Xov xwm

RFID (Radio Frequency Identification), nws lub hauv paus ntsiab lus yog cov ntaub ntawv tsis sib cuag ntawm tus nyeem ntawv thiab lub cim kom ua tiav lub hom phiaj ntawm kev txheeb xyuas lub hom phiaj.Tsuav nws yog ib txoj kev xov tooj cua zaus, thiab tuaj yeem txheeb xyuas qhov no, nws raug suav tias yog qeb RFID.Raws li qhov zaus, nws feem ntau tuaj yeem muab faib ua qhov tsawg zaus, siab zaus, ultra-siab zaus, 2.4G thiab lwm yam.RFID yog siv dav, nrog rau cov ntawv thov xws li kev tswj tsiaj, kev tswj tsheb, kev tsim cov kab ntau lawm, kev tswj cov cuab yeej cuab tam, kev tswj cov neeg ua haujlwm, thiab kev kho mob ntse.

NFC (Nyob ze rau Kev Sib Txuas Lus) thev naus laus zis tau pib ntau dua tom qab RFID.Nws yog ib qho kev sib txuas lus luv luv wireless feem ntau txhawb nqa los ntawm Philips, Nokia thiab Sony nyob ib ncig ntawm 2003. Nws yog txoj kev sib txuas lus luv luv.Kev khiav hauj lwm zaus yog 13.56MHz, thiab kev sib txuas lus yog 106kbit / sec rau 848kbit / sec.Los ntawm lub xov tooj ntawm tes raws li tus neeg nqa khoom, daim ntawv thov tsis sib cuag IC daim npav ua ke nrog lub xov tooj ntawm tes, thiab peb daim ntawv thov hom ntawv, tus nyeem ntawv thiab taw tes rau taw tes yog siv los paub txog kev them nyiaj mobile, daim ntawv thov kev lag luam, kev pauv pauv, daim pib hluav taws xob. , kev lees paub tus kheej, kev tiv thaiv cuav, kev tshaj tawm, thiab lwm yam.

RFID tsuas yog txhais tau tias txuas lub RFID Circuit Court uas muaj RFID xov tooj cua zaus thiab lub kav hlau txais xov voj rau ib yam khoom.Tom qab cov khoom nqa RFID tag nkag mus rau qhov chaw sib nqus tshwj xeeb teeb tsa, nws yuav xa tawm lub teeb liab ntawm qhov tshwj xeeb zaus, thiabRFID nyeem ntawvtuaj yeem tau txais cov ntaub ntawv sau rau ntawm cov khoom ua ntej.Qhov no me ntsis zoo li daim paib dai ntawm caj dab ntawm cov neeg ua haujlwm, thiab koj yog nws tus thawj saib xyuas.Thaum nws nkag rau hauv koj txoj kab pom, koj tuaj yeem paub nws lub npe, txoj haujlwm thiab lwm yam ntaub ntawv, thiab koj tuaj yeem sau cov ntsiab lus ntawm nws daim paib.Yog tias RFID yog tus neeg hnav daim paib kom lwm tus tuaj yeem nkag siab nws, ces NFC yog ob tus neeg hnav cov paib, thiab lawv tuaj yeem hloov cov ntsiab lus ntawm daim paib tom qab pom ib leeg, thiab hloov cov ntaub ntawv tau txais los ntawm lwm tus neeg.NFC thiab RFID zoo ib yam ntawm lub cev, tab sis lawv yog ob qho tib si sib txawv kiag li, vim RFID yog qhov tseem ceeb ntawm kev txheeb xyuas cov cuab yeej, thaum NFC yog kev sib txuas lus thev naus laus zis.Cov kev sib txawv tshwj xeeb yog tshwm sim hauv cov hauv qab no

1. Kev khiav hauj lwm zaus: NFC zaus yog tsau ntawm 13.56MHz, thaum RFID suav nrog active (2.4G, 5.8G), semi-active (125K, 13.56M, 915M, 2.4G, 5.8G), thiab passive RFID.Feem ntau yogpassive RFID, uas tuaj yeem muab faib ua tsawg zaus (125KHz / 134.2KHz), siab zaus (13.56MHz) thiab ultra-high zaus (860-960) zaus bands raws li zaus.

2. Kev ua haujlwm hom: NFC integrates contactless card reader, contactless card thiab peer-to-peer functions rau hauv ib nti, thaum rfid yuav tsum muaj ib tug nyeem ntawv thiab ib tug tag.RFID tsuas tuaj yeem paub txog kev nyeem ntawv thiab kev txiav txim siab ntawm cov ntaub ntawv, thaum NFC thev naus laus zis hais txog kev sib cuam tshuam cov ntaub ntawv.NFC txhawb ob hom nyeem-sau thiab daim npav hom;Hauv RFID, daim npav nyeem ntawv thiab daim npav tsis sib cuag yog ob lub koom haum ywj pheej thiab tsis tuaj yeem hloov pauv.NFC txhawb P2P hom, RFID tsis txhawb P2P hom.

3. Ua haujlwm nrug: Kev ua haujlwm deb ntawm NFC yog qhov kev xav tau 0 ~ 20cm, tab sis nyob rau hauv kev paub txog cov khoom, vim yog siv cov cuab yeej tshwj xeeb hluav taws xob, kev ua haujlwm nrug tsuas yog 0 ~ 10cm, thiaj li ua kom muaj kev ruaj ntseg zoo dua. ntawm kev lag luam;Txij li thaum RFID muaj ntau zaus, nws qhov kev ua haujlwm nyob deb txawv ntawm ob peb centimeters mus rau kaum ntawm meters.

4. Cov txheej txheem txheem: Cov txheej txheem kev sib txuas lus hauv qab ntawm NFC yog sib xws nrog cov qauv kev sib txuas lus hauv qab ntawm high-frequency RFID, uas yog, sib xws nrog ISO14443 / ISO15693 tus qauv.NFC thev naus laus zis kuj txhais cov txheej txheem txheej txheem ua tiav, xws li LLCP, NDEF thiab RTD, thiab lwm yam, thaum RFID raws tu qauv tuaj yeem txhawb ISO 11784 & 11785, ISO14443 / ISO15693, thiab EPC C1 GEN2 / ISO 18000-6C thiab lwm yam raws li cov qauv. txawv zaus.Txawm hais tias NFC thiab RFID thev naus laus zis sib txawv, NFC thev naus laus zis, tshwj xeeb tshaj yog cov thev naus laus zis kev sib txuas lus, tau ua tiav nrog cov cuab yeej siv RFID siab.Yog li ntawd, nyob rau hauv daim ntawv thov teb ntawm high-frequency RFID, NFC technology kuj siv tau.

5. Daim ntawv thov kev taw qhia: RFID yog siv ntau dua hauv cov kab ntau lawm, kev xa khoom thauj khoom, kev tswj cov khoom vaj khoom tsev thiab lwm yam kev siv, thaum NFC ua haujlwm hauv kev tswj kev nkag, npav npav, kev them nyiaj mobile thiab lwm yam.
