Digital Twin
A digital twin digitally replicates a physical object or system and links it to relevant information. Its added value lies in bringing together information from different areas and making it usable. This creates a central information base for various applications - from service and maintenance to process optimization and data-driven analysis.
What is a Digital Twin?
A digital twin is a digital representation of a physical product, component, machine, or system. It links the real-world object to the associated digital information, such as technical product information, maintenance data, documentation, operating instructions, or service information. It makes relevant data available throughout the entire lifecycle.

But a digital twin can do much more than simply provide static product information. Depending on the application, simulations and machine learning help analyze data in real time, predict trends, and support decision-making.
Auto-ID technologies, such as RFID/NFC and 2D codes, play an important role in linking physical objects to digital information.
What role do RFID, NFC, and QR codes play?
Various auto-ID technologies can be used to establish a unique association between a physical object and its corresponding digital information.
Which technology is most suitable depends on the product, environment, process, and intended use.
Proper Labeling Is Crucial
For digital information to be used reliably, it must be associated with the correct physical object. A durable label suitable for the specific application therefore serves as a crucial interface between the product and the data.
smart-TEC develops custom RFID/NFC transponders for this purpose, which enable the physical product to be uniquely identified and linked to the digital application.
Our RFID/NFC transponders are fully customizable:
- Design: Shape, material, size, and printing
- Durability: Resistance to chemical exposure and temperature extremes
The corresponding software and data platform can be individually selected and integrated depending on the application and system environment.
Contents of the Digital Twin
Once the unique identity of the physical product is identified, the associated digital information can be retrieved or processed. The data required and how it is provided depend on the specific use case and the software or data platform used.
Possible information contained in a digital twin:
- Product and master data
- Machine characteristics such as production date, model number, or technical parameters
- Maintenance, servicing, and inventory data
- Technical data and specifications
- Operating Instructions and Manuals
- Service Information
- Certificates and Documentation
- Images, Videos, and Documentation
- Product Lifecycle Information
Where are digital twins used?
Linking physical products with digital information opens up numerous possible applications:
Assign maintenance information directly to a component or machine.
Uniquely identify objects and make relevant information available digitally.
Provide instructions, documentation, and additional information with the product.
Digitally map process information and document workflows in a traceable manner.
Unambiguously associate product-related data with a physical product and make it available throughout the product's various life stages.
The specific structure of a digital twin can range from a simple link between a product and digital information to comprehensive, data-driven applications.
What is the difference between a digital twin and DPP?
The digital twin generally refers to the digital representation of a physical object or system and its link to associated digital information.
The Digital Product Passport, on the other hand, takes a more specific approach. It provides certain product-related information in digital form and is particularly relevant in the context of European regulatory requirements.
