Parcels, fully wrapped up with adhesive tapes, are common exhibits for forensic laboratories to be analyzed. The simple reason: smugglers try to well package their illegal goods, for example to fool a drug sniffer dog. A piece of adhesive tape, especially its sticky side, can be crucial evidence to identify a drug dealer. Because latent prints on the sticky side of a tape cannot be removed or smudged they can immediately lead to the person who has packaged the narcotics.

To support forensics, EVISCAN provides a reliable method that is suitable to examine both, latent prints on the sticky and non-sticky side of adhesive tapes. Even duct tape can be processed with EVISCAN, despite its wavy surface and regardless of whether it is black or silvery gray.
Results immediately can be saved as digital images and do not need to be photographed in a separate work step. Moreover, EVISCAN eliminates the need of additives such as sticky-side powder and chemical solutions to secure latent print evidence.
