A first capacitor obtains a gate-source voltage of a first transistor in accordance with a programming current flowing through the first transistor, and a second capacitor obtains a threshold voltage of a second transistor. In particular, the systems and methods are for the detection of residues of Chemical or Biological Warfare Agents which may be present within the mail pieces. Each unique symbol in the corpus has an associated key on the keyboard. The form for each institution is created from a form description file.
