I-Aluminiyam ye-Foil ye-RFID yokuvala iMikhono yokuSebenza kunye neSicelo

 

Indlela i-Aluminiyam yeFoil Sleeve ibhloka ngayo Iimpawu zeRFID

 

Xa ikhadi lihleli ngaphakathi kwendawo ebiyelweyo, indawo ebiyelweyo isebenza njengeIkheji yaseFaraday. Umaleko we-aluminiyam ubonakalisa kwaye ufunxa indawo ye-electromagnetic enokuthi umfundi wangaphandle aqhele ukusebenzisa ukunika amandla itshiphu yeRFID. Akukho ntsimi ifikelela kwi-chip, akukho datha eshiya ikhadi.

 

Oku kusebenza ngenxa yeubunzulu bolusu, ubukhulu bomqhubi ofunekayo ukuthothisa umqondiso malunga ne-63%. Kwi-13.56 MHz, amaxesha okusebenza kwamakhadi okuhlawula e-NFC kunye nezona ziqinisekiso zangoku ezikrelekrele, ubunzulu besikhumba se-aluminium bumalunga ne-0.018 mm. I-foil yasekhitshini eqhelekileyo ihamba malunga ne-0.016 mm ubukhulu. Isondele kakhulu.Ikhadi lorhwebo{0}}imikhono yokhuselekolaminate le foil phakathi kwephepha okanye umaleko wepolymer kwaye ugqithise ubunzulu bolusu olunye lwe-aluminiyam, ethi yehlise isignali ngaphantsi komqobo wokudityaniswa komgangatho wabafundi be-13.56 MHz.

Omnye umbuzo esiwufumana rhoqo eSyntek ubonisa ukubhideka. Umphathi wezibonelelo ucela i-RFID{1}}ibambi beebheji ebhlokile kubasebenzi abangama-200, echaza "i-RFID blocking" ngaphandle kokukhankanya amaxesha amaninzi. Siyabuza ukuba yeyiphi imodeli yomfundi esetyenziswa kwisakhiwo sabo. Malunga nesiqingatha sexesha, impendulo ijika ibe yi-HID ProxPoint okanye inkqubo efanayo ye-125 kHz. Ngelo xesha kufuneka sithe ngqo: yethuumkhono wekhadi le-aluminium foilibekwe kwi-13.56 MHz nangaphezulu. Iza kukhusela amakhadi entlawulo e-NFC, i-e{2}ipasipoti, kunye neziqinisekiso ezihlakaniphile ze-HF ngokufanelekileyo. Ayizi kubonelela ngokhuseleko oluthembekileyo kwiibheji ezikufutshane ze-125 kHz. Ukuba isixokelelwano sakho sisebenza nge-125 kHz, udinga{7}}umaleko oqhubekileyo wenjongo edibanisayo{8}}eyakhelwe uthomalaliso olusezantsi{9}} kwaye olo ludidi lwemveliso olwahlukileyo olunamaxabiso awohlukeneyo.

Imikhono ye-Passive Shielding vs

 

Iindidi ezimbini zeemveliso zifakwa phantsi kwe "RFID blocking," kodwa iindlela zokusebenza azinanto zifanayo. Ukubenza badideke kumyalelo wokuthenga yimpazamo elula eyenza isikali esibi.

 

Ingxaki ivela kwiindawo ezininzi-zekhadi. Uluhlu olusebenzayo lwekhadi le-jamming malunga ne-2 cm ukusuka kumphezulu walo. Beka ikhadi lokufikelela, ikhadi lokuhlawula, kunye nekhadi lokuhamba kwindawo enye, kwaye i-jammer ayinakufikelela kuzo zontathu. Iingxoxo kwiiforum zokhuseleko ze-hardware, kubandakanywa intambo ecacileyo ye-2025 kwibhodi yoluntu ye-Linus Tech Tips, ibhalwe amatyala apho ikhadi elilodwa elongezelelweyo phakathi kwe-jammer kunye ne-target credential yabangela ukuba i-jammer ingaphumeleli. Amalungu eForam yezinto ezinobungozi ahlolisise oku ngakumbi nge-HID iClass iziqinisekiso.

 

Umkhono wokwenziwa uyawuphelisa loo mahluko. Nokuba ikhadi lingaphakathi kwendawo ebiyelweyo yokuqhuba okanye ayikho. Ungaluqinisekisa ukhuselo ngokubona, kwaye ungaluvavanya kwimizuzwana elishumi: faka ikhadi, ubambe umkhono ngokuchasene nomfundi wakho. Ukuba umfundi akakwazi ukulibona ikhadi, umkhono uyasebenza.

 

Kwiinkqubo zeebheji zeshishini, imikhono iyaphumelela ngokuqikelelwa: ungazinikezela kubasebenzi abangama-300 kwaye uyazi ukuba ngamnye usebenza ngokufanayo. Amakhadi eJamming asebenziseka ngakumbi kusetyenziso lwe-wallet yobuqu, apho ukufaka kunye nokususa amakhadi kwimikhono yomntu kuya kudinwa ngokukhawuleza.

 

I-Syntek yenza i-passiveUmqondiso weRFID{0}}uvalela iimvelisokuzo zombini iifomati-zesilee kunye nepasipoti{1}}yefomati yesibambi. Okwangoku asenzi amakhadi ejamming asebenzayo.

 

Umsongelo weKhadi lokuFikelela okhoyo ngokwenene

 

Tsiba eli candelo ukuba sele uwazi umahluko phakathi kobuqhophololo bokuhlawula ngaphandle koqhagamshelwano kunye nokufikelela kwi-cloning yekhadi. Ukuba ezo zinto zimbini zivakala njengengxaki efanayo, qhubeka ufunda.

Kwaneyona HID iphezulu{0}}isiqinisekiso sokhuseleko sangoku, iSeos, inobuthathaka obubhaliweyo. Iphepha lika-2023 elipapashwe nge-International Association for Cryptologic Research (IACR ePrint 2023/450, uSam Haskins kunye noTrevor Stevado) babonise uhlaselo lokubuyisela ngokuchasene ne-HID Seos besebenzisa urhwebo ngaphandle -kwi-shelf hardware kuquka i-Proxmark3 RDV4. Uhlaselo lusebenzise i-intanethi njengomqolo we-relay, kunye neendawo ezimbini ezilungelelanisiweyo: enye ibekwe kufuphi nekhadi elisemthethweni, enye kufuphi nomfundi ojoliswe kuyo. Abaphandi bavule umnyango kwilebhu yabo ngelixa ikhadi eligunyazisiweyo lalibekwe malunga ne-1,960 km kude. Uhlaselo olufunekayo ngaphantsi komzuzu omnye wokuba kufutshane nekhadi, imeko enokwenzeka ngokupheleleyo kwindawo yokusebenzela ekwabelwana ngayo okanye kwi-elevator yokupaka.

 

Umkhono wokuvalela we-RFID awululungisi uguqulelo oluntsonkothileyo olwaphukileyo. Into eyenzayo kukususa iwindow ekufutshane. Ukuba isiqinisekiso singaphakathi kwendawo ebiyelweyo yeFaraday nanini na xa ingaboniswa ngokukhutheleyo kumfundi, umhlaseli akanaku qalisa ulandelelwano lokubuyisela okanye lokuhlanganisa kwasekuqaleni. Kwimibutho eqhuba isiseko sebheji yelifa enohlaziyo lwamaxesha alinganiswe kwiminyaka, lo ngowona -umlinganiselo ophantsi weendleko eziphathekayo ezikhoyo.

 

Ngomxholo othe kratya wendlela itekhnoloji yeRFID enxibelelana ngayo nemisebenzi yemihla ngemihla, jonga ushwankathelo lwethu lweizicelo eziqhelekileyo zeRFID kuwo wonke amashishini.

 

 

Apho Isiqinisekiso-Imikhono yoKhuselo SeyinguMbango oMgangatho

 

Ayiyiyo yonke imibutho ethatha oku njengento yokuzikhethela.

Yintoni ekufuneka uyithethe iNgcaciso yakho yokuThenga phambi kokuba uvume uMboneleli

 

Uninzi lwamaphepha emveliso aluyi kukunika into oyifunayo ukuze wenze isigqibo. Nantsi imibuzo emihlanu ekufanele uyibuze ngaphambi kokuba uvume isicelo sampulu.

 

 

Indawo yokuchaza	Iinkcukacha ezifunekayo
1. Ibhendi yefrikhwensi ekhuselweyo	Ichazwe njengenombolo. "Iibhloko ze-RFID" ayisiyiyo inkcazo. Kufuneka ubone "13.56 MHz," "125 kHz," okanye "dual-frequency".Imikhono esemgangathweni yeSyntek ithelekelwe i-13.56 MHz (HF/NFC).
2. Ukwakhiwa kwezinto	Buza ukuba yenziwe ngantoni umaleko wokuqhuba. Ulwakhiwo lweSyntek: iphepha eliqatywe ngaphandle, umaleko okhuselayo wefoyile yealuminium, ifilimu ye-PE yangaphakathi. Ukuthintela amanzi kunye nokukrazula{2}}ukuxhathisa.
3. Ukulingana komda	Imikhono kufuneka ifake i-ISO/IEC 7810 ID-1 imilinganiselo (85.6 × 53.98 mm). Ubungakanani obuqhelekileyo beSyntek: 88 × 59 mm kumakhadi, 140 × 97 mm yeepaspoti.
4. Ubunzulu bokuvula imikhono	Ikheji yeFaraday isebenza kuphela xa igqityiwe. Ukuvuleka okungenzulwanga okushiya umphetho ophezulu we-eriyali yekhadi utyhilekile kuya kuvumela abafundi abomeleleyo ukuba badibanise netshiphu.
5. MOQ & Ixesha lokukhokela	Iisampulu zasimahla (umthengi uhlawula ngenqanawa), MOQ 500 iziqwenga zemikhono engenanto, 1,000 yesiko{3}eprintiweyo. Ixesha lokukhokela i-7 ukuya kwiintsuku ze-15 zokusebenza. Intlawulo ngePayPal, T/T, okanye Alibaba.

 

Yintoni eyenziwa sesi Sleeve kwaye ayithathi ndawo

 

Ayintsonkothi data. Ayinakuqinisekisa abasebenzisi. Ayiphuculi iprotocol yekhadi lakho lelifa. Ukuba inkqubo yakho yofikelelo lofikelelo isebenzisa i MIFARE Yokudidiyela, umkhono awuzukwenza olo guqulelo lufihlwe nakuphi na ukophuka kancinane.

 

Into eyenzayo kukususa ifestile. Imizuzwana elishumi elinesihlanu umqeshwa wakho ehamba kwigaraji yokumisa izithuthi enebheji engakhuselwanga eklitshwe kwibhanti yabo? Kulapho uhlaselo lwe-relay luqala. Umkhono uvala loo msantsa. Ngokwe -ixabiso leyunithi liphantsi kwedola, ukusasazwa akufuni lutshintsho lwezakhiwo, kwaye ilinganisa ngeodolo enye yokuthenga. Kumphathi weziko owaziyo ukuba uphuculo lwekhadi luyimijikelo emithathu yohlahlo lwabiwo-mali, leyo yibhulorho efanelekileyo.

 

I-Syntek ibonelela simahla -iisampulu zemveliso ukuze ukwazi ukuvavanya ngokuchasene nenkqubo yebheji yakho yokwenyani phambi kokuba uzibophelele kumthamo. Sithumelele i-frequency card, ubungakanani obuqikelelweyo, kunye naziphi na iimfuno zoshicilelo. Siya kuqinisekisa ukuhambelana kwaye sithumele isampuli phakathi kweentsuku.
