Honeywell is the world’s leading provider of authentication technologies and solutions, with a long heritage of innovation, performance and reliability.

Our experience in developing trusted authentication management systems dates back more than a century, where we pioneered luminescent pigment development for authentication applications under the Riedel-de-Haën brand. Over the last 40 years, Honeywell has served the world’s leading businesses and monetary institutions by meeting their brand protection, currency & document security needs – using a diverse and unique portfolio of covert luminescent pigments, chemical taggants and optoelectronic detection systems.

Over the last years, Authentication Technologies has invested into digital authentication to protect the Honeywell brand.
