Nrog rau kev txhim kho kev lag luam hauv tebchaws thiab qhib kev lag luam, kev lag luam dav hlau hauv tebchaws tau ua tiav kev loj hlob tsis tau muaj dua, tus naj npawb ntawm cov neeg caij tsheb nkag thiab tawm hauv tshav dav hlau tau txuas ntxiv nce ntxiv, thiab cov khoom thauj tau mus txog qhov siab tshiab.

Kev tswj cov hnab nqa khoom yeej ib txwm yog ib txoj haujlwm loj thiab nyuaj rau cov tshav dav hlau loj, tshwj xeeb tshaj yog kev tawm tsam tsis tu ncua rau kev lag luam dav hlau kuj tau tso tawm cov kev xav tau siab dua rau kev txheeb xyuas cov hnab nqa khoom thiab kev siv tshuab taug qab. Yuav ua li cas tswj cov khoom siv thiab txhim kho kev ua haujlwm kom zoo yog qhov teeb meem tseem ceeb uas cov dav hlau ntsib.

Hauv lub tshav dav hlau thaum ntxov tswj hwm lub hnab nqa khoom, cov hnab nqa khoom ntawm cov neeg caij tsheb tau txheeb xyuas los ntawm cov ntawv lo barcode, thiab thaum lub sijhawm thauj khoom, kev cais thiab ua cov hnab nqa khoom ntawm cov neeg caij tsheb tau ua tiav los ntawm kev txheeb xyuas cov barcode. Lub kaw lus taug qab cov hnab nqa khoom ntawm cov dav hlau thoob ntiaj teb tau tsim kho mus txog rau tam sim no thiab tseem laus dua. Txawm li cas los xij, thaum muaj qhov sib txawv loj ntawm cov hnab nqa khoom kuaj xyuas, tus nqi lees paub ntawm cov barcodes nyuaj rau tshaj 98%, uas txhais tau tias cov dav hlau yuav tsum tau nqis peev ntau lub sijhawm thiab kev siv zog los ua haujlwm tes kom xa cov hnab nqa khoom mus rau ntau lub dav hlau sib txawv.

Tib lub sijhawm, vim yog qhov yuav tsum tau ua kom pom tseeb ntawm kev ntsuas barcode, qhov no kuj ua rau cov neeg ua haujlwm hauv tshav dav hlau ua haujlwm ntau ntxiv thaum ua cov ntim khoom barcode. Tsuas yog siv cov barcodes los phim thiab cais cov khoom yog ib txoj haujlwm uas xav tau ntau lub sijhawm thiab lub zog, thiab tej zaum yuav ua rau lub dav hlau qeeb heev. Txhim kho qib kev ua haujlwm tsis siv neeg thiab kev txheeb xyuas qhov tseeb ntawm lub tshav dav hlau lub tshuab cais cov khoom tsis siv neeg yog qhov tseem ceeb heev rau kev tiv thaiv kev nyab xeeb ntawm kev mus ncig pej xeem, txo qhov kev ua haujlwm ntawm cov neeg ua haujlwm hauv tshav dav hlau, thiab txhim kho kev ua haujlwm zoo ntawm tshav dav hlau.

Feem ntau, UHF RFID thev naus laus zis yog ib qho ntawm cov thev naus laus zis muaj peev xwm tshaj plaws hauv xyoo pua 21st. Nws yog ib qho thev naus laus zis tshiab uas tau ua rau muaj kev hloov pauv hauv kev txheeb xyuas tus kheej tom qab thev naus laus zis bar code. Nws muaj qhov tsis pom kev, deb, qhov yuav tsum tau ua kom tsawg, muaj peev xwm sib txuas lus wireless sai thiab raug, thiab nws tau tsom mus rau lub tshav dav hlau lub hnab nqa khoom tsis siv neeg.

Thaum kawg, thaum Lub Kaum Hli Ntuj xyoo 2005, IATA (International Air Transport Association) tau pom zoo ua ke los ua kom UHF (Ultra High Frequency) RFID strap-on tags yog tib tus qauv rau cov paib nqa khoom hauv huab cua. Yuav kom daws tau cov teeb meem tshiab uas cov neeg caij tsheb nqa khoom ua rau lub peev xwm ntawm lub tshav dav hlau thauj khoom, cov khoom siv UHF RFID tau siv rau hauv lub hnab nqa khoom los ntawm ntau lub tshav dav hlau.

Lub tshuab UHF RFID hnab nqa khoom tsis siv neeg yog los lo rau daim ntawv lo hluav taws xob rau ntawm txhua tus neeg caij tsheb lub hnab nqa khoom uas raug kuaj xyuas yam tsis tau npaj tseg, thiab daim ntawv lo hluav taws xob sau cov ntaub ntawv tus kheej ntawm tus neeg caij tsheb, chaw nres nkoj tawm mus, chaw nres nkoj tuaj txog, tus lej dav hlau, chaw nres tsheb, lub sijhawm tawm mus thiab lwm yam ntaub ntawv; cov khoom siv nyeem thiab sau daim ntawv lo hluav taws xob rau ntawm txhua qhov chaw tswj hwm ntawm cov dej ntws, xws li kev cais, kev teeb tsa, thiab kev thov hnab nqa khoom. Thaum cov hnab nqa khoom nrog cov ntaub ntawv cim hla dhau txhua qhov chaw, tus nyeem ntawv yuav nyeem cov ntaub ntawv thiab xa mus rau lub ntaub ntawv kom paub txog kev sib qhia thiab saib xyuas cov ntaub ntawv hauv tag nrho cov txheej txheem ntawm kev thauj khoom.
