Security Printing for Tax & Revenue Stamps

Security printing for tax and revenue stamps has moved past the printed mark alone. The technologies below are authentication features that also work as a channel between the brand and the buyer, and they can be layered together on a single stamp.

Dynamic QR codes

A dynamic code is not fixed at print time. It can be updated after the stamp has been applied, so one code can serve personalised product information, a time-limited campaign or a route into a loyalty programme.

Augmented reality

An AR-enabled label turns ordinary packaging into an interactive surface. A smartphone scan opens immersive content such as a brand film or a product tutorial, which gives the verification step its own reason to be used.

Digital watermarks and tamper evidence

Digital watermarks are invisible to the eye and carry encrypted information that a dedicated app can confirm. Tamper-evident labels complete the set: they break or change appearance when someone tries to move them, so the damage itself becomes the signal.

Serialised holography

Combining holography with serialisation gives each unit a unique, visually striking and traceable identity, so a mark can be matched to a single record.
