This article explores recent developments around holography technology, from combining origination processes and using AI for hologram detection to developing novel methods for controlling light polarisation.

In the digital age, the security of electronic devices is paramount, not only to safeguard sensitive data but also to ensure the integrity of the hardware itself.

One of the fundamental security features used in manufacturing lottery ticket paper is advanced printing techniques such as watermarking. Further, lottery tickets often incorporate tamper-evident features, which include special adhesives designed to reveal any attempts at ticket tampering or alteration.

Following the expansion of the secure registry of holographic images and its relaunch as the Security Image Register (SIR) last month, the IHMA has announced it will be holding a webinar focusing on the SIR and its benefits for suppliers and their customers on 17 April.

The European Pallet Association (EPAL) UK & Ireland, the umbrella association of licensed producers and repairers of EPAL load carriers, has launched Euro QR code pallets to boost supply chain visibility, improve efficiency, and optimise stock management.

The SIR is an expanded and rebranded 2.0 version of HIR and reflects the changing realities of the global security printing industry. As holograms are increasingly incorporated with other optically variable devices (OVDs) to provide integrated, added value and advanced anti-counterfeiting solutions, the new SIR will include all optical security technologies falling within the general term of OVD.

The International Hologram Manufacturers Association (IHMA) Excellence in Holography awards recognises those at the forefront of developing innovative or commercially viable holography products or techniques.

Science and technology group Merck and micro-transponder producer p-Chip Corp have formed an alliance to use p-Chip’s technology as a crypto-anchor (unique identifier) for creating digital twins of physical products, allowing them to be tracked and authenticated through the supply chain.

In the February issue of Authentication & Brand News™, we asked whether EU digital product passports (DPPs) could double as anti-counterfeiting devices, in addition to their primary role of gathering information about a product and its supply chain in order to support the transition to a circular economy.

Researchers at the University of Hong Kong have developed a rubber-like colour-changing system called Morphable Concavity Array (MoCA), with the potential to bestow robots with compound vision, similar to an insect.
