Abstract
In a fingerprint identification system, a fingerprint sensorof a registration apparatusreads a fingerprint in a larger region, whereas a fingerprint sensorof an identification apparatuswhich is smaller in size, reads a fingerprint in a smaller region. When registering a fingerprint, the fingerprint sensorof the registration apparatusreads a fingerprint, and a fingerprint registration circuitgenerates binary image data based on the fingerprint which has been read. The binary image data is transferred to the identification apparatusand stored in an image memoryof the identification apparatusWhen identifying a fingerprint, the fingerprint sensorof the identification apparatusreads a fingerprint, and a fingerprint identification circuitgenerates binary image data based on the fingerprint which has been read. Then, the binary image data is compared against the binary image data stored in the image memory
