This volume presents the proceedings of Optical & Digital Document Security™ (ODDS) Conference 2025, held in Warsaw, Poland, on 16 – 17 September. Organised by Reconnaissance International with the guidance of the ODDS Technical Committee, the conference reaffirmed ODDS as the definitive forum for physical, digital, and hybrid document security.

The ‘Smartphones for Authentication’ report summarises the wide range of technologies underpinning the role of smartphones in the authentication arena, with the aim of identifying further opportunities… as well as potential drawbacks.

This report is now available to purchase

A new technology report exploring the domain of commercial printing innovations that go beyond visual colour, with the potential to generate entirely novel features for secure documents.
This 60-page report targets security printers and authentication solution providers for the currency, ID, tax stamp and brand protection sectors. It offers informative technical analyses of latest generation inks and digital printing techniques and how these could be adapted and applied to the security world.

An essential guide to the technology behind security threads for banknotes

More than 75 years ago the first use of a security thread for a banknote appeared. Since then they have evolved to become one of the most enduring and innovative features on banknotes.

The special report examines the evolution of security for banknotes, their types, latest technology developments (including optically variable effect windowed threads based on micromirror, lenticular, diffractive and colour shift technologies), material science machinereadability, design integration, incorporation and future developments.

Whether you supply or use security threads, or the materials and technology that make them so effective, this is your chance to reach those organisations that are looking for your products services and solutions.

The definitive source of data and analysis on the market worldwide for tax stamp and excise recovery programmes.
This is the only report of its kind to examine and analyse the global tax stamp and traceability market for alcohol, tobacco and other products subject to excise. It provides invaluable insight into how governments can develop effective tax revenue collection and anti-illicit trade regimes that comply with the latest international regulations through the use of tax stamp and track and trace programmes, as well as how suppliers of physical and digital tax stamp solutions can both help drive forward the market, and benefit from the growing opportunities these provide.

There is a revolution underway in the secured document field, as society migrates from using physical secured documents, such as banknotes and identity cards, to the use of smartphones and electronic payment cards for financial transactions and as carriers of our identity credentials.
There is a perception that this revolution is well underway and that the transition from physical to digital is inevitable, unstoppable and irrevocable. The drivers are user convenience and provider cost savings, allied to the technical community’s belief that it can deliver a new way of doing things. Perception trumps reality for now, though, as cash is still used for most retail purchases globally and passports are still required to enter a territory. Nonetheless, this transition is inevitable, so there is a need to consider the impact and implications of this change.

An In-Depth Report on the Evolution of Diffractive Features on Banknotes Over the Past 30 Years

2017 marked the 70th anniversary of the invention of the hologram, while 2018 is the 30th anniversary of the first use of a diffractive feature (optically variable device or OVD) on a banknote. Since then, it has evolved to become one of the most enduring and successful public security features for currency.

To mark these milestones, Currency News has published ‘Diffractive Features on Banknotes, a special report examining the evolution of diffractive OVDs on currency; the latest developments in origination, materials science and application; best examples of design integration and the re-engineering of the technology for the latest generation of substrates and window features.
