I-RFID VIP Lanyards: Yini Empeleni Evikela Ukufinyelela Komcimbi (nokuthi Okubukeka Kuphephile Kuphela)

Hamba noma yimuphi umcimbi omkhulu futhi i-VIP lanyard iwubufakazi obubonakalayo esizeni. Futhi, kaningi kunalokho, iyona ecutshungulwa kancane ku-oda lokuthenga. Ilogo, umbala, i-chip "yokufinyelela": igunyaziwe. Lelo gebe phakathi kokuthi ukuqinisekiswa kwe-premium kubukeka kanjani kanye nalokho okuphoqelelwa yi-RFID VIP lanyard kulapho izinkinga eziningi zokufinyelela ze-VIP ziqala khona.

 

Lokhu kubhalelwe abantu abangabanikazi baleso sinqumo: imisebenzi yomcimbi ihola,{0}}kubaphathi besayithi, amathimba endawo, kanye nabahlanganisi bacacisa izifakazo zamakhonsathi, izingqungquthela, nezindawo ezilawulwayo. Iphuzu lapha akukona ukukuthengisa nge-RFID. Okokukusiza ukuthi utshele imininingwane evikela isigaba se-VIP kulelo elivela kuphela.

 

 

I-lanyard ingasuswa, futhi lokho kushintsha wonke umbuzo wokuphepha

 

Nali iqiniso elingemnandi abahlinzeki abaningi beqa isikhathi esidlule. I-lanyard, ngokuklama, iyasuswa. Lapho umnikazi wangempela esula isango, imininingwane ingaphuma futhi iphindele emuva ngothango iye kothile olindile ngaphandle. Imiswe ngokumelene nokushisa{3}}okuvaliwe kwebhande esihlakaleni elichithwa ngokuphumelelayo ekususweni, iI-RFID lanyard vs i-wristbandUkuqhathanisa kuwumbuzo owodwa ofihliwe: ukudluliswa. I-wristband imelana nokudlula{1}}ngemuva ngokwesakhiwo; i-lanyard ayifuni. Uma ukudlula{3}}ukumelana nokuhlehla kuwumthwalo wakho wokuqala, wethuI-RFID wristbands yefestivali kanye{0}}nokufinyelela kwezinsuku eziningiziyifomethi eyakhelwe yona.

 

Akukho kulokhu okwenza i-lanyard ingafaneleki. Iyayihlela kabusha. Ilanyard izuza indawo yayo ngoba igqoka kamnandi ezinsukwini eziningi, iphinde ikhishwe ngemizuzwana, futhi ibhangqwa ngokwemvelo nesibambi sebheji ne-ID yesithombe. Engakwazi ukukwenza ukuphoqelela ubuwena ngokwayo.

 

Isimo sami esibucayi ngemva kweminyaka yalokhu kwakha: ibhande elikhiphekayo eligunyazwe kuphela inombolo ye-chip alikona ukulawula ukufinyelela, liwumhlobiso onezinhloso ezinhle ezinamathiselwe. Ukuze uziphathe njengesibambiso, isitifiketi se-VIP ku-lanyard kufanele siboshwe kubunikazi obubhalisiwe, futhi ngokufanelekile ebusweni{1}}emasangweni amanani aphezulu.

 

Ikhadi lingena kuphi, njengoba kuyifomu lesithathu abathengi abakalayo? Ikhadi liyasebenziseka kabusha,{0}}lifakwe kalula kalula{0}}lokufaka ikhodi, futhi linethezekile{1}}i-microprocessor chip ephakeme kakhulu, okuyenza ibe ukukhetha okungokwemvelo kwabasebenzi, ubulungu, kanye nezigaba ezibuyayo{2}}ze-VIP ozikhipha kabusha isizini nesizini. Kodwa ikhadi lihlanganyela ubuthakathaka be-lanyard: liyahlehla futhi likhiphe izandla kalula nje, futhi lilahlekelwa ukubona{-ukubuka,-okugugileyo njalo intambo yentamo inika umphathi. Okokusebenziseka kabusha,{8}}izigaba zokuphepha eziphezulu, zethuAmakhadi e-RFID e-VIP kanye nezigaba zobulunguvala leso siphetho; okokuhlonza{{0}okugqokwayo kwansuku zonke, okusheshayo{1}okukhishwe kabusha kwe-VIP, i-lanyard isawina ngokunethezeka nangesivinini.

 

Ilotho ye-chip: kungani "i-RFID lanyard" ku-quote isho cishe lutho

 

 

Imininingwane eminingi yokuthenga ithi "RFID lanyard" bese ima lapho. Lowo mugqa owodwa ufihla ukukhetha okubaluleke kakhulu esakhiweni sonke, ngoba "i-RFID" ihlanganisa ama-chips ahlukene ngomhlaba kwezokuphepha.

 

Okuzenzakalelayo{0}}umthengisi wezindleko eziphansi azifinyelelayo kuvame ukuba yi-chip yomndeni ye-MIFARE Classic{1}}, noma okulingana ne-"MIFARE{2}}okuhambisanayo" okungagunyaziwe. I-Crypto1 cipher yalowo mndeni yaphuka eminyakeni edlule futhi inganqotshwa ngehadiwe eshibhile, etholakala kabanzi. Bese kuba kubi kakhulu: ngo-2024, abacwaningi badalula i-backdoor ye-hardware ezigidini zama-chips e-Fudan FM11RF08S kanye ne-FM11RF08 evumela umhlaseli ukuthi ahlanganise ikhadi ngemva kwemizuzu nje yokusondelana ngokomzimba, futhi bathola ukuthi lawo ma-chips ayesakazeke buthule kumasistimu okufinyelela kulo lonke elase-US naseYurophu (Iviki Lokuphepha). Umthengi o-ode "i-RFID lanyard yangokwezifiso" ngaphandle kokuqamba i-chip kungenzeka ukuthi ubambe lokhu futhi angazi.

 

Kukhona imodi yesibili, ethule yokwehluleka: amasistimu afakazela ubuqiniso ku-UID ye-chip kuphela. I-UID ayiyona imfihlo. Amathegi angenalutho, abhalekayo avumela noma ubani ukuthi asethe i-UID engafanele, ukuze i-UID-ingumfundi kuphela ongakhohliswa i-clone ebiza ukushintshwa kwe-pocket ukukhiqiza. Ukuze uthole i-primer egcwele yokuthi imindeni yama-chip namafrikhwensi imephu kuzinhlelo zokusebenza zangempela, yethuumhlahlandlela we-chip ye-RFID nokukhetha kokuqinisekisauhamba phakathi kwe-tradeoffs. Emsebenzini we-VIP okuthathayo kufushane: umndeni we-chip kanye nendlela yokuqinisekisa, hhayi igama elithi "RFID," inquma ukuthi ingabe imininingwane yakho iyamelana yini nokwenziwa.

 

Ukukhethwa kwe-chip, kuqhathaniswa

 

Umndeni we-chip	Imodeli yokuphepha	Ukumelana nama-Clone	Ilungele ukusetshenziswa kwe-VIP
I-MIFARE Classic / iyahambisana	I-Legacy Crypto1, ngokuvamile i-UID{1}}isebenza kuphela	I-cipher ephukile - ephansi, iminyango yangemuva eyaziwayo	Gwema ukufinyelela; kubekezelelwa kuphela ukubalwa kokulahla,{0}okungavikelekile
I-MIFARE DESFire (EV2/EV3)	I-AES / 3DES, i-microprocessor, ukuhlukahluka kokhiye	High - alikho ikhadi elisebenzayo-kuphela i-clone	Ukufinyelela{0}zoni okuningi, isiteji sangemuva, izigaba zabasebenzi
I-NTAG 424 DNA	I-AES enomlayezo-osayiniwe ngokuthepha (SUN/SDM)	Okuphezulu kakhulu - kokuthepha ngakunye kunikeza ubufakazi obusha be-cryptographic	Anti{0}}ukuthengisa kabusha i-VIP, cindezela, imininingwane yokunethezeka, ifoni{1}}engaqinisekiswa

 

Umthetho wokusebenza: uma i-lanyard ibusa ukungena endaweni ekhawulelwe, imininingwane iyingxenye yomugqa we-DNA we-DESFire noma we-NTAG 424, nokhiye abahlukanisiwe ngemininingwane ngayinye ukuze ukufaka engcupheni ithegi eyodwa kungatsheli umhlaseli lutho ngokulandelayo. Leso sinqumo sokucaciswa esisodwa senza okuningi ekuvikelekeni kwe-VIP kunanoma iyiphi i-premium weave noma ikhodi yombala eyoke ikwenze.

 

Lapho leso simiso sivumelana nezimo ukuphatha okubalulekile-kumcimbi wezinsuku eziningi, ngenxa yokuthi ukukhishwa kabusha kwelanyard ye-VIP elahlekile ngosuku lwesibili kusho{1}}ukunikeza okhiye abahlukahlukene esangweni, hhayi nje ukuphrinta ibhande elisha: okuhlukile okuningi akukaze kukhulume kanye naleyo enquma buthule ukuthi "okhiye abahlukahlukene" bayasinda yini lapho bexhumana nomnyango ophilayo. Sithumelele imephu yendawo futhi uphinde ukhiphe i-cadence futhi sizomaka ukuthi iyiphi i-chip tier isango ngalinye elidinga ngempela.

 

I-UHF noma i-HF/NFC? Qondanisa imvamisa nesango, hhayi incwajana

 

Imvamisa ithengiswa-njengenani elithile leshidi uma kuyinketho yokuziphatha. -Imvamisa ephezulu kanye nemininingwane ye-NFC efundwa ngamasentimitha ambalwa futhi iklomelise ngokuthepha ngamabomu; Izifakazelo ze-UHF zifundwa kumamitha ambalwa futhi zinikwa umvuzo,{3}}ekuthwebuleni{4} kwebanga. Futhi akukho "ngcono." Bagqekeza ezindaweni ezahlukene, nohlelo olubucayi olwakhelwe phezu kwaloI-RFID yokulawula ukufinyelela komcimbi i-lanyardi-hardware ngokuvamile idinga kokubili ezindaweni ezahlukene kusayithi.

 

Ihlukanise ngokwesimo. Ekungeneni okunomuntu noma emnyango wendawo, ibheji yomcimbi we-NFC iyithuluzi elilungile, ngoba ibanga elifushane lokufunda lenza ukuthi ukuthepha kube ngenhloso, kube nzima ukugxuma esixukwini, futhi kube lula ukubhangqwa -nokuhlolwa kwesithombe sesikrini, ukusethwa okuguqula izifakazelo ze-RFID ze-VIP nokufinyelela ngemuva kwesiteji kube into umqondisi angayethemba ngempela. Ukuze uthole izibalo zokunyakaza ngaphakathi kwendawo, njengesikhathi sokuhlala endaweni yokuphumula noma ukugeleza phakathi kwezindawo, ibanga lokufunda le-UHF lizuza ukugcinwa kwalo ngokubamba izifakazelo ngaphandle kokuma. Ngokusebenzisa imali okungenakheshi kubha ye-VIP, thepha-bese-uhambe ukuthi i-NFC iyawina futhi ngokwenziwe ngamabomu,{6}}ukuya{7}}kukodwa.

 

Ukuqhuba umnyango oqinile-kububanzi be-UHF obude kumema ukwehluleka okungekho muntu okubeka ku-spec: ama-VIP amaningana ahlanganiswe emnyango omncane, omaka bawo bayashayisana endaweni yokufunda, kanye nesistimu eqinisekisa umuntu ongalungile, noma akukho muntu nhlobo.

 

Lokho okufakazelwa ukuthunyelwa kwangempela, nalokho okuvezwa abambalwa buthule

 

 

Amafestivali amakhulu asuka ekuhloleni mathupha aya ekuhloleni ngaphandle kokuthinta{0}}abhale phansi ngokusobala. Ukukhishwa kwe-RFID ye-Coachella kubikwe ukuthi cishe kuphindwe kabili-ngomzila ngamunye wokuphuma kwesango, kusukela ekungeneni okungaba ngu-1,000 kuya ku-2,500 ngehora, kuyilapho i-Tomorrowland ibike izikhathi zomugqa ophezulu zehle ngaphezu kuka-80% njengoba inani lababekhona likhule cishe ngo-12%. Ngasohlangothini lwezohwebo, izinhlelo ze-RFID ezingenakheshi zivame ukuphakamisa{10}}isithameli ngasinye esichitha imali ebangeni elingu-15–30%, kanti ukuhlanganiswa kwemali kwe-Coachella kubikwe eduze kuka-25%. Amasistimu{15}ashuniwe kahle abambe ukuthembeka kokufunda ngaphezu kuka-99.7% ekungeneni okuphezulu. Lezo izinombolo ezithethelela into yomugqa.

 

Abacwaningi bezokuphepha balokhu befakazela ububi emishinini efanayo. Bafunde ngokuphindaphindiwe futhi babhala kabusha amabhande ehlakala omcimbi namabhendi angenakheshi akhelwe phezu kwe-MIFARE Classic ephukile kungekho lutho olungaphezu kwefoni ngamaminithi, futhi ubuthakathaka obufanayo buhamba kunoma iyiphi intuba ethola i-chip efanayo. Ngisho namasistimu aqinile abamba ukuhlasela okubukhoma enkundleni: izifakazelo ezikhiqiza umlayezo omusha, osayiniwe kuyo yonke imizamo yokumaketha kampompi emasangweni -isistimu ye-chip engase izulise phakathi kwayo. Isifundo akukhona ukuthi i-RFID iyahluleka. Kungukuthi imininingwane yenza lokho kanye okuvunyelwa yi-chip yayo kanye ne-backend yayo, futhi akukho okunye.

 

Icacisa i-VIP lanyard ebambelelayo

 

Ingcuphe eningi engenhla iyahwamuka esigabeni sokucaciswa, inqobo nje uma i-spec ibiza izinto ezibalulekile kunezinto ezithwebula kahle. Ukuze uthole i-RFID lanyard yangokwezifiso yezingqungquthela noma{1}}ezehlakalweni zokufinyelela elawulwayo, gcizelela lezi zinto zomugqa:

 

• Umndeni we-Chip kanye nengxenye yenombolo ngokubhala: DESFIRE EV2/EV3 noma i-NTAG 424 DNA nganoma yisiphi isiqiniseko esivula indawo ekhawulelwe, kungalokothi "kuhambisana ne-MIFARE" okungashiwongo ngegama.
   
• Ukuhlukahluka kokhiye nokubethela kuqinisekisiwe:{0}}ngokhiye bokuqinisekisa,{1}ukuqinisekisa okusekelwe ku-AES{1}, kanye nesifundi kanye ne-backend eqinisekisa nge-cryptographically esikhundleni se-UID.
   
• Ukubophezela kobunikazi: ukubhaliswa okuxhumanisa imininingwane ngayinye kumphathi oqanjwe igama, nokuqinisekiswa kwesithombe emasangweni{0}}enani aphakeme kakhulu.
   
• Amazinga nokuqina: ISO/IEC 14443 ye-HF/NFC noma i-ISO/IEC 18000-63 ye-UHF, kanye ne-tamper{3}}okusobala, ukujuluka{4}} kanye ne-UV-ekwazi ukumelana ne-UV{5}}esindayo ukugqokwa kwezinsuku eziningi.
   
• Ibhalansi yokuvala nokuphepha: indawo enqamukile yokuphepha kwentamo, ikalwe ngokumelene neqiniso lokuthi ukukhululwa okulula futhi kunciphisa ukudluliselwa, ngakho-ke lapho uvumela ukwehlukana, ncika kakhulu ekubopheni ubunikazi.

 

I-specpe ehlanganisa lezo ezinhlanu zibambe phezulu ngaphansi kocwaningo. Lapho isaluma khona ukuxhumana phakathi kwazo: ukuvala okunqamukayo kanye nokudlula okuqinile-kudonsela emuva ukulawula okungemuva, nokuthi iyiphi ewinayo kuya ngesakhiwo sesango lakho nokuthi ungakwazi yini ukubeka ukuqinisekiswa kwesithombe esigabeni esiphezulu. Lokho kuhwebelana kuyingxenye uhlu lokuhlola lwesifanekiso olungakwazi ukukuxazululela lona; sithumelele uhlu lwezoni futhi sizocacisa ukuvalwa nokubophezela ukuze kufane nalo.

 

Lapho ubufakazi buvela khona ezindabeni

 

Lena ingxenye umphakeli oholwa yi-software kuphela abakwazi ukuphendula ngokwethembeka, ngoba bathenga ama-inlay ngendlela efanayo nawo wonke umuntu. Lapho ifekthri ibopha ama-chips ayo futhi ishuna ama-antenna ayo, ukukhetha kwe-chip kuyeka ukuba yimfihlakalo ekhishwa emgqonyeni. Kolayini wethu, ukusongwa kwe-antenna kubanjelwe ku-±0.1 mm ngakho-ke ibanga lokufunda lihlala lingashintshile ukusuka kumathegi kuye kumaka, futhi yonke imininingwane ihlolelwa imvamisa, ububanzi bokufundwayo, nobuqotho bedatha ngaphambi kokuba ithunyelwe, okuyindlela futhi i-chip ye-Classic egcinwa ngayo ngaphandle kwe-oda obekumele livikeleke. Lelo zinga lokulawula, elisekelwa izinqubo ze-ISO9001 kanye ne-CE kanye namashumi amabili eminyaka omlando wokwakha, liwumehluko phakathi komphakeli ongakwazi ukusho i-chip yakho nalowo othemba ukuthi ngeke ubuze.

Imibuzo evamile mayelana ne-RFID VIP lanyards
