NFC ipfupi-renji isina waya yekutaurirana tekinoroji.Iyi tekinoroji yakavapo kubva kune isingabatane neredhiyo frequency identification (RFID) uye yakagadziridzwa pamwe chete naPhilips Semiconductors (ikozvino NXP Semiconductors), Nokia uye Sony, zvichibva paRFID uye interconnect tekinoroji.

Near Field Communication ipfupi-renji, yakakwirira-frequency radio tekinoroji inoshanda kureba kwemasendimita gumi pa13.56MHz.Iyo yekumhanyisa kumhanya ndeye 106Kbit/sec, 212Kbit/sec kana 424Kbit/sec.

NFC inobatanidza mabasa emuverengi asingabatanidzi, kadhi risingabatanidzi uye peer-to-peer pane imwe chip, inogonesa chiziviso uye kuchinjanisa data nemidziyo inowirirana pamusoro pemadaro mapfupi.NFC ine nzira nhatu dzekushanda: inoshanda mode, passive mode uye bidirectional mode.
1. Active mode: Mumodhi inoshanda, kana mudziyo wega wega uchinge wada kutumira data kune imwe mudziyo, inofanirwa kugadzira yayo redhiyo frequency ndima, uye ese ari maviri mudziyo wekutangisa uye mudziyo unonangwa unofanirwa kugadzira yavo yeredhiyo frequency ndima yekutaurirana.Iyi ndiyo yakajairwa modhi yekutaurirana-kune-vezera uye inobvumira kukurumidza kwekubatanidza kuseta.
2. Passive communication mode: The passive communication mode inongopesana neyekushanda mode.Panguva ino, iyo NFC terminal inotevedzerwa sekadhi, iyo inongopindura zvishoma kune redhiyo frequency ndima inotumirwa nemimwe michina uye inoverenga / inonyora ruzivo.
3. Two-way mode: Mune iyi modhi, mativi ose eNFC terminal anoshingairira kutumira redhiyo frequency field kuti itange kutaurirana-ku-ku-point.Yakaenzana kune ese maNFC zvishandiso mune inoshanda modhi.

NFC, seyakakurumbira pedyo nemunda kutaurirana tekinoroji mumakore achangopfuura, inoshandiswa zvakanyanya.NFC application inogona kukamurwa kuita matatu anotevera emhando mhando

1. Kubhadhara
NFC yekubhadhara application inonyanya kureva kushandiswa kwenharembozha ine NFC basa kutevedzera kadhi rebhangi, kadhi uye zvichingodaro.Iyo NFC yekubhadhara application inogona kukamurwa kuita zvikamu zviviri: yakavhurika-loop application uye yakavharwa-loop application.Iko kushandiswa kweNFC kunoitwa mukadhi rebhangi kunonzi yakavhurika-loop application.Sezvineiwo, nhare mbozha ine NFC inoshanda uye kuwedzera analog kadhi rebhangi rinogona kushandiswa sekadhi rebhangi kutsvaira nharembozha pamichina yePOS muzvitoro zvikuru nezvitoro.Nekudaro, nekuda kwekukurumbira kweAlipay neWeChat kuChina, chikamu chaicho cheNFC mukubhadhara kwemudzimba zvikumbiro zvishoma, uye zvakanyanya kubatanidzwa uye kuunganidzwa neAlipay neWeChat Pay senzira yekubatsira Alipay neWeChat Pay kuti uzivikanwe. .

Iko kushandiswa kweNFC kutevedzera kadhi-kadhi kunonzi yakavharwa-loop application.Parizvino, kuvandudzwa kweNFC yakavharwa-loop application muChina haina kunaka.Kunyangwe hurongwa hwekufambisa kwevanhu mune mamwe maguta hwakavhura basa reNFC renharembozha, harina kufarirwa.Kunyangwe mamwe makambani enharembozha akayedza basa reNFC kiredhi kadhi renharembozha mune mamwe maguta, kazhinji anofanirwa kumisa mari yebasa.Nekudaro, zvinotendwa kuti nekuzivikanwa kweNFC nharembozha uye nekuenderera mberi kwehunyanzvi hweNFC, iyo kadhi-kadhi system zvishoma nezvishoma ichatsigira kushandiswa kweNFC nharembozha, uye iyo yakavharwa-loop application ichava neramangwana rakajeka.

2. Chengetedzo application
Iko kushandiswa kweNFC kuchengetedza kunonyanya kuita kuti nharembozha dzive makadhi ekudzora kupinda, matikiti emagetsi, nezvimwe. Iyo NFC chaiyo yekuwana yekudzora kadhi ndeyekunyora iripo yekudzora kadhi data muNFC yenharembozha, kuitira kuti yekupinda kutonga basa. inogona kuonekwa nekushandisa nharembozha ine NFC basa rekuvhara pasina kushandisa smart kadhi.Iko kushandiswa kweNFC chaiyo yemagetsi tikiti ndeyekuti mushure mekunge mushandisi atenga tikiti, iyo yetiketi system inotumira ruzivo rwetikiti kunhare mbozha.Nharembozha ine basa reNFC inogona kuita kuti ruzivo rwetikiti ruite tikiti remagetsi, uye nhare mbozha inogona kutsvaira zvakananga pacheki yetikiti.Iko kushandiswa kweNFC mune yekuchengetedza system inzvimbo yakakosha yeNFC application mune ramangwana, uye tarisiro yakakura kwazvo.Iko kushandiswa kweNFC mundima iyi hakugone chete kuchengetedza mutengo wevashandisi, asi zvakare kuunza yakawanda nyore kune vashandisi.Kushandisa nharembozha kutsiva makadhi ekudzora kupinda kwemuviri kana magineti kadhi matikiti anogona kudzikisa mutengo wekugadzira zvese kusvika padanho rakati, uye panguva imwechete kufambisa vashandisi kuvhura uye swipe makadhi, kuvandudza dhigirii re automation kusvika pamwero wakati, kuderedza. mutengo wekubhadhara vashandi vanopa kadhi uye kuvandudza kushanda kwesevhisi.

3. NFC tag application
Iko kushandiswa kweiyo NFC tag ndeyekunyora rumwe ruzivo muNFC tag, uye mushandisi anogona kubva awana ruzivo rwakakodzera nekungotsvaira tag yeNFC neNFC nharembozha.Semuenzaniso, vatengesi vanogona kuisa ma tag eNFC ane maposta, ruzivo rwekusimudzira, uye zviziviso pamusuwo wechitoro.Vashandisi vanogona kushandisa nharembozha dzeNFC kuwana ruzivo rwakakodzera zvinoenderana nezvavanoda, uye vanogona kupinda mumasocial network kuti vagovane ruzivo kana zvinhu zvakanaka neshamwari.Parizvino, ma tag eNFC anoshandiswa zvakanyanya mumakadhi ekupinda nguva, makadhi ekudzora kuwana uye makadhi ebhazi, nezvimwewo, uye iyo NFC tag ruzivo inotaridzwa uye inoverengwa kuburikidza neyakakosha NFC yekuverengera mudziyo.

Handheld-wirelessyanga yakatarisana nekusimudzira uye kugadzirwa kwemidziyo yeIoT yakavakirwa paRFID tekinoroji kwemakore mazhinji, ichipa vatengi zvigadzirwa zvakagadzirirwa uye masevhisi anosanganisira.RFID kuverenga nekunyora michina, NFC handsets,barcode scanners, biometric handhelds, emagetsi tags uye ane hukama application software.
