The Call of the Siren – Hueck Folien's Latest House Note

Hueck Folien unveiled the third in its trilogy of new house notes for 2026 at the Currency+Identity conference in Copenhagen.

The programme began in April 2026 with the launch of the 'Vault Bill' house note at the Global Currency Forum. Developed in cooperation with IQ Structures and Landqart, the project served as a platform for presenting new optical-security concepts to the currency community.

Breath Note.

The company then unveiled the 'Breath' house note at HSP Latin America in Guatemala in June. Developed with Poland's PWPW, the environmentally themed design depicts a pair of lungs formed from trees. It incorporates an Optomove® security thread featuring a customised Falling Leaves effect. Based on ColorSwitch™ technology, the thread shifts from green to gold while creating a dynamic movement effect. It also incorporates the first Hueck Folien Nanoswitch® stripe combined with colourful TRILUMIC® UV printing, demonstrating how multiple optical technologies can be integrated within a single banknote design (see CN July 2026).
