-2-I Introduction
OperationPrinciple
Fingerprintprocessingincludestwoparts:fingerprintenrollmentandfingerprintmatching(the
matchingcanbe1:1or1:N).
Whenenrolling,userneedstoenterthefingertwotimes.Thesystemwillprocessthetwotime
fingerimages,generateatemplateofthefingerbasedonprocessingresultsandstorethetemplate.
Whenmatching,userentersthefingerthroughopticalsensorandsystemwillgenerateatemplateofthe
fingerandcompareitwithtemplatesofthefingerlibrary.For1:1matching,systemwillcomparethe
livefingerwithspecifictemplatedesignatedintheModule;for1:Nmatching,orsearching,systemwill
searchthewholefingerlibraryforthematchingfinger.Inbothcircumstances,systemwillreturnthe
matchingresult,successorfailure.

WhethertheinterfaceisUARTor USB(hardwaresettingisdifferentwhenoutoffactory,pleasedon't
misuse),onPCBboardtheconnectorisuniform.Forsplittype,5-pinconnector(J1)with 2.0mm space
between;forintegraltype, 4-pinconnector(J1)with1.27mmspacebetween.
Unlessrequiredspeciallybyuser,theconnectingcablewith uppercomputeris 150mm.
