Introduction
Intermsofstructure,RFIDisasimplewirelesssystemwithonlytwobasiccomponents.Thesystemisusedtocontrol,detectandtrackobjects.Thesystemconsistsofaninterrogator(orreader)andmanytransponders(ortags).
Atfirstinthetechnicalfield,thetransponderreferstoanelectronicmodulethatcantransmitinformationandreplyinformation.Inrecentyears,duetotherapiddevelopmentofradiofrequencytechnology,thetransponderhasanewmeaningandmeaning,andisalsocalledasmartlabel.Orlabel.TheRFIDelectronictagreader(reader)communicateswirelesslywiththeRFIDelectronictagthroughanantenna,whichcanreadorwritethetagidentificationcodeandmemorydata.Atypicalreaderincludesahigh-frequencymodule(transmitterandreceiver),controlunitandreaderantenna.RFIDradiofrequencyidentificationisanon-contactautomaticidentificationtechnology,whichautomaticallyrecognizesthetargetobjectandobtainsrelevantdatathroughradiofrequencysignals.Theidentificationworkdoesnotrequiremanualinterventionandcanworkinvariousharshenvironments.RFIDtechnologycanidentifyhigh-speedmovingobjectsandcanidentifymultipletagsatthesametime,andtheoperationisquickandconvenient.
Inthefuture,theChinaInternetofThingsSchool-EnterpriseAlliancebelievesthattherapiddevelopmentofRFIDtechnologyisofgreatsignificancetotheprogressoftheInternetofThingsfield.

(1)Featuresofradiofrequencytechnology
Themostimportantadvantageofradiofrequencyidentificationsystemisnon-contactidentification,whichcanpenetratesnow,fog,ice,Labelscanbereadinharshenvironmentswherepaint,dirt,andbarcodescannotbeused,andthereadingspeedisextremelyfast,inmostcaseslessthan100milliseconds.Theshorthandabilityofactiveradiofrequencyidentificationsystemsisalsoanimportantadvantage.Itcanbeusedforinteractiveservicessuchasprocesstrackingandmaintenancetracking.
Themainproblemrestrictingthedevelopmentofradiofrequencyidentificationsystemsisincompatiblestandards.Themajormanufacturersofradiofrequencyidentificationsystemsprovidededicatedsystems,leadingtodifferentapplicationsanddifferentindustriesadoptingdifferentmanufacturer'sfrequencyandprotocolstandards.Thischaoticandsegregatedsituationhasrestrictedthegrowthoftheentireradiofrequencyidentificationindustry.ManyEuropeanandAmericanorganizationsareworkingtosolvethisproblemandhaveachievedsomeresults.Standardizationwillcertainlystimulatethesubstantialdevelopmentandwideapplicationofradiofrequencyidentificationtechnology.
(2)Theapplicabilityofradiofrequencytechnologyinlogisticsmanagement.Theessenceoflogisticsmanagementistoreducecostsandimproveservicelevelsthroughthemanagementoftheentirelogisticsprocess.Howtoensurethattherightcustomersgettherightproductsattherighttimeandattherightplacewiththerightcostandtherightconditionshasbecomethehighestgoalpursuedbylogisticsenterprises.Forthisreason,masteringthequantity,formanddistributionofinventoryandimprovingtheliquidityofinventoryhavebecomethecorecontentoflogisticsmanagement.Generallyspeaking,thevalueofacompany’sinventoryaccountsforabout25%ofthecompany’stotalassetsandmorethan50%ofthecompany’scurrentassets.Therefore,thecoreoflogisticsmanagementisthemanagementofinventoryinthesupplychain.
Usingradiofrequencyidentificationtechnologyintransportationmanagement,itonlyneedstoinstallelectronictagsontheouterpackagingofthegoods,andsetupreadersatthetransportationcheckpointortransferstationtorealizethevisualmanagementofassets.Duringtransportation,thereadertransmitstheinformationoftheelectronictagtothedatabaseofthetransportationdepartmentviasatelliteortelephoneline.Eachtimetheelectronictagpassesthroughacheckpoint,thedatainthedatabaseisupdated.Whentheelectronictagreachesthedestination,thedatabaseisclosed.Atthesametime,cargoownerscanaccessvisualizedwebpagesintransitaccordingtotheirpermissionstounderstandthespecificlocationofthecargo,whichisofgreatsignificancetoimprovingtheserviceleveloflogisticsenterprises.

AcompleteRFIDsystemiscomposedofthreeparts:Reader,TAG,so-calledTransponder,andapplicationsoftwaresystem.ItsworkingprincipleItistheReaderthattransmitsaspecificfrequencyofradiowaveenergytotheTranspondertodrivetheTranspondercircuittosendouttheinternaldata.Atthistime,theReaderreceivesandinterpretsthedatainsequenceandsendsittotheapplicationforcorrespondingprocessing.
FromtheperspectiveofcommunicationandenergysensingmethodsbetweenRFIDcardreadersandelectronictags,itcanberoughlydividedintotwotypes:inductivecouplingandbackscattercoupling.Generally,low-frequencyRFIDmostlyadoptsthefirstmethod,whilehigher-frequencyRFIDmostlyadoptsthesecondmethod.
Thereadercanbeareadorread/writedevicedependingonthestructureandtechnologyused,anditistheRFIDsysteminformationcontrolandprocessingcenter.Thereaderusuallyconsistsofacouplingmodule,atransceivermodule,acontrolmoduleandaninterfaceunit.Thereaderandthetranspondergenerallyusehalf-duplexcommunicationforinformationexchange,andthereaderprovidesenergyandtimingtothepassivetransponderthroughcoupling.Inpracticalapplications,managementfunctionssuchasthecollection,processingandremotetransmissionofobjectidentificationinformationcanbefurtherrealizedthroughEthernetorWLAN.ThetransponderistheinformationcarrieroftheRFIDsystem.Mostofthetransponderisapassiveunitcomposedofacouplingelement(coil,microstripantenna,etc.)andamicrochip.
