Detecting fraud

High-speed 3D scanning methods can read microstructured codes on product surfaces.

NANO 4 U and the Romaco machines maker have developed a system for optically verifying blister-pack medicines. The technology is based on high-speed 3D scanning methods that can read micro barcodes on product surfaces. Tablets can be marked individually with a microstructured code that is scanned through the packaging and verified against a code on the pack. Reading can be very simple, for example using a laser pointer, which makes it relatively easy to install the system.

The new technology has been designed not to affect production speeds.

While initially developed for the pharmaceutical industry, subject to strict regulations on protection from counterfeiting, this inexpensive authentication by microstructured code recognition can be applied to any industrial product.
