ABSTRACT:
A method of identifying a check signer comprises the application of a fingerprint of a person to an identification card in invisible ink. The same fingerprint of the person is applied to the check in invisible ink in the presence of a person requested to cash the check. The fingerprint of the identification card is scanned to provide a first set of electrical signals. The fingerprint of the check is scanned to provide a second set of electrical signals. The first and second sets of electrical signals are compared. Comparison or non-comparison of the first and second sets of electrical signals is indicated to indicate the authenticity of the signer.
