摘要： A fingerprint and token sensor system includes an array of fingerprint sensing elements for generating signals related to a fingerprint based upon a finger being positioned adjacent the sensing elements, and a token for also causing the sensing elements to generate signals related to a token message based upon the token being positioned adjacent the sensing elements. Accordingly, the single sensor may be used for both fingerprints and for reading data from a token for range of useful purposes. Each fingerprint sensing element may preferably include an electric field sensing electrode, and a shield associated with a respective electric field sensing electrode. A drive circuit may be connected to the array of electric field sensing electrodes for driving same. The sensor is preferably in the form of an integrated circuit and includes a substrate adjacent the array of fingerprint sensing elements. The token may include an array of electrically conductive elements, a pattern defined by different dielectric values, or electric field generating elements cooperating with the array of electric field sensing electrodes. The elements may be carried on a card, for example. The data message of the token may include further information related to the identity of the token bearer, for example, or may confirm the proper identity of the bearer based upon a match with the live fingerprint of the bearer. Alternately, the token could bypass the requirement for a live fingerprint.
