Nrog rau qhov nce ntxiv ntawm cov khoom thauj ntawm tag nrho lub zej zog, qhov kev ua haujlwm cais tawm tau hnyav dua thiab hnyav dua.
Yog li ntawd, ntau thiab ntau lub tuam txhab tab tom qhia cov txheej txheem kev cais tawm digital ntau dua.
Hauv cov txheej txheem no, lub luag haujlwm ntawm RFID thev naus laus zis kuj tseem loj hlob tuaj.

Muaj ntau yam haujlwm hauv kev khaws khoom thiab kev xa khoom. Feem ntau, kev ua haujlwm cais khoom hauv chaw faib khoom yog ib qho tseem ceeb heev
Qhov txuas hnyav thiab ua yuam kev yooj yim. Tom qab kev qhia txog RFID thev naus laus zis, lub kaw lus xaiv digital tuaj yeem tsim los ntawm RFID
kev sib kis wireless, thiab kev ua haujlwm cais tawm tuaj yeem ua tiav sai thiab raug los ntawm kev sib tham sib
kev taw qhia ntawm cov ntaub ntawv ntws.

Tam sim no, muaj ob txoj hauv kev tseem ceeb los paub txog kev txheeb xyuas digital los ntawm RFID: DPS
(Lub Tshuab Xaiv Cov Cim Hluav Taws Xob Uas Tshem Tau) thiab DAS (Lub Tshuab Xaiv Cov Cim Hluav Taws Xob Uas Muaj Noob).
Qhov sib txawv loj tshaj plaws yog tias lawv siv RFID cov cim npe los cim cov khoom sib txawv.

DPS yuav tsum teeb tsa daim ntawv cim RFID rau txhua hom khoom ntawm txhua lub txee hauv thaj chaw ua haujlwm xaiv khoom,
thiab txuas nrog lwm yam khoom siv ntawm lub kaw lus los tsim ib lub network. Lub khoos phis tawj tswj hwm tuaj yeem tshaj tawm
cov lus qhia xa khoom thiab teeb cov cim RFID rau ntawm cov txee raws li qhov chaw ntawm cov khoom
thiab cov ntaub ntawv teev cov xaj. Tus neeg teb xov tooj tuaj yeem ua tiav "daim" lossis "lub thawv" raws sijhawm, raug thiab yooj yim
raws li qhov ntau ntawm cov khoom uas tau tso tawm los ntawm RFID tag Unit cov haujlwm xaiv khoom.

Vim tias DPS npaj txoj kev taug kev ntawm cov neeg khaws khoom thaum lub sijhawm tsim qauv, nws txo qhov tsis tsim nyog
kev taug kev ntawm tus neeg teb xov tooj. Lub kaw lus DPS kuj paub txog kev saib xyuas tiag tiag nrog lub khoos phis tawj, thiab muaj ntau yam
cov haujlwm xws li kev ua tiav kev txiav txim thaum muaj xwm txheej ceev thiab kev ceeb toom thaum tsis muaj khoom.

DAS yog ib lub kaw lus uas siv RFID cov cim npe los paub txog kev cais cov noob tawm ntawm lub tsev rau khoom. Qhov chaw khaws khoom hauv DAS sawv cev rau
txhua tus neeg siv khoom (txhua lub khw, kab tsim khoom, thiab lwm yam), thiab txhua qhov chaw cia khoom muaj cov cim RFID. Tus neeg teb xov tooj ua ntej
nkag mus rau cov ntaub ntawv ntawm cov khoom kom raug txheeb xyuas rau hauv lub system los ntawm kev luam theej duab lub bar code.
Daim ntawv cim RFID uas qhov chaw xaiv cov khoom ntawm tus neeg siv khoom nyob yuav ci thiab nrov nrov, thiab tib lub sijhawm nws yuav tso saib
qhov ntau npaum li cas ntawm cov khoom raug xaiv uas xav tau ntawm qhov chaw ntawd. Cov neeg xaiv khoom tuaj yeem ua cov haujlwm xaiv sai sai raws li cov ntaub ntawv no.

Vim tias lub kaw lus DAS raug tswj hwm raws li tus lej cim ntawm cov khoom lag luam thiab cov khoom seem, cov lej barcode ntawm txhua yam khoom lag luam
yog qhov xwm txheej tseem ceeb rau kev txhawb nqa DAS system. Tau kawg, yog tias tsis muaj barcode, nws kuj tuaj yeem daws tau los ntawm kev nkag mus rau hauv tes.
