Secure QR Code–Enabled Anti-Counterfeiting Tax Stamp

This product integrates multiple advanced anti-counterfeiting technologies to create a highly secure, easily identifiable, and unique tax stamp, providing robust protection for tax certificates.

The tax stamp features exquisite 3D embossing technology, where key texts or core patterns undergo precision die-stamping to produce clear and prominent raised and recessed effects. A distinct tactile protrusion is felt when touched, enhancing both the product’s texture and aesthetics. This technology provides an intuitive and difficult-to-replicate physical anti-counterfeiting feature, effectively deterring imitation through ordinary printing methods.

Specific marks (e.g., logos) are printed with colorless fluorescent ink, remaining nearly invisible under natural or ordinary light to preserve the stamp’s design integrity. When exposed to UV light (e.g., a banknote detector), these hidden areas instantly reveal bright, vivid fluorescent patterns with high color brilliance and recognition. This covert design enhances anti-counterfeiting concealment and raises technical barriers, enabling quick preliminary verification by personnel.

Each tax stamp is assigned a dynamically generated, unique encrypted QR code, achieving a true one-item-one-code mechanism. Users can scan the code with a smartphone to directly access the official authentication system, enabling rapid verification of authenticity and traceability of origin. This method ensures efficient, authoritative, and transparent verification.

The three anti-counterfeiting technologies—tactile, visual, and digital—are organically combined to form a triple-layer protection system. This comprehensive approach collectively ensures the safety and reliability of the tax stamp, addressing diverse verification needs while maintaining ease of use.
