A Taiwanese systems integration company has used one of Advantech's 486-based palm-size SBCs to create a fingerprint ID system that can be used in conjunction with door locks, gates or safes, as well as for employee check-in/check-out stations. This fingerprint ID system uses 8 MB of onboard flash memory, which can be expanded if required, to store the fingerprints of up to 300 individuals. The maximum number of finger- prints that can be stored depends on the amount of detail one desires and also influences accuracy as well as processing time.
This information storing and processing is done by a master device, while up to four slave devices can be attached via an RS232 connection. This device can be used for applications in which security and/or automated identity checks are crucial, such as door/gate locks, bank or business safes and workplace employee time management.
Advantech's PCM-4825 486-base palm-size SBC was chosen for several reasons. This tiny board comes with onboard DX5-133 CPU, VGA/LCD and audio, as well as connectors and sockets for SSD, PC/104 modules, and a RS232 serial port. These industrial grade devices can be operated in harsh environments for 24 hours a day. Also, quality, reliability, and local technical support were important factors in this company's decision to choose Advantech. In the future, this company plans to use Advantech's new PCM-5820 Pentium-level palm-size SBC to further increase this device's fingerprint recognition speed.
