This fake bank note is what Dutch customs officers use to train their sniffer dogs for detecting large quantities of cash.
According to the customs’ Facebook page, where we found this photo, “we’ve been using special training bank notes since 2014. The ink and paper are the same as those of real bank notes, so that the dogs are still able to make a positive match.”
The customs department uses fake money because some of the training sessions are performed in the wild. Using large amounts of real money would be risky in those cases.
