The former Giesecke & Devrient Banknote business unit debuted as the Giesecke & Devrient Currency Technology independent subgroup at this year’s Currency Conference, May 15-18 in Kuala Lumpur, according to a press release.

Giesecke & Devrient Currency Technology demonstrated two new security features: the 3-D Galaxy high-security thread; and the varifeye ColourChange foil window. Both are complex, high-tech products that rely on intuitive perception, the release said.

A combination of micromirror and ColourShift technologies enables optically variable effects that can be integrated into or applied onto the substrate.

Even inexperienced observers are able to perceive the dynamic color shifts and movement effects apparent when the banknote is turned, no matter how poor the lighting, according to G&D.

Dr. Wolfram Seidemann, chairman of the currency technology management board, described the features as “beautifully bringing together outstanding security with exceptional aesthetics. Keeping cash both secure and attractive in equal measure has resulted in it continuing to be an integral part of modern life. Banknotes are, by a distance, the most secure payment method worldwide.”

In its most recent study of bank note security, the European Central Bank found that the probability of physically holding a counterfeit banknote is around 0.00019 percent, the release said.

“Stable currency systems need cash just as much as they need digital or mobile payment methods,” Dr. Seidmann said. “This means we also need to take advantage of the opportunities offered by Industry 4.0 and digitization to make the cash cycle increasingly efficient.”
