ZEM500
is the highest development platform of huge capacity
fingerprint identification. It adopts 32 bit parallel
high-speed CPU with main frequency 400MHZ that can
be integrated with TFT,USB Host, WIFI, GPRS/CDMA
and other external equipments. Its identifying speed
can reach 1000-2000/s based on the 1:many verification
mode.
