatility, robustness, and direct identification." These features have contributed to the DMC becoming a de facto standard in many technical fields. By using the GS1 system, data is uniquely assigned and can be identified globally without overlap. For this purpose, the GTIN (Global Trade Item Number) or a serial number is embedded in the code to uniquely identify each product or component.
Digital Twins: Integration and Optimization
The DMC becomes particularly valuable when integrated into broader concepts, such as the Digital Twin. A Digital Twin is a virtual representation of a real product that contains all relevant information about its properties, condition, and history. This data can be stored in the cloud and networked with other systems. "The unique identification provided by the DMC forms the basis for creating digital twins of products and components." Companies that mark their components with an individual Data Matrix code have the crucial advantage of being able to access up-to-date information at any time. This information can then be used in analyses to, for example, optimize maintenance intervals or predict when a component is likely to need replacing (predictive maintenance).
Digitization through DataMatrix code
The DataMatrix code serves as a unique and unambiguous product identifier, laying the foundation for the development of a digital supply chain. At Schaeffler, each rolling bearing is marked with an individual DMC, enabling seamless traceability from manufacturer to operator.
Creation of digital twins
Using the DMC, companies can create digital twins of their products. These virtual representations combine data from various sources:
- Design data: CAD models and performance parameters
- Production data: Measurement values and manufacturing information
- Logistics data: Location and delivery status of the products
These comprehensive data models enable customers to fully digitally map and simulate their machines.
Advantages of integration
Integrating products into digital twins offers several advantages:
- Optimized maintenance: Maintenance costs can be reduced and the reliability of systems increased.
- Increased efficiency: Customers can quickly evaluate different configurations and optimize performance.
- Improved traceability: The entire life cycle of a product can be tracked, which is particularly useful for maintenance and replacement of components.
- Data-driven decisions: Extensive data enables well-informed decisions in development, production, and operation.
GS1 Standards and IoT
The use of GS1 standards such as the DataMatrix code is crucial for the implementation of IoT solutions:
- Uniform identification: GS1 identification numbers enable the unique identification of objects, machines and people.
- Interoperability: GS1 standards act as a common language for data exchange between different systems and companies.
- Linking with digital twins: The GS1 Digital Link allows physical objects to be linked with their digital representations.
By using these standards, companies like Schaeffler can seamlessly integrate their products into digital ecosystems and thus benefit from the advantages of Industry 4.0.
Seamless integration into IoT systems
Looking at IoT applications reveals another relevant aspect. The Internet of Things (IoT) refers to networked devices and machines that can independently exchange data or trigger actions. When a product is integrated into such an IoT system via a Data Matrix code, information about that product can be automatically collected or updated. For example, a machine in production can recognize which component is currently being installed and adjust the manufacturing process accordingly. "The code enables the seamless integration of products into the Internet of Things by acting as an interface between the physical and digital worlds." These are referred to as "cyber-physical systems," which form a central foundation of Industry 4.0 and 5.0.

Advantages of the GS1 Data Matrix Code in the supply chain
The advantage in the supply chain, meaning the entire supply chain, is equally significant. Products can be scanned with the DMC at every stage of the value chain to determine their current location, their expected arrival time, and which processing steps have already been completed. In industries with particularly high security requirements, such as the automotive or medical sectors, the code makes a significant contribution to counterfeit protection.
“Particularly in the automotive aftermarket, the GS1 Data Matrix is used as a MAPP (Manufacturers Against Product Piracy) code for anti-counterfeiting protection.” This allows companies to protect their customers by ensuring that only authentic components enter circulation. At the same time, it has a positive impact on brand image when products can be demonstrably verified for authenticity.
Schaeffler as a success story of the GS1 Data Matrix code
A prime example of the successful use of the GS1 Data Matrix code is the company Schaeffler, which is internationally renowned, particularly in the field of rolling bearings. Schaeffler relies on GS1 standards to uniquely and permanently identify its products.
“By marking the bearing components with a unique DMC, Schaeffler is creating the prerequisite for generating a digital twin for its rail products.” This demonstrates the importance the digital twin concept has now attained: Schaeffler is thus realizing a flexible, scalable, and holistic business model in line with Industry 4.0. Furthermore, the marking significantly simplifies the exchange of information between component suppliers, vehicle manufacturers, and operators. When sensors and telemetry systems are integrated into the bearings, it is possible to detect in real time whether a component is still in perfect condition or whether signs of wear are emerging.

Industry 5.0: Synergy between humans and machines
This approach, which merges product identification, digital twins, IoT, and cloud-based data processing, is not only forward-looking but also crucial for the vision of Industry 5.0. While Industry 4.0 primarily focuses on networking and automating production, Industry 5.0 places people back at the center. It's about humans and machines complementing and supporting each other. Humans take on creative, planning, or controlling tasks, while machines perform routine work.
The GS1 Data Matrix code acts as a “bridge” between these two worlds. Thanks to its unique identification and transparent data management, people – for example, service technicians or plant operators – can interact efficiently with highly automated systems without losing track of the complex processes.
Predictive maintenance through the integration of sensor data
“Predictive Maintenance: Linking DMC data with sensor data enables predictive maintenance and optimization of operational processes.” This principle demonstrates the enormous potential that arises from the widespread use of such technologies.
Planned maintenance can be scheduled with pinpoint accuracy, for example, when sensor data suggests that certain parts are about to reach their tolerance limits. This minimizes unplanned downtime and maximizes production capacity. Furthermore, real-time information often allows for early identification of whether process optimizations or product adjustments are advisable, preventing costly failures.
Potential benefits for companies through the GS1 Data Matrix Code
Overall, the use of the GS1 Data Matrix code in conjunction with digital twins, IoT, and the principles of Industry 4.0 and 5.0 offers numerous advantages for companies across a wide range of industries. These advantages range from improved traceability and counterfeit protection to the development of new business models. For example, service providers can offer comprehensive product monitoring based on extensive analyses and only bill customers for actual usage – a so-called pay-per-use model. This flexibility and adaptability to changing market conditions proves essential for maintaining a competitive edge.
Importance for large and small companies
Large manufacturers like Schaeffler demonstrate that these standards are practically tested and successfully applied. However, it is also advisable for small and medium-sized enterprises (SMEs) to familiarize themselves with the GS1 Data Matrix code early on. These companies are often integrated as suppliers into global supply chains where uniform standards are used. Those who cannot keep up risk losing important contracts or being excluded from certain markets.
However, thanks to increasing standardization and the availability of professional marking solutions, it is no longer rocket science to mark one's own products with a Data Matrix code and to set up the corresponding processes.
Flexibility and innovation through standardization
The technical industry, in its pursuit of digitalization and competitiveness, cannot do without a tool like the GS1 Data Matrix Code. With this compact, robust, and versatile marking solution, comprehensive information is available to everyone involved in the value chain – from manufacturers and logistics providers to maintenance personnel.
This information can then be integrated into intelligent systems to achieve more efficient processes, improved quality assurance, and innovative business models. “By using the GS1 Data Matrix code in conjunction with digital twins and IoT technologies, companies in the technology industry can sustainably secure their competitiveness and optimally position themselves for the challenges of Industry 4.0 and 5.0.”
The Schaeffler example particularly highlights how a well-thought-out and consistently applied marking concept can usher in a new stage of digitalization and simultaneously open up new value creation potential.
The future belongs to companies that recognize and fully utilize these opportunities – and the GS1 Data Matrix code is more than just a small code on a component. It is the key to a new level of networked value creation and the driving force behind further industrialization, at the heart of which people, machines, and data interact in a highly efficient and intelligent way.
