Iindaba

I-NFC bubuchwephesha bonxibelelwano olungenazingcingo.Le teknoloji yavela kwi-non-contact radio frequency identification (RFID) kwaye yaphuhliswa ngokudibeneyo yi-Philips Semiconductors (ngoku eyi-NXP Semiconductors), iNokia kunye ne-Sony, ngokusekelwe kwi-RFID kunye ne-interconnect technology.

I-Near Field Communication luhlobo olufutshane, itekhnoloji yerediyo yefrikhwensi ephezulu esebenza kumgama weesentimitha ezili-10 kwi-13.56MHz.Isantya sothumelo yi-106Kbit/sec, 212Kbit/sec okanye 424Kbit/sec.

I-NFC idibanisa imisebenzi ye-contactless reader, ikhadi loqhagamshelwano kunye ne-peer-to-peer kwi-chip enye, i-identification evumela ukuchongwa kunye nokutshintshiselana kwedatha kunye nezixhobo ezihambelanayo kwiindlela ezimfutshane.
1. Imo esebenzayo: Kwimo esebenzayo, xa isixhobo ngasinye sifuna ukuthumela idatha kwesinye isixhobo, kufuneka sivelise indawo yaso yefrikhwensi yerediyo, kwaye zombini isixhobo esiqalisayo kunye nesixhobo ekujoliswe kuso kufuneka sivelise indawo yaso yefrikhwensi yerediyo yonxibelelwano.Le yimowudi esemgangathweni yokunxibelelana koontanga kwaye ivumela ukuseta uqhagamshelo olukhawulezayo.
2. Imo yonxibelelwano: Imo yonxibelelano yokwenziwa ichasene nje nemo esebenzayo.Ngeli xesha, i-terminal ye-NFC ifaniswe njengekhadi, eliphendula kuphela ngokuqhubekayo kwindawo yefrikhwensi yerediyo ethunyelwa zezinye izixhobo kwaye ifunde/ibhala ulwazi.
3. Imowudi yeendlela ezimbini: Kule mowudi, omabini amacala etheminali ye-NFC ngokukhutheleyo athumela ibala lefrikhwensi yerediyo ukuseka unxibelelwano lwendawo ukuya kwindawo.Ilingana nezixhobo zombini ze-NFC kwimowudi esebenzayo.

I-NFC, njengeteknoloji yonxibelelwano ekufutshane nentsimi kwiminyaka yakutshanje, isetyenziswa ngokubanzi.Usetyenziso lwe-NFC lunokwahlulwa ngokwezi ntlobo zintathu zilandelayo

1. Intlawulo
Isicelo sentlawulo ye-NFC ikakhulu sibhekisa kusetyenziso lwefowuni ephathwayo enomsebenzi we-NFC ukulinganisa ikhadi lebhanki, ikhadi njalo njalo.Isicelo sentlawulo ye-NFC sinokwahlulwa sibe ngamacandelo amabini: isicelo esivulelekileyo kunye nesicelo esivaliweyo.Usetyenziso lwe-NFC oluyinyani kwikhadi lebhanki lubizwa ngokuba lusetyenziso oluvulelekileyo.Ngokufanelekileyo, ifowuni ephathwayo enomsebenzi we-NFC kunye nokongeza ikhadi lebhanki le-analog linokusetyenziswa njengekhadi lebhanki ukuswayipha ifowuni ephathwayo koomatshini be-POS kwiivenkile ezinkulu nakwiindawo zokuthenga.Nangona kunjalo, ngenxa yokuthandwa kwe-Alipay kunye ne-WeChat e-China, elona candelo le-NFC kwizicelo zentlawulo yasekhaya lincinci, kwaye liqhagamshelwe ngakumbi kwaye lihlanganiswe ne-Alipay kunye ne-WeChat Pay njengendlela yokuncedisa i-Alipay kunye ne-WeChat Pay yokuqinisekisa isazisi. .

Usetyenziso lwe-NFC olulinganisa ikhadi elinye lubizwa ngokuba lusetyenziso oluvaliweyo.Okwangoku, uphuhliso lwe-NFC oluvaliweyo lwezicelo e-China alufanelekanga.Nangona inkqubo yezothutho zikawonke-wonke kwezinye izixeko ivule umsebenzi we-NFC weefowuni eziphathwayo, ayizange yaziwe.Nangona ezinye iinkampani zeefowuni eziphathwayo ziye zavavanya umsebenzi wekhadi lebhasi le-NFC kwezinye iidolophu, ngokubanzi kufuneka zivule imirhumo yenkonzo.Nangona kunjalo, kukholelwa ukuba ngokuthandwa kweefowuni ze-NFC kunye nokukhula okuqhubekayo kobuchwepheshe be-NFC, inkqubo yekhadi enye iya kuxhasa ngokuthe ngcembe ukusetyenziswa kweefowuni ze-NFC, kwaye isicelo esivaliweyo siya kuba nekamva eliqaqambileyo.

2. Isicelo sokhuseleko
Ukusetyenziswa kokhuseleko NFC ikakhulu ukuba virtualize mobile phones zibe amakhadi olawulo ukufikelela, amatikiti elektroniki, etc. I NFC virtual ukufikelela ikhadi lolawulo ukubhala idatha ekhoyo yolawulo lwekhadi kwi-NFC yefowuni ephathwayo, ukuze umsebenzi wolawulo ukufikelela. inokuqondwa ngokusebenzisa ifowuni ephathwayo kunye NFC umsebenzi block ngaphandle kokusebenzisa ikhadi smart.Ukusetyenziswa kwetikiti le-NFC lenyani le-elektroniki kukuba emva kokuba umsebenzisi ethenge itikiti, inkqubo yetikiti ithumela ulwazi lwetikiti kwifowuni ephathwayo.Ifowuni ephathwayo enomsebenzi we-NFC inokwenza ulwazi lwetikiti lube kwitikiti lombane, kwaye ifowuni ephathwayo inokuswayipha ngokuthe ngqo kwitshekhi yetikiti.Ukusetyenziswa kwe-NFC kwinkqubo yokhuseleko yintsimi ebalulekileyo yesicelo se-NFC kwixesha elizayo, kwaye ithemba libanzi kakhulu.Ukusetyenziswa kwe-NFC kulo mmandla akunakugcina kuphela iindleko zabaqhubi, kodwa kuzisa lula kakhulu kubasebenzisi.Ukusebenzisa iifowuni eziphathwayo ukubuyisela amakhadi okulawula ukufikelela ngokwasemzimbeni okanye amatikiti ekhadi lemagnethi kunokunciphisa iindleko zokuvelisa zombini ukuya kuthi ga kwinqanaba elithile, kwaye kwangaxeshanye kube lula ukuba abasebenzisi bavule kwaye baswayiphe amakhadi, baphucule inqanaba lokuzenzekelayo ukuya kuthi ga kwinqanaba elithile. iindleko zokuqesha abasebenzi abakhupha amakhadi kunye nokuphucula ukusebenza kakuhle kwenkonzo.

3. Isicelo sethegi ye-NFC
Usetyenziso lwethegi ye-NFC kukubhala ulwazi oluthile kwithegi ye-NFC, kwaye umsebenzisi angafumana ngoko nangoko ulwazi olufanelekileyo ngokuswayipha nje ithegi ye-NFC ngefowuni ye-NFC ephathwayo.Umzekelo, abarhwebi banokubeka iithegi ze-NFC ezineepowusta, ulwazi lwentengiso, kunye neentengiso kumnyango wevenkile.Abasebenzisi banokusebenzisa iifowuni eziphathwayo ze-NFC ukufumana ulwazi olufanelekileyo ngokweemfuno zabo, kwaye banokungena kwiintanethi zentlalo ukuze babelane ngeenkcukacha okanye izinto ezintle nabahlobo.Okwangoku, iithegi ze-NFC zisetyenziswa ngokubanzi kumakhadi okuhamba kwexesha, amakhadi okulawula ukufikelela kunye namakhadi ebhasi, njl., kunye nolwazi lwethegi ye-NFC ichongiwe kwaye ifundwe ngesixhobo sokufunda esikhethekileyo se-NFC.

I-Handheld-wirelessibigxile kuphuhliso kunye nokuveliswa kwezixhobo ze-IoT ezisekwe kubuchwephesha beRFID iminyaka emininzi, ukubonelela abathengi ngeemveliso ezilungiselelwe kunye neenkonzo ezibandakanya.Izixhobo zokufunda nokubhala zeRFID, NFC handsets,izikena zebhakhowudi, ii-handheld zebhayometriki, iithegi ze-elektroniki kunye nesoftware yesicelo esinxulumeneyo.
