School ofElectric and InformationEngineering,HunanUniersity, Changsha 410082, China) Abstract: An network attendence system based on fingerprint recognition technology isdiscussed in this paper. ThisSystem can avoid helping others attending by using fingerprint identification technology and connect the terminaldevicesbased on SingleChipM icrocomputer toEthernet by usingATOP TigerLink G 21S256. The total idea designed for thissystem is described and the mi plantations of hardware and sofwt are ofSCM in thissystem are introduced.
