Cov ntaub ntawv zoo li cas tuaj yeem sau rau hauv NFC Cim npe

NFC (Nyob ze Field Communication) yog ib qho kev hloov pauv ntawm RFID thev naus laus zis; NFC ua kom muaj kev ruaj ntseg wireless txuas ntawm ob lub cuab yeej, nrog rau kev sib pauv cov ntaub ntawv.
NFC thev naus laus zis, siv rau lub smartphone lossis ntsiav tshuaj, tso cai:
kev sib pauv ntaub ntawv ntawm ob lub cuab yeej, tag nrho muaj kev nyab xeeb thiab ceev, yooj yim los ntawm kev mus (ntawm Peer-to-peer);
kom them sai thiab tiv thaiv nrog cov xov tooj ntawm tes (ntawm HCE);
nyeem lossis sau NFC Cim npe.
Dab tsi yog NFC Tags
NFC cov cim npe yog RFID transponders uas ua haujlwm ntawm 13.56 MHz. Lawv yog cov chips me me (integrated circuits) txuas nrog lub kav hlau txais xov. Lub nti muaj ib tus ID tshwj xeeb thiab ib feem ntawm lub cim xeeb rov sau tau. Lub kav hlau txais xov tso cai rau lub nti cuam tshuam nrog NFC nyeem ntawv / tshuab luam ntawv, zoo li NFC smartphone.
Koj tuaj yeem sau cov ntaub ntawv ntawm lub cim xeeb muaj ntawm NFC Chip. Cov ntaub ntawv no tuaj yeem nyeem tau yooj yim (thiab raug tua) los ntawm NFC ntaus ntawv, zoo li smartphone lossis ntsiav tshuaj. Koj tsuas yog yuav tsum coj mus rhaub Cov Tag nrog koj lub cuab yeej.
Saib cov npe ntawm NFC-enabled Smartphones thiab Tablets
Loj thiab hom
Daim ntawv tshaj plaws ntawm NFC tag yog daim nplaum, uas yog daim ntawv lo uas muaj lub voj voog thiab lub kav hlau txais xov. Ua tsaug rau lawv qhov me me, txawm li cas los xij, NFC cim npe tuaj yeem yooj yim ua ke rau hauv ntau qhov kev txhawb nqa, xws li daim npav, lub dab teg, lub nplhaib tseem ceeb, khoom siv, thiab lwm yam. Ib qho khoom nruab nrog NFC Tag tuaj yeem txheeb xyuas tshwj xeeb ua tsaug rau cov cim tshwj xeeb. ntawm lub chip.
Fais fab mov
Ib qho nthuav heev ntawm NFC cov cim npe yog tias lawv tsis xav tau cov khoom siv hluav taws xob ncaj qha, vim tias lawv tau qhib ncaj qha los ntawm cov hlau nplaum ntawm NFC sensor ntawm lub xov tooj ntawm tes lossis cov cuab yeej nyeem lawv. Lub Tag tuaj yeem nyob twj ywm rau ib qho khoom rau xyoo thiab txuas ntxiv ua haujlwm yam tsis muaj teeb meem.
Nco
Lub cim xeeb muaj nyob ntawm NFC cov cim npe txawv raws li hom nti, tab sis feem ntau hauv cov feem ntau nws tsawg dua 1 kilobyte. Qhov no yuav zoo li muaj kev txwv, tab sis qhov tseeb tsuas yog ob peb bytes txaus kom tau txais txiaj ntsig zoo, ua tsaug rau NDEF tus qauv, cov ntaub ntawv hom ntawv rau NFC encoded los ntawm NFC Forum. Ib qho ntawm cov haujlwm tshaj plaws hauv kev lag luam, piv txwv li, yog qhov programming ntawm URL uas hais txog nplooj ntawv web. Lub Tag, yog li programmed, tuaj yeem siv rau txhua yam khoom, daim ntawv qhia, flyer. Nrog rau txoj haujlwm no, lawv zoo ib yam li QR Code, tab sis tau nruab nrog cov ntaub ntawv muaj peev xwm ntau dua, uas ua rau lawv muaj txiaj ntsig zoo rau cov ntaub ntawv tshaj tawm thiab kev tsom xam cov phiaj xwm. Tsis tas li ntawd, lawv tuaj yeem hloov kho nrog lawv tus kheej cov duab thiab tsis tas yuav, tsawg kawg rau Android, txhua daim ntawv thov yuav tsum tau nyeem. Tsis tas li ntawd, lub cim xeeb ntawm NFC Tag tau muab faib ua ob peb ntu, uas tuaj yeem siv rau kev txhim kho cov ntawv thov nyuaj (cov khoom muag, daim npav kho mob, thiab lwm yam).
Cim ID
Txhua NFC Cim npe muaj cov cim tshwj xeeb, hu ua UID (Unique ID), nyob hauv thawj 2 nplooj ntawv ntawm lub cim xeeb, uas raug kaw (tsis tuaj yeem hloov lossis tshem tawm). Los ntawm UID, koj tuaj yeem sib koom ua ke NFC Tag rau ib qho khoom lossis ib tus neeg, thiab tsim cov ntawv thov uas txheeb xyuas thiab cuam tshuam nrog lawv.
Cov ntaub ntawv dab tsi tuaj yeem sau rau ntawm NFC Cim npe?
Ntawm NFC Tag koj tuaj yeem sau ntau hom ntaub ntawv. Qee qhov no yog rau kev siv ntiag tug:
enable/disable Wi-Fi
pab / lov tes taw Bluetooth
pab / lov tes taw GPS
qhib/kaw ib daim ntawv thov
thiab lwm yam…
