MBF200 Solid State Fingerprint Sensor fact sheet - 1

Description The Fujitsu MBF200 solid-state Fingerprint Sensor (see diagram on following page) is a rugged, super thin, silicon-based, direct contact, fingerprint acquisition device. Fingerprint authentication providesa reliable, quick, and user-friendly alternative to password inefficiency which requires the user to recall and enter cumbersome and often numerous code combinations. One advantage of the MBF200 fingerprint sensor is its ease of integration into portable electronic systems such as laptops, personal digital assistants (PDAs), and cellular phones. Other advantages include: durable construction, high performance, exceptional image clarity, small size, low power consumption, and lowerunit cost than optical scanners.The MBF200 sensor consists of a256 x 300 column and row configuration of tiny metal electrodes. Every column is linked to a pair of sample-and-hold circuits. The fingerprint image is recorded in sequence row by row. Each metal electrode acts as one capacitor plate and the contacting finger acts as the second plate. A passivation layer on the surface of the device forms the dielectric between these two plates. A finger-press on the sensor creates varying capacitor values across the array which are then converted into an image of the fingerprint. The values of the array are determined by the contour (ridges and valleys) of the fingerprint. In under one second, thesensor quickly captures several images of the fingerprint and selects the highest quality image. Skin moisture (damp or dry) is accounted for, thus making the sensor ideal in a wide range of climates. Once the fingerprint has been scanned, it is verified against the stored template of the individuals fingerprint.The MBF200 is manufactured instandard CMOS technology. The 256 x 300 sensor array yields a clear, high quality 500dpi image. An integrated 8 bit analogue-to-digital converter is used to digitise the output of the sensor array.Each MBF200 chip supports threedifferent industry-standard bus >
