A fingerprint sensing system configured for incorporation into a device, the fingerprint sensing system comprising: a fingerprint sensor array comprising a plurality of substantially parallel drive lines (106, 206, 306, 406, 506, 606, 706, 806, 906) located on one surface of an insulating dielectric layer (104, 204, 304, 404, 504, 604, 704, 804) configured to transmit an electric field signal to a finger placed on a surface of the fingerprint sensor array, and a plurality of substantially parallel pickup lines (102, 202, 302, 402, 502, 602, 702, 802, 902) located on an opposite surface of the insulating dielectric layer and oriented substantially perpendicular to the drive lines and separated from the drive lines by the insulating dielectric layer to form intrinsic electrode pairs that are impedance sensitive at each drive and pickup crossover location with a separation between the drive lines and the pickup lines that allows the drive lines to transmit the electric field signal and allows the pickup lines to receive an electric field signal, wherein the transmitted electric field signal is partially captured by the finger and partially captured by the pickup lines; a processor (1030, 1130) configured to process the captured signal from the pickup lines to define a fingerprint image; and a switch (1812/1813, 1912/1913, 2000, 2100) underlying the fingerprint sensor array or embedded within layers of the fingerprint sensor array to allow a finger of a user to contact the fingerprint sensor array and to actuate the switch simultaneously while contacting the fingerprint sensor array and to allow an integration of fingerprint sensor operations based on the fingerprint image with at least one other operation of the device. a fingerprint sensor array comprising a plurality of substantially parallel drive lines (106, 206, 306, 406, 506, 606, 706, 806, 906) located on one surface of an insulating dielectric layer (104, 204, 304, 404, 504, 604, 704, 804) configured to transmit an electric field signal to a finger placed on a surface of the fingerprint sensor array, and a plurality of substantially parallel pickup lines (102, 202, 302, 402, 502, 602, 702, 802, 902) located on an opposite surface of the insulating dielectric layer and oriented substantially perpendicular to the drive lines and separated from the drive lines by the insulating dielectric layer to form intrinsic electrode pairs that are impedance sensitive at each drive and pickup crossover location with a separation between the drive lines and the pickup lines that allows the drive lines to transmit the electric field signal and allows the pickup lines to receive an electric field signal, wherein the transmitted electric field signal is partially captured by the finger and partially captured by the pickup lines; a processor (1030, 1130) configured to process the captured signal from the pickup lines to define a fingerprint image; and a switch (1812/1813, 1912/1913, 2000, 2100) underlying the fingerprint sensor array or embedded within layers of the fingerprint sensor array to allow a finger of a user to contact the fingerprint sensor array and to actuate the switch simultaneously while contacting the fingerprint sensor array and to allow an integration of fingerprint sensor operations based on the fingerprint image with at least one other operation of the device.
