Tsis yog,ICthiabNFCtsis yog tib yam, txawm hais tias lawv muaj kev sib raug zoo heev. Txhawm rau muab nws yooj yim:IC yog "lub hlwb" (qhov kho vajtse), thaum NFC yog ib txoj hauv kev uas lub hlwb "hais lus" wirelessly.
1. IC yog dab tsi? (Lub Hardware)
ICsawv rauIntegrated Circuit Court. Nws yog qhov tseeb silicon nti embedded hauv ib daim npav, xov tooj, lossis daim ntawv cim npe.
Nws yog "lub hlwb" uas khaws thiab ua cov ntaub ntawv.
Koj tuaj yeem pom ICs hauv credit cards (lub me me kub square), SIM cards, thiab txawm tias koj lub computer.
Ib qho IC tuaj yeem yogtiv tauj -raws li(koj yuav tsum ntsaws rau hauv, zoo li daim npav ATM) lossiscontactless(nws muaj lub kav hlau txais xov).
2. NFC yog dab tsi? (Lwm yam/Standard)
NFCsawv rauNyob ze Field Communication. Nws yog cov txheej txheem tshwj xeeb (ib txoj cai) rau yuav ua li cas ob lub cuab yeej tham nrog ib leeg wirelessly nyob deb heev (feem ntau tsawg dua 4 cm).
NFC ib txwm ua haujlwm ntawm ib lub sijhawm tshwj xeeb:13.56 MHz.
NFC yog qhov tseebsubset ntawm RFID(Kev txheeb xyuas xov tooj cua zaus).
Txhawm rau NFC ua haujlwm, lub cuab yeej yuav tsum muajIC ntitxuas nrog ibkav hlau txais xov.
3. Qhov txawv tseem ceeb ntawm ib saib
| Feature | IC (Integrated Circuit Court) | NFC (Nyob ze rau kev sib txuas lus) |
| Nws yog dab tsi? | Lub cev hardware nti. | Tus qauv kev sib txuas lus wireless. |
| Form Factor | Yuav ua tau ib tug pom nti los yog muab zais rau hauv. | Lub teeb liab wireless (invisible). |
| Kev sib txuas | Yuav tiv tauj (plug-in) lossis wireless. | nruj me ntsis wirelessthiab luv - range. |
| Muaj nuj nqi | Khaws cov ntaub ntawv, khiav encryption. | Xa cov ntaub ntawv ntawm cov khoom siv. |
4. Lawv ua haujlwm ua ke li cas (Qhov "Smart Card" Piv txwv)
Xav txog daim npav pej xeem niaj hnub no (xws li Suica, Oyster, lossis Octopus card):
Lub ICyog cov nti me me hauv cov yas uas paub tias tshuav nyiaj npaum li cas ntawm koj tus account.
Lub NFCyog cov thev naus laus zis uas tso cai rau lub turnstile "hais" rau lub nti thaum koj coj mus rhaub nws, txiav tus nqi hauv milliseconds.
Cov ntsiab lus
Yog tias koj muajNFC daim npav, nwsmuajibIC nti. Txawm li cas los xij, tsis yog txhua tusIC ntiyog ibNFC nti-qee yog txhais tau tias yuav tsum tau ntsaws, thiab qee qhov siv xov tooj cua sib txawv (xws li ntev -ntau RFID siv hauv cov tsev khaws khoom).
