NFC ndiukadaulo wolumikizana opanda zingwe wanthawi yayitali.Tekinoloje iyi idachokera ku chidziwitso cha ma radio frequency (RFID) ndipo idapangidwa limodzi ndi Philips Semiconductors (tsopano NXP Semiconductors), Nokia ndi Sony, kutengera RFID ndiukadaulo wolumikizana.

Near Field Communication ndi ukadaulo wapawayilesi wamfupi, wothamanga kwambiri womwe umagwira ntchito pamtunda wa 10 centimita pa 13.56MHz.Kuthamanga liwiro ndi 106Kbit/sec, 212Kbit/mphindi kapena 424Kbit/mphindi.

NFC imaphatikiza ntchito za owerenga osalumikizana, khadi losalumikizana ndi anzawo pa chip chimodzi, kupangitsa chizindikiritso ndi kusinthana kwa data ndi zida zofananira pamtunda waufupi.NFC ili ndi njira zitatu zogwirira ntchito: mawonekedwe ogwirira ntchito, mawonekedwe okhazikika komanso njira yolumikizirana.
1. Active mode: Mumode yogwira, chipangizo chilichonse chikafuna kutumiza deta ku chipangizo china, chiyenera kupanga gawo lake la mawayilesi a wailesi, ndipo chipangizo choyatsira ndi chomwe chalowera chiyenera kupanga gawo lawo la mawayilesi kuti athe kulumikizana.Iyi ndiye njira yolumikizirana ndi anzawo ndipo imalola kulumikizana mwachangu kwambiri.
2. Njira yolankhulirana mosasamala: Njira yolankhulirana yongolankhula ndi yosiyana ndi yogwira.Pakadali pano, terminal ya NFC imafaniziridwa ngati khadi, yomwe imangoyankha mosavutikira kugawo lawayilesi lotumizidwa ndi zida zina ndikuwerenga / kulemba zambiri.
3. Njira ziwiri: Munjira iyi, mbali zonse ziwiri za terminal ya NFC zimatumiza mwachangu gawo la mawayilesi kuti akhazikitse kulumikizana kolunjika.Zofanana ndi zida zonse za NFC zomwe zimagwira ntchito.

NFC, monga njira yodziwika bwino yolumikizirana yakumunda m'zaka zaposachedwa, imagwiritsidwa ntchito kwambiri.Ntchito za NFC zitha kugawidwa m'magulu atatu otsatirawa

1. Malipiro
Ntchito yolipira ya NFC imatanthawuza kugwiritsa ntchito foni yam'manja yokhala ndi ntchito ya NFC kutengera khadi la banki, khadi ndi zina zotero.Ntchito yolipira ya NFC imatha kugawidwa m'magawo awiri: pulogalamu yotsegula ndi pulogalamu yotseka.Kugwiritsa ntchito kwa NFC kukhala khadi yaku banki kumatchedwa ntchito yotsegula.Moyenera, foni yam'manja yokhala ndi ntchito ya NFC ndikuwonjezera khadi yakubanki ya analogi ingagwiritsidwe ntchito ngati khadi yakubanki kusuntha foni yam'manja pamakina a POS m'masitolo akuluakulu ndi malo ogulitsira.Komabe, chifukwa cha kutchuka kwa Alipay ndi WeChat ku China, gawo lenileni la NFC muzolipira zapakhomo ndi laling'ono, ndipo limalumikizidwa kwambiri ndi Alipay ndi WeChat Pay ngati njira yothandizira Alipay ndi WeChat Pay kuti mutsimikizire kuti ndinu ndani. .

Kugwiritsa ntchito kwa NFC kuyerekezera khadi limodzi kumatchedwa ntchito yotseka.Pakalipano, chitukuko cha mapulogalamu a NFC otsekedwa ku China si abwino.Ngakhale njira zoyendera anthu m'mizinda ina zatsegula ntchito ya NFC ya mafoni am'manja, sizinatchulidwe.Ngakhale makampani ena amafoni am'manja ayesa kugwiritsa ntchito makadi a mabasi a NFC m'mizinda ina, nthawi zambiri amayenera kuyimitsa chindapusa.Komabe, akukhulupirira kuti ndi kutchuka kwa mafoni a m'manja a NFC komanso kukhwima kosalekeza kwaukadaulo wa NFC, kachitidwe ka khadi limodzi kamathandizira pang'onopang'ono kugwiritsa ntchito mafoni a m'manja a NFC, ndipo kugwiritsa ntchito kotsekeka kudzakhala ndi tsogolo lowala.

2. Chitetezo ntchito
Kugwiritsa ntchito chitetezo cha NFC makamaka kupangitsa mafoni kukhala makhadi owongolera, matikiti amagetsi, ndi zina zambiri. Khadi la NFC lomwe limayang'anira mwayi wofikira ndi kulemba zomwe zilipo kale mu NFC ya foni yam'manja, kuti ntchito yowongolera mwayi wopezeka. zitha kuzindikirika pogwiritsa ntchito foni yam'manja yokhala ndi chipika cha NFC popanda kugwiritsa ntchito khadi yanzeru.Kugwiritsa ntchito tikiti yamagetsi yamagetsi ya NFC ndikuti wogwiritsa ntchito akagula tikiti, makina amatikiti amatumiza zambiri zamatikiti ku foni yam'manja.Foni yam'manja yokhala ndi ntchito ya NFC imatha kusinthira chidziwitso cha tikiti kukhala tikiti yamagetsi, ndipo foni yam'manja imatha kusunthidwa mwachindunji pacheke.Kugwiritsa ntchito NFC muchitetezo ndi gawo lofunikira kwambiri pakugwiritsa ntchito NFC m'tsogolomu, ndipo chiyembekezo chake ndi chachikulu kwambiri.Kugwiritsa ntchito NFC mu gawoli sikungangopulumutsa mtengo wa ogwiritsa ntchito, komanso kubweretsa mwayi wambiri kwa ogwiritsa ntchito.Kugwiritsa ntchito mafoni a m'manja kuti m'malo mwa makhadi owongolera anthu kapena matikiti a maginito kumatha kuchepetsa mtengo wopangira zonse mpaka pamlingo wina, ndipo nthawi yomweyo kumathandizira ogwiritsa ntchito kutsegula ndi swipe makhadi, kupititsa patsogolo kuchuluka kwa makina mpaka pamlingo wina. mtengo wolembera anthu opereka makhadi ndikuwongolera magwiridwe antchito.

3. NFC tag ntchito
Kugwiritsa ntchito tag ya NFC ndikulemba zambiri mu tag ya NFC, ndipo wogwiritsa ntchito atha kupeza zomwe zikuyenera pompopompo pongosuntha tag ya NFC ndi foni yam'manja ya NFC.Mwachitsanzo, amalonda atha kuyika ma tag a NFC okhala ndi zikwangwani, zotsatsa, ndi zotsatsa pakhomo la sitolo.Ogwiritsa ntchito amatha kugwiritsa ntchito mafoni a m'manja a NFC kuti adziwe zambiri malinga ndi zosowa zawo, ndipo amatha kulowa m'malo ochezera a pa Intaneti kuti agawane zambiri kapena zinthu zabwino ndi anzawo.Pakadali pano, ma tag a NFC amagwiritsidwa ntchito kwambiri pamakadi owerengera nthawi, makhadi owongolera mwayi ndi makhadi a basi, ndi zina zambiri, ndipo chidziwitso cha tag ya NFC chimadziwika ndikuwerengedwa kudzera pa chipangizo chapadera chowerengera cha NFC.

Wopanda m'manjayakhala ikuyang'ana kwambiri pakupanga ndi kupanga zida za IoT zozikidwa paukadaulo wa RFID kwazaka zambiri, kupatsa makasitomala zinthu ndi ntchito zosinthidwa makonda kuphatikizaZida zowerengera ndi kulemba za RFIDmafoni a NFC,barcode scanner, zonyamula m'manja za biometric, ma tag apakompyuta ndi mapulogalamu okhudzana ndi ntchito.
