From simple YES / NO detection to the use of complex codes (MultiCode™).
Louisenthal is a provider of innovative magnetic coding systems for security threads which ensure readability of sensor systems co-developed with Giesecke & Devrient. Louisenthal’s magnetic features offer the complete capability of customized thread encoding and machine-based authentication.
Machine-readable electrical conductivity
Persistent electrical conductivity along the thread is a basic machine-readable feature and is possible with most security thread types.
UV fluorescence – authentication with the aid of UV lamp
Various individual colors, color combinations, or rainbow effects become visible under UV light.
Pole® – authentication with the aid of polarization filters
Pole® is an attractive and innovative feature which is suitable for use instead of or in addition to common UV fluorescence. Pole® was awarded the distinction of “Best New Currency Feature” by the International Association of Currency Affairs (IACA) in 2008.
