Holographic anti-counterfeiting label technology generates complex three-dimensional patterns through interference and diffraction, which are difficult to replicate. For example, the microtext on holographic tags can only be recognized by zooming in, and once removed, the tags become invalid, further enhancing their anti-counterfeiting capabilities.
1. Technical principle: Dual anti-counterfeiting and information carrier synergy
The anti-counterfeiting characteristics of holographic labels
Holographic anti-counterfeiting label technology generates complex three-dimensional patterns through interference and diffraction, which are difficult to replicate. For example, the microtext on holographic labels can only be recognized by zooming in, and once removed, the labels become invalid, further enhancing their anti-counterfeiting capabilities.
QR code information
QR codes store product data through encryption algorithms to prevent tampering. Consumers can quickly verify the authenticity by scanning the QR code.
The synergistic effect of technology integration
The combination of holographic labels and QR codes provides dual protection through "optical anti-counterfeiting+digital verification". Holographic patterns and QR codes must be verified to confirm their authenticity, which increases the difficulty of forgery.
2. Core advantages: from anti-counterfeiting to traceability
High security and anti-counterfeiting performance
Optical non replicability: Holographic patterns require high-precision equipment, making replication difficult and costly
Information encryption and layered verification: QR codes combined with encryption algorithms to prevent reuse
End to end traceability
Production stage: Laser label records batch number and raw material information, QR code links to equipment parameters
Logistics stage: Combining RFID and GPS to update transportation status in real time, consumers can query logistics routes
Consumer verification: Consumers can scan the QR code to access complete lifecycle data, such as quality inspection reports and circulation records
3. Typical application scenarios
Food safety
The laser QR code records the entire process from food raw materials to product delivery, preventing certificate forgery. Consumers can verify food batch numbers and distribution routes.
Anti counterfeiting of high-end consumer goods
The combination of laser holographic labels and brand logos can be used for anti-counterfeiting and decoration. The traceability of 'one object, one code' helps to combat parallel imports.
Logistics and Supply Chain Management
Laser labels help with automatic sorting and improve efficiency. In cold chain monitoring, temperature and humidity sensors can ensure transportation compliance.
4. Technological challenges and future trends
Current challenges
Cost control: The manufacturing cost of laser labels is relatively high, and large-scale production is needed to reduce costs
Device compatibility: Old scanning devices cannot read encrypted QR codes and require standardization
Technology integration direction
Artificial intelligence assisted verification: Machine learning can analyze holographic patterns to improve the accuracy of anti-counterfeiting recognition
Blockchain and IoT: Label data can be linked to blockchain and combined with IoT devices to achieve automatic traceability
