50 Euro bill from a money transportation container after contamination with anti-theft dye
Furthermore, banknotes can be examined which have been contaminated by anti-theft dye. These banknotes originate from criminal offences, such as robberies of banks or cash carrying vehicles or forced openings of cash machines. The purpose of the dyeing is to render the bills "useless". However, these banknotes still circulate or attempts are made to exchange these bills after cleaning them chemically.
