A prototype fingerprint scanner has been developed that can detect the presence of opiates, cannabis, or cocaine in the sweat on a user's fingertip.
The device uses special cartridges to take a fingerprint, which are then processed using both chemical testing and a unique photo scanning system. This takes a high resolution image of the fingerprint and its residue, so that the output from individual sweat pores can be measured.
If the device takes off, it will make travelling in certain locales quite risky, since some countries – notably Dubai – have such strict anti-drug laws that even having drugs in your bloodstream counts as importation.
