RFID thiab bar codes yog ob qho tib si cov ntaub ntawv nqa cov thev naus laus zis uas khaws cov ntaub ntawv khoom ntawm cov cim npe, tab sis lawv muaj ntau yam haujlwm.Yog li cas koj paub qhov txawv thiab xaiv ntawm ob daim ntawv lo thiab scanning li cas?
Ua ntej tshaj, qhov txawv ntawm RFID thiab bar code yog dab tsi?
1. Cov haujlwm sib txawv
Bar code yog lub tshuab nyeem tau cov lej, qhov dav ntawm ntau cov kab dub thiab qhov chaw dawb, raws li qee qhov kev cai coding, siv los nthuav qhia ib pawg ntawm cov ntaub ntawv graphic identifier.Ib qho bar code feem ntau yog ib qho qauv ntawm cov kab sib txuas ua ke los ntawm cov kab dub (xws li cov tuav) thiab cov kab dawb (xa mus rau qhov khoob) nrog qhov sib txawv heev.Thaum tus nyeem ntawv bar code, lub xov tooj smartphone lossis txawm tias lub tshuab luam ntawv duab luam theej duab bar code, nws tuaj yeem txheeb xyuas cov ntaub ntawv hais txog cov khoom.Cov barcodes tuaj yeem tuaj yeem nyob hauv txhua daim duab thiab qhov ntau thiab tsawg, thiab cov ntsiab lus lawv txheeb xyuas tsis cuam tshuam los ntawm cov duab thiab qhov loj ntawm bar code.
RFID yog cov ntaub ntawv tsis sib txuas lus ntawm tus nyeem ntawv thiab cov cim kom ua tiav lub hom phiaj ntawm kev txheeb xyuas lub xov tooj cua zaus.Xov tooj cua Frequency Identification (RFID) tag muaj microchips thiab xov tooj cua kav hlau txais xov uas khaws cov ntaub ntawv tshwj xeeb thiab xa mus rau RFID nyeem ntawv.Lawv siv electromagnetic teb los txheeb xyuas thiab taug qab cov khoom.RFID cim npe tuaj nyob rau hauv ob daim ntawv, nquag thiab passive.Active tags muaj lawv tus kheej lub hwj chim mov xa lawv cov ntaub ntawv.Sib txawv ntawm passive tags, passive tags xav tau cov neeg nyeem nyob ze kom emit electromagnetic nthwv dej thiab tau txais lub zog ntawm electromagnetic nthwv dej kom qhib cov ntawv cim passive, thiab tom qab ntawd cov ntawv cim passive tuaj yeem hloov cov ntaub ntawv khaws cia rau tus nyeem ntawv.
2. Cov ntawv thov sib txawv
RFID muaj ntau yam kev siv.Tam sim no, cov ntawv thov raug suav nrog tsiaj nti, tsheb nti burglar tswb, kev nkag mus, kev tswj chaw nres tsheb, cov kab ntau lawm automation, tswj cov khoom siv, cim cov khoom, thiab lwm yam Barcodes tuaj yeem kos lub teb chaws ntawm kev tsim khoom, cov chaw tsim khoom, lub npe ntawm cov khoom, hnub ntawm kev tsim khoom, phau ntawv faib tus lej, pib thiab xaus qhov chaw xa ntawv, qeb, hnub tim thiab ntau yam ntaub ntawv, yog li lawv tau siv dav hauv ntau qhov chaw, xws li cov khoom lag luam, kev tswj hwm tsev qiv ntawv, kev tswj xyuas kev lag luam, kev lag luam. system thiab lwm yam.
3. Lub hauv paus ntsiab lus ua haujlwm txawv
Xov tooj cua zaus identification technology los ntawm xov tooj cua tsis hu xov tooj ceev ceev sib pauv thiab cia technology, los ntawm kev sib txuas lus wireless ua ke nrog cov ntaub ntawv nkag mus rau hauv technology, thiab ces txuas mus rau lub database system, ua kom tiav tsis-hu rau ob txoj kev sib txuas lus, thiaj li mus cuag lub hom phiaj. ntawm kev txheeb xyuas, siv rau kev sib pauv cov ntaub ntawv, sib sau ua ke ib qho kev nyuaj heev.Hauv kev lees paub, kev nyeem ntawv, kev sau ntawv thiab kev sib txuas lus ntawm hluav taws xob tag tau pom los ntawm electromagnetic yoj.
Barcode thev naus laus zis tau yug los nrog kev txhim kho thiab siv computer thiab cov ntaub ntawv thev naus laus zis.Nws yog ib tug tshiab technology uas integrates coding, luam ntawv, kev txheeb xyuas, cov ntaub ntawv nrhiav thiab ua.
Nyob rau hauv lub neej tiag tiag, peb tuaj yeem pom cov cim bar code thiab RFID cim npe hauv ntau hom ntim khoom sib txawv, xws li cov khw muag khoom loj, cov khw muag khoom yooj yim, cov khoom siv txhua hnub kom pom cov cim bar code ntau dua, hauv cov khaub ncaws khau thiab hnab thiab lwm yam khoom xws li ntau RFID cim npe. , yog vim li cas qhov no tshwm sim?Cia peb nkag siab txog qhov zoo thiab qhov tsis zoo ntawm cov lej bar code thiab RFID cim npe thiab nyeem thiab sau ntawv.
Qhov zoo thiab qhov tsis zoo ntawm bar Codes
Qhov zoo:
1. Barcodes yog universal thiab siv tau yooj yim, vim cov khw muag khoom nrog cov neeg nyeem ntawv barcode tuaj yeem tuav barcodes los ntawm lwm qhov chaw.
2. Cov ntawv cim bar code thiab cov ntawv nyeem bar code yog pheej yig dua RFID cim npe thiab nyeem ntawv.
3. Cov cim npe bar code yog me thiab sib zog dua RFID cim npe.
Qhov tsis zoo:
1. Barcode nyeem ntawv muaj qhov luv luv ntawm qhov deb thiab yuav tsum nyob ze rau tag.
2. Barcode yog ntau daim ntawv lo yog ncaj qha mus rau huab cua, yooj yim rau hnav thiab tsim kua muag, yooj yim rau kev puas tsuaj los ntawm dej thiab lwm yam kua, tom qab qhov kev puas tsuaj ntawm barcode muaj nuj nqi yuav tsis zoo.
3. Cov ntawv sau cia cov ntaub ntawv tsawg dua.
4. Tus nyeem ntawv bar code yuav tsum tau luam ib tus zuj zus thiab tsis txhawb pab pawg nyeem ntawv, uas ua rau kev nyeem ntawv tsawg.
5. Daim ntawv lo yog ib qho yooj yim rau forged, thiab tus nqi forging yog tsawg.
Qhov zoo thiab qhov tsis zoo ntawm RFID
Qhov zoo:
1.RFID tag thiab nyeem ntawv nyeem nyob deb.
2. Ntau lub cim tuaj yeem nyeem ib zaug, cov ntaub ntawv nyeem ceev.
3. Cov ntaub ntawv siab ruaj ntseg, encryption, hloov tshiab.
4.RFID tag tuaj yeem ua kom muaj tseeb ntawm cov khoom lag luam thiab muaj kev ua haujlwm ntawm kev tiv thaiv cuav thiab traceability.
5.RFID cov cim npe hluav taws xob feem ntau yuav tsum muaj cov yam ntxwv ntawm cov dej tsis sib haum, antimagnetic, kub tsis kam, kom muaj kev ruaj ntseg ntawm daim ntawv thov ntawm xov tooj cua zaus txheeb xyuas tshuab.
6.RFID thev naus laus zis raws li lub khoos phis tawj thiab lwm cov ntaub ntawv khaws cia, txog li ob peb megabytes, tuaj yeem khaws cov ntaub ntawv ntau, kom ntseeg tau tias kev ua haujlwm du.
Qhov tsis zoo:
1. Tus nqi ntawm RFID tag thiab nyeem ntawv yog siab dua qhov bar code.
2. RFID cov cim npe thiab cov neeg nyeem yuav tsum tau xaiv raws li kev nyeem ntawv zaus, qhov deb thiab ib puag ncig, thiab xav tau ntau dua RFID kev paub thiab kev txawj ntse los xyuas kom meej tias qhov kev nyeem ntawv yuav tsum tau ua tiav.
Nws tuaj yeem pom los ntawm cov saum toj no tias cov yam ntxwv ntawm kev ua haujlwm ntawm barcode, RFID tag thiab txhawb kev nyeem ntawv thiab sau cov khoom sib txawv, yog li cov neeg siv khoom yuav tsum xaiv cov khoom tsim nyog raws li kev siv tiag tiag.
