Hlobo luni lolwazi olungabhalwa kumathegi e-NFC

I-NFC (Near Field Communication) iwukuvela kobuchwepheshe be-RFID; I-NFC inika amandla ukuxhumana okungenantambo okuvikelekile phakathi kwamadivayisi amabili, ngokushintshisana okuhlobene kwedatha.
Ubuchwepheshe be-NFC, obusetshenziswa ku-smartphone noma kuthebhulethi, buvumela:
ukushintshana kolwazi phakathi kwemishini emibili, ephephe ngokuphelele futhi esheshayo, ngokusondela nje (nge-Peer-to-peer);
ukwenza izinkokhelo ezisheshayo nezivikelekile ngomakhalekhukhwini (nge-HCE);
ukufunda noma ukubhala NFC Tags.
Ayini amathegi e-NFC
Omaka be-NFC bangama-transponder e-RFID asebenza ku-13.56 MHz. Ama-chips amancane (amasekhethi ahlanganisiwe) axhunywe ku-antenna. I-chip ine-ID ehlukile kanye nengxenye yememori ebhalwe kabusha. I-antenna ivumela i-chip ukuthi ixhumane nesifundi/isithwebuli se-NFC, njenge-smartphone ye-NFC.
Ungabhala ulwazi kumemori etholakalayo ye-NFC Chip. Lolu lwazi lungafundwa kalula (futhi lwenziwe) ngedivayisi ye-NFC, njenge-smartphone noma ithebhulethi. Kufanele nje uthephe i-Tag ngedivayisi yakho.

Usayizi nefomethi
Uhlobo oluvame kakhulu lwethegi ye-NFC isitika, okuyilebula eliqukethe isekhethi kanye nothi. Ngenxa yobukhulu babo obuncane, nokho, amathegi e-NFC angahlanganiswa kalula kuzisekelo eziningi, njengekhadi, ibhande lesandla, indandatho yokhiye, igajethi, njll. Into efakwe i-NFC Tag ingabonakala ngendlela ehlukile ngenxa yekhodi eyingqayizivele. kwe-chip.
Ukunikezwa kwamandla kagesi
Isici esithakazelisa kakhulu samathegi e-NFC ukuthi awadingi noma yikuphi ukunikezwa kwamandla aqondile, ngoba acushwa ngokuqondile yinkundla kazibuthe yenzwa ye-NFC yeselula noma idivayisi ewafundayo. I-Tag ingahlala inamathele entweni iminyaka futhi iqhubeke nokusebenza ngaphandle kwezinkinga.
Inkumbulo
Inkumbulo etholakalayo yamathegi e-NFC iyahlukahluka kuye ngohlobo lwe-chip, kodwa ngokuvamile kwabajwayeleke kakhulu ingaphansi kwekhilobhayithi engu-1. Lokhu kungase kubonakale njengomkhawulo, kodwa empeleni amabhayithi ambalwa kuphela anele ukuthola imisebenzi emangalisayo, ngenxa yezinga le-NDEF, ifomethi yedatha ye-NFC efakwe ikhodi yi-NFC Forum. Omunye wemisebenzi evame kakhulu ekukhangiseni, isibonelo, ukuhlela kwe-URL ebhekisela ekhasini lewebhu. I-Tag, ehlelwe kanjalo, ingasetshenziswa kunoma iyiphi into, incwajana, iflaya. Ngalo msebenzi, afana neKhodi ye-QR, kodwa afakwe umthamo omkhulu wedatha, okuwenza abe wusizo esimweni semibiko nokuhlaziywa komkhankaso. Ngaphezu kwalokho, zingenziwa ngezifiso ngezithombe zazo futhi azidingi, okungenani ku-Android, noma yiluphi uhlelo lokusebenza okufanele lufundwe. Ngaphezu kwalokho, inkumbulo ye-NFC Tag ihlukaniswe ngamabhulokhi amaningana, angasetshenziselwa ukuthuthukiswa kwezinhlelo zokusebenza eziyinkimbinkimbi (i-inventory, ikhadi lezokwelapha, njll.).
I-ID ehlukile
Wonke Amathegi e-NFC anekhodi ehlukile, ebizwa nge-UID (I-ID Eyingqayizivele), etholakala emakhasini angu-2 okuqala ememori, akhiyiwe (angeke ashintshwe noma asuswe). Nge-UID, ungakwazi ukubhanqa i-NFC Tag entweni noma kumuntu, futhi uthuthukise izinhlelo zokusebenza ezibakhomba futhi zihlanganyele nabo.
Hlobo luni lolwazi olungabhalwa kumathegi e-NFC?
Ku-NFC Tag ungabhala izinhlobo eziningi zolwazi. Okunye kwalokhu okokusetshenziswa kwangasese:
vumela/khubaza i-Wi-Fi
vumela/cisha i-Bluetooth
vumela/cisha i-GPS
vula/vala uhlelo lokusebenza
njalo njalo…
