romaco has created a system allowing optical verification of medications in blister packaging, which it demonstrated at the recent achema exhibition. the technology takes advantage of highspeed 3d scanning methods which allow coding such as micro barcodes to be read on the surface of products at the micron level. it is also possible for individual pills to be marked with a surface topography code which can be scanned through the packaging and verified against a corresponding code printed onto the blister pack. verification can be a simple and efficient process, requiring only a laser pointer, making implementation of the system relatively straightforward.
