Fingerprint scanner
Most of the sensors described have been altered in the past. To avoid this, a new operating mode has been added. Instead of simply placing your finger statically on the sensor, the finger moves slowly along it. The sensor only has a narrow sensitive area, and generates a complete sequence of images, which can be reassembled, by means of a processor, in a complete image. The benefits are improved appreciably and the elimination of any residual grease is guaranteed.
