An apparatus for the collection of a chemical sample from the fingers of an individual for subsequent analytical analysis comprises a token having a base and a substrate on the base. The substrate defines an area such that when the token is removed from a token dispenser the fingers of the individual come into contact with the substrate. Sufficient force must be applied by the fingers of the individual to the substrate when the token is removed from the token dispenser that a chemical sample is transferred from the fingers of the individual to the substrate. The token is then presented for analysis. The substrate may be polytetrafluoroethylene or cotton. A token handler for use in association with the token and an analyzer is also disclosed. Additionally, a method of using the token to obtain a chemical sample from the fingers of an individual is disclosed.
