In recent years Vietnam has been a go-to country for many of the world players in the technology, automotive, and fashion industries. It is now stepping into a new field – polymer banknote substrates and security features.

As an anti-forgery expert with the Egyptian Ministry of Justice, I have spent decades investigating the strength and security of various banknote substrates. My work has involved analysis of the technical specifications of banknotes, through extensive mechanical and chemical testing, as well as an assessment of data published by central banks. I’d like to share my findings here.

Spectra Systems has developed its own print-ready machine- readable banknote polymer substrate, FUSION™, working exclusively with Toray Plastics America.

Readers will recall in earlier editions that we addressed a number of significant highlights following G+D`s Currency Technology Symposium held in July. This is the final story, focusing on key elements of the day dedicated to Louisenthal, G+D’s substrate and feature subsidiary.

Earlier this year Giesecke+Devrient outlined a solution for banknote waste which is ‘straightforward, flexible and scalable’ (see CN July 2023). After having introduced the concept of Banknote Fibre Extraction (BFE) at the CT Symposium, the next development phase has taken place.

In this issue, we describe the industry’s newest banknote production facility – IMBISA in Spain. Another example of a new printworks that has also built innovation in from the start is Guangzhou Banknote Printing Co Ltd (GBPC), the seventh and newest of China Banknote Printing and Minting’s banknote factories.
